Simone Pisana, an associate professor in the Electrical Engineering & Computer Science Department at York University’s Lassonde School of Engineering, recently made a fascinating, unexpected discovery concerning two unique layered crystals that could have a significant impact on the development of thermoelectric devices.

After examining thermal properties of two types of crystals – named rhenium disulfide and rhenium diselenide – with a special approach, Pisana and his graduate student Sina Tahbaz found that both materials exhibit an extremely valuable property known as thermal conductivity anisotropy.

Materials demonstrating this behaviour conduct heat differently depending on the direction of flow. For example, when heat flows across one direction of the material surface, it can exhibit high thermal conductivity, but when heat flows in another direction it can demonstrate low thermal conductivity.

Thermal conductivity anisotropy is a highly sought-after quality for many material applications, specifically the development of thermoelectric devices, like thermoelectric generators, that can recover waste heat and turn it into usable electric power. These generators are used in various niche applications, including space missions like the Mars Curiosity and Perseverance rovers.

By dissipating heat in one direction and blocking heat in another, materials exhibiting thermal conductivity anisotropy can also be used to improve the cooling efficiency of electronic components like sensors and lasers.

“To improve thermoelectric devices, it is beneficial to have a material that is both a good electrical conductor and bad thermal conductor,” says Pisana. “If we can figure out how to direct heat, we can help engineer materials that recover and reuse waste heat.”

Pisana’s groundbreaking discovery regarding rhenium disulfide and rhenium diselenide has the potential to advance the future of thermoelectric devices. However, before these materials can be put to good use, he wants to find the fundamental explanation behind his experimental results.

“This discovery is only the beginning of our work,” he says. “We don’t really have a good explanation for the behaviour of these materials yet.”

Much of the surprise behind the experimental results concerns the size of the anisotropy measured. In the case of rhenium diselenide, the thermal conductivity was found to vary by a factor of four within the crystal’s layers – this level of anisotropy has never been observed before.

“This discovery has really made us wonder: why are these materials exhibiting this behaviour; are there other materials that act like this; and how do we explain this?”

Now, the professor and his graduate students are preparing for complex research ahead, working backwards from their experimental findings to establish an accurate scientific theory.

“Heat transport is very difficult to accurately model down to atomic dimensions, so coming up with a theory behind the behaviour of these materials won’t be easy,” he says. “We are performing some computations with the help of Digital Research Alliance Canada to support our work. Even with advanced supercomputers it can take hours of computing for a small set of calculations. This project is going to require us to invest a lot of time and labour.”

This work is presented in the paper “Extreme in-plane thermal conductivity anisotropy in Rhenium-based dichalcogenides,” published in the Journal of Physics Materials as part of a special emerging leaders initiative. Being classified among other leading researchers has allowed Pisana’s work to gain increased recognition among broad scientific communities.

York University history Professor Marcel Martel and research assistant Alex Gagné have collaborated with the Archives of Ontario to launch a new online exhibit titled Wine Making in Ontario. Through images, maps and graphs, the exhibit surveys wine production in Ontario from 1866 to 1940.

Martel and Gagné proposed the exhibit based on their surprising research findings of an active pre-Second World War wine industry that spanned the province, from Windsor to Sudbury.

“When I conduct research on an issue, there are always some unexpected discoveries,” explains Martel. “I was surprised to discover the number of wineries and wine sellers in urban areas, especially in Toronto, and the multicultural ethnic origins of wine makers and sellers, since most of them came from Britain, France, Italy and the United States.”

The exhibit shows how European settlers struggled to use Indigenous-cultivated grape varietals to make European-style wines. It examines the background of various figures in the industry, including farmers seeking wealth and international acclaim, but also Jewish and Italian migrants and women who made wine for domestic consumption. It also considers the impact of prohibition and other headwinds that ultimately delayed the industry’s flourishing until the 1990s.

“As we continued our research, we expected to find a landscape of grape growers and vintners in competition – each vying for their share of the Canadian market,” says Gagné. “Instead, we found a story of co-operation and unity among the multicultural wine makers who dotted the 19th-century Canadian landscape.”

Among their many surprising discoveries, the researchers learned that early Canadian winemakers would share grape cultivation, harvesting and hybridization secrets through publications like Canadian Agriculturist. This collaborative spirit, Gagné explains, aimed to overcome the prevailing belief that Canada’s climate wasn’t suitable for winemaking.

“They sought to convince both the government and the public to embrace Canadian wines,” he says. “While ultimately stymied by the rise of temperance movements and prohibition, their efforts revealed an industry defined by shared knowledge – and, often, even shared vine cuttings – to prove to the world that Canada was home to unique and delicious wine.”

In support of the online exhibit, the Archives of Ontario has also prepared a display of archival records and historical artifacts related to Ontario’s wine history that can viewed until fall when visiting the Archives in person at 134 Ian MacDonald Boulevard, next to the Kaneff Tower on York’s Keele Campus. The Archives is open to the public from 8:30 a.m. to 5 p.m. every weekday.

‘We must never give up,’ Jane Goodall tells York community

Jane Goodall at podium BANNER

On April 9, at a special ceremony to award Jane Goodall with an honorary degree, the renowned primatologist and anthropologist shared stories from her life and career with attendees. She also shared why – despite the immense challenges the natural world faces at the expense of climate change – she has hope for the future.

“I still don’t really understand what’s happened to me,” she told the York audience about a career that has led her to become one of the world’s most famous anthropologists and primatologists. Nonetheless, she made an attempt to help those in attendance understand how she became the world-renowned figure she is today from – what she considers – a simple beginning.

“I was born loving animals,” Goodall explained, recounting how as a young child she would climb a tree and watch birds, squirrels, spiders and other creatures. If she couldn’t observe the magic of the natural world directly, she’d read about it indirectly through fantasy-tinged books like Tarzan of the Apes and The Story of Doctor Dolittle. With both novels’ ties to Africa, a seed was planted early for Goodall: she wanted to see the continent herself.

Goodall recounted how many questioned the logic of that newfound desire to travel to Africa and – perhaps – live with the wild animals like Tarzan and write books about them. “Everybody laughed at me,” Goodall said.

Throughout her address, she returned to the importance of the people most important to her journey, and among them was her mother who – even when she was young – never laughed at Goodall’s interest in animals. Once, when Goodall was very young, her mother found she had brought a handful of earthworms to bed. “Jane, you’re looking at them so earnestly, as if you’re monitoring how they’re walking without legs,” she noted. Then, very quietly, she nudged: “We better take them back to the garden.”

Goodall received a similar degree of gentle motherly guidance as she considered pursuing her interest in animals in Africa. “If you really want to do something like this, then you have to work really hard, take advantage of every opportunity, and if you don’t give up, hopefully you’ll find a way,” Goodall recalls her mother saying. “That’s the message I take around the world, particularly to young people, particularly to girls in disadvantaged communities.”

Goodall certainly took that message with her at the time, and did find her way to Africa, becoming a secretary to renowned British paleontologist Louis Leakey in Kenya. As Leakey began seeing Goodall interacting with local animals, he saw something in her. “He apparently decided that I was the person he’d been looking for to be the first to study chimpanzees in the wild,” Goodall said.

So, she did.

For a while, everything that would happen next – the exposure and support she received through National Geographic, the leadership she would demonstrate in guiding science to completely reconsider chimpanzee behaviour and more – would have seemed unlikely to Goodall when she began her immersive study.

The first few weeks were difficult. “For four or five months, the chimps took one look at me and vanished into the forest,” she recalled. She felt like she was making no progress. Goodall’s mother, who had volunteered to come with her to Tanzania, saw it differently, pointing to how in that limited time Goodall had already learned much about the chimpanzees: what they ate, how they communicated and what their communal dynamics were. “She said, ‘You’re learning more than you think,’” Goodall recalls of her mother.

Soon after there also came a turning point in the form of a chimpanzee she would come to call David Gray Beard. “He began to lose his fears [of me] before the others,” she said, which led to her getting close enough to him to observe an – at the time – revolutionary insight: chimpanzees could make and use tools. “That really changed everything,” Goodall said.

In time, Leakey wanted her work to be recognized by the scientific community, elements of which rejected her. Notably, they questioned the empathetic connection Goodall formed with the apes – something she, to this day, is known and beloved for. “’You cannot have empathy with animals and be a good scientist. You have got to be objective. You cannot be objective if you have empathy,’” she recalled being told.

That revolutionary empathy has been a landmark of not just Goodall’s work with apes, but advocacy for the natural world. That was something that especially flourished when she returned to Tanzania to start a research station after her first immersive study among the chimpanzees.

“I got to understand the ecosystem of the forest,” she said. “I see it as like a tapestry. And every time a species disappears from that ecosystem, you pull that thread from a tapestry. And if you pull in other threads, that ecosystem will collapse.”

She began to wonder what would happen if climate change were allowed to run unabated, or if humans don’t do something to control biodiversity loss. She could see first hand the impact poverty has on the environment, “because when people are poor, out in the rural areas, they’re destroying the environment simply to survive.” And the young people she would encounter were similarly concerned with the future. “Young people were losing hope. They were angry,” she said.

Addressing the students in the audience, Goodall admitted the old had have been compromising the future of the young for generations. However, Goodall said there is much that gives her hope. “If we get together, we can start to slow down climate change,” she said. She’s encouraged by many people throughout the world wanting to work to solve the challenges the Earth currently faces. “I’m sure there are students even right here working to try and solve particular problems,” she added.

“There is always hope,” she said. “We must never give up.”

York to host, lead graduate supervision conference

One of the foundational relationships of the graduate student experience is the one between student and supervisor. As part of its 60th anniversary celebrations, York University’s Faculty of Graduate Studies (FGS) is hosting an online graduate supervision conference geared specifically toward supervisors.

Held in partnership with Memorial University of Newfoundland, the conference – called Collaborative, Constructive, Considerate: Fostering Dialogue on Best Practices in Graduate Supervision in Canada – will be held virtually on Friday, May 31 from 9 a.m. to 3 p.m.

The conference will bring together graduate supervisors from universities across Canada, with the aim to lead and foster dialogue about best practices in supervisory pedagogy.

Cheryl van Daalen-Smith
Cheryl van Daalen-Smith

“We need to continue talking about principles and best practices,” says Cheryl van Daalen-Smith, conference Chair and associate dean, academic of FGS

The conference is intended to fill a need for schools of graduate studies, which understand that more conversations have to happen about supervision.

“There’s an assumption that one learns to be a supervisor by being supervised themselves,” she says, “when there’s so much more to it.”

A cornerstone of the academic environment, graduate education and the graduate supervisory experience play a pivotal role in shaping students’ academic and professional journeys. This relationship has a profound effect on the quality of research produced, development of academic skills and overall academic experience.

The conference will include a keynote address delivered by Bruce Shore, author of The Graduate Advisor Handbook: A Student-Centred Approach, titled “Connections to Quagmires: Setting Up for Successful Supervision.” A second keynote speech, by Supervising Conflict author Heather McGhee Peggs, will offer practical advice to help faculty manage the most common grad school concerns.

Experts in the pragmatics of supervision, mediating conflict and the requisite principles guiding Ontario universities will participate in a panel discussion to follow, examining the Principles for Graduate Supervision at Ontario Universities, which were developed last year by the Ontario Council on Graduate Studies.

A closing discussion moderated by van Daalen-Smith will end the day, with a focus on the Canadian Association for Graduate Studies Working Group Initiative and its mission to establish a set of national graduate supervision principles.

“We need to celebrate great supervision and foster discussions that identify exactly what it is that makes this pivotal educative role in graduate studies so influential,” says van Daalen-Smith.

The conference is free to attend, and registration is now open via the online form. For more information, visit the event web page.

York’s Institute for Technoscience & Society looks to shape public debate, policy

York University’s Institute for Technoscience & Society (ITS), established in 2022 as an Associated Research Centre of the new Connected Minds: Neural and Machine Systems for a Healthy, Just Society initiative, is on a mission to build a global hub focused on the complex relationship between technoscience – the scientific study of how humans interact with technology – and society. In particular, the institute is committed to unravelling the configuration of social power that underpins science, medicine, technology and innovation.

According to Professor Kean Birch, the inaugural director of ITS, the institute was established to cement York’s international standing and reputation in disciplines such as science and technology studies, communication and media studies, design, critical data studies, the history and philosophy of science, and other related fields in which York is a global leader. Aligned with the University’s Strategic Research Plan, especially when it comes to the topics of digital cultures and disruptive technologies, its members are actively engaged in research on the social, political, and economic implications of artificial intelligence (AI) and neuroscience.

Birch is enthusiastic about the future of research in this area: “We’re seeing a lot of interest in these topics,” he says, “especially in the societal implications of emerging technologies like artificial intelligence and other digital technologies.”

He insists, however, the institute’s depth in expertise is not limited to those areas, extending into topics such as the history of science through games design, the global governance of biotechnology and pharmaceutical innovation.

To support this diversity of knowledge, ITS is organized into the following four research clusters to help create synergies and support collaboration:

  • Technoscientific Injustices, which deals with the implications of emerging technoscience, its impacts on different social groups, and how to create just and inclusive science and technologies;
  • Technoscientific Economies, which deals with the entanglement of science and with different economies, what kinds of innovation get promoted by which kinds of economy, and how to support responsible and inclusive innovation;
  • Technoscientific Pasts & Futures, which deals with how the future of science and technology is bound up with our pasts and how the past helps us to build hopeful visions of and policies for the future; and
  • Technoscientific Bodies & Minds, which deals with the societal implications of prevailing understandings of health risks, diseases, and health-care delivery, as well as how prevailing understandings reinforce social injustices, inequities and divisions.

The institute is making its impact known in Canadian debates about the role of science and technology in society. Recently, Birch was interviewed by the CBC about the U.S. Department of Justice lawsuit against Apple Inc. for antitrust violations; and his recent opinion pieces about personal data as a collective asset and the social costs of generative AI were published in the Globe and Mail.

ITS plans to continue on this trajectory through regular events and policy briefing papers, as well as interventions in public and policy debates.

“York is incredibly well-placed to make an important social, political, and economic impact when it comes to these issues,” explains Birch, “because of the institutional strength and expertise of faculty and early career researchers here.”

York research examines complexities of sight

eye wide

Andrew Eckford and Gene Cheung, associate professors in the Electrical Engineering & Computer Science Department at the Lassonde School of Engineering, are developing a tool that can interpret the activity of cells involved in visual processes, enhancing our understanding of this complex biological system.

Whether we are admiring a beautiful landscape or watching an action-packed movie, our visual system is hard at work performing intricate biological functions that allow us to process and respond to visual information.

Andrew Eckford

Understanding the intricacies of the visual system is key to advancing research in biology, biomedicine and computer vision. Moreover, this understanding can aid in developing strategies to address visual impairments in humans.

Eckford and Cheung’s research is focused on nerve tissue behind the eye known as the retina. The retina is responsible for receiving images and sending them to the brain for processing using ganglion cells.

Many researchers have hypothesized that each ganglion cell type is responsible for computing specific features in a visual scene. For example, some cells may focus on information about the texture of an object, while others may process movement in a particular direction.

“From a big-picture perspective, we are trying to gain a better understanding of the visual system and how the eye processes information,” says Eckford. “We developed a tool that can analyze a data set of ganglion cell activity and identify relationships and patterns to predict exactly what they are looking at.”

Gene Cheung
Gene Cheung

Eckford and Cheung, and their graduate student Yasaman Parhizkar, proposed a graph-based tool that uses mathematical operations to discover patterns within a data set and make useful predictions about trends among the data points.

The proposed tool was tested using visual data gathered from a novel experiment led by University of Chicago Professor Stephanie Palmer. During the experiment, a film about an aquatic environment was projected onto the retinas of salamanders. The scenes resembled their natural habitat – imagine cool waters, sea plants and the occasional swimming fish.

As the film played, data concerning the salamanders’ ganglion cell activity was collected. The graph-based tool was used to identify and interpret trends within the data set and link these patterns to specific visual features in the film.

“It’s really cool to be able to take a data set of cell activity and see if we can predict exactly what the eye is looking at,” says Eckford.

Not only did the tool exhibit the capacity to interpret patterns within the data set and make useful predictions, but it also surpassed the abilities of comparable algorithms.

“Our tool addressed many of the problems that other algorithms have,” says Parhizkar. “Ours is much more interpretable and less data hungry.”

The applications of this unique tool can also be extended far beyond the field of biology, to industries such as agriculture, for making predictions about crop yield.

York research advances flood risk management with AI

In a recently published paper, Rahma Khalid, a PhD candidate in the Civil Engineering Department at York University’s Lassonde School of Engineering, and her supervisor, Associate Professor Usman Khan, proposed a promising new model for flood susceptibility mapping (FSM) that incorporates artificial intelligence (AI) machine learning (ML) methods.

Flood susceptibility mapping – the process of identifying potential flood-prone areas based on their physical characteristics – is a valuable technique used to identify areas that are vulnerable to flooding and inform risk mitigation and protection strategies. Unfortunately, conventional FSM methods rely on time-consuming physical and mathematical models that are also limited in their ability to predict flood risk across large regions.

“We have seen that physical and mathematical models can be very inconvenient for flood susceptibility mapping, especially when it comes to analyzing large areas,” says Khalid. “From a research perspective, we know that using machine learning can improve the speed and efficiency of different processes. This is why we proposed a flood susceptibility mapping model that is leveraged by machine learning for more accurate, rapid and reliable results.”

In their paper, titled “Flood susceptibility mapping using ANNs: a case study in model generalization and accuracy from Ontario, Canada,” Khalid and Khan document how they put their idea to the test and utilized an ML model to map out different regions in southern Ontario and determine their flood susceptibility.

Usman Khan
Usman Khan

They did so by using previously gathered data from different regions across southern Ontario, allowing the model to interpret, identify and predict areas that are at risk of flooding.

The model’s performance was also compared against conventional physical and mathematical models, as well as various emerging ML methods.

“When it comes to flood susceptibility mapping in real-world scenarios, machine learning models have not really been used,” says Khalid. “Industry members are also hesitant to apply these models because there is very little information about their accuracy and reliability.”

Khalid and Khan’s proposed model addressed limitations of other FSM models through training and testing that proved it to be a superior method for flood susceptibility mapping, outperforming other models. It even demonstrated novel capabilities that can help advance the future of flood risk management.

“Our model demonstrated a novel ability to accurately predict flood susceptibility, even across areas that we did not provide training data for,” says Khalid. “Knowing this, we can work towards training our model to understand more about different regions and further improve its ability to predict flood susceptibility in larger areas.”

Currently, Khalid and Khan are working on enhancing the performance of their model with a particular focus on improving data resolution, as well exploring the possibility of supplementing their model with additional ML methods.

Schulich partnership seeks to address global infrastructure gap

Schulich Real Assets – an area within York University’s Schulich School of Business that focuses on tangible investments – is teaming up with the Global Infrastructure Investor Association (GIIA) to offer the next generation of leaders more tools and resources to help them tackle the climate crisis through sustainable infrastructure projects.

Schulich is one of a few schools around the world offering graduate education focused on the increasingly important and evolving real assets field, with both a master of business administration specialization in real estate and infrastructure and a unique, 12-month Master of Real Estate and Infrastructure program.

This new partnership is designed to help increase private investment into infrastructure projects that are supporting the global transition to cleaner energy.

“We look forward to working together with GIIA and its members towards the common goal of promoting an infrastructure investment ecosystem that mobilizes private capital,” said Professor Jim Clayton, the Timothy R. Price Chair in Real Estate and Infrastructure at Schulich and the MREI program director. “We are excited by the alignment and synergy of the collaboration.”

Through new research and educational programming opportunities, Schulich students will now be empowered with knowledge and resources to deliver the infrastructure that communities need to thrive, with GIIA’s global membership base also helping them to expand their networks and experience.

“It is critical to empower emerging leaders in our industry with the skills and specialist knowledge that enables them to unlock the potential for infrastructure investment, so we can grow the market, and bring in the capital to make the major investments that governments alone cannot afford,” said Jon Phillips, chief executive officer of GIIA, which represents 100 of the world’s leading investors and advisors in infrastructure.

“Since Canada is already a hub for innovation in the infrastructure investment industry, partnering with Schulich makes good sense,” he said.

Professor’s book explores health inequality in Canada

Health sign made of wood on a natural desk

A new third edition of the book About Canada: Health and Illness, written by York University health policy and management Professor Dennis Raphael, explores social determinants of well-being in Canada and provides updated information connecting health and illness to the worsening levels of inequality throughout the country.

Dennis Raphael
Dennis Raphael

In About Canada, Raphael – an expert in covering health inequality – argues that the inequitable distribution of the social determinants of health is structured by Canada’s political economy, including public policy decisions.

According to Raphael, and his book, while some common wisdom might dictate that our lifestyles – exercise, food choices and more – affect our health, the truth is altogether different. Instead, he says, it is how income and wealth, housing, education and adequate food are distributed, as well as employment status and working conditions, that determine whether we stay healthy or become ill. Furthermore, who gets to be healthy is too often a reflection of social inequalities that are associated with class, gender and race in Canadian society.

The new edition of About Canada points toward how – based on tent cities becoming more common, food bank use hitting record high levels and more – ongoing health inequalities have only escalated since the first edition of his book was released in 2010.

“The social determinants of health situation in Canada has become so problematic as to constitute a polycrisis whereby growing food and housing insecurity, income and wealth inequality, precarious and low-paid work, social exclusion and declining quality of public policy threaten Canadians’  futures,” says Raphael. “The declining Canadian scene not only compelled a documentation of this situation but also formulating a vision of dramatic reform or even transformation of our profit-driven economic system.”

In addition to updated information throughout the book that better reflects the current moment, a new chapter also considers the social determinants of who got sick and died from COVID-19, and how the pandemic makes a clear case for restructuring work and living conditions through public policy that more equitably distributes economic resources.

Raphael’s goal is for the latest edition of the book is to provide important context for readers. “Hopefully, the new edition will provide Canadians with a means of understanding the Canadian polycrisis and means of moving beyond it,” he says.

The third edition of the book will be published on May 2 and is available to purchase through Fernwood Publishing.
