Urban Studies students advance learning with Montreal field trip

Living in the Greater Toronto Area, it’s not complicated for students in the Cities, Regions, Planning program at the Faculty of Environmental & Urban Change (EUC) to assess Toronto’s strengths and weakness, but an annual field trip to Montreal allows them to apply their analytical skills elsewhere.

For five years, Teresa Abbruzzese, an assistant professor and urban geographer, organized a field school – a short-term academic program consisting of mentored field research – in the fall for third-year Urban Studies students in her research methods course in the Department of Social Science in the Faculty of Liberal Arts & Professional Studies.  

She was excited to bring this experiential learning opportunity to her new home in the Cities, Regions, Planning program for her third-year course, Doing Urban Research: Theory & Practice, for the Fall 2024 term. 

The initiative gives students a chance to experience another city, using participant observation while taking notes and photos and having conversations with local citizens. The trip is mandatory and the costs are low, but there is a day trip to Hamilton, Ont., for a cheaper alternative. 

“The trip enables our students see the historical and contemporary issues facing Montreal and to develop a comparative understanding of cities,” said Abbruzzese. “It’s also important to give them the opportunity to do preliminary fieldwork.” 

“The point of the trip is to prepare them to work on their own individualized research project,” she said. “It trains them to be social scientists and allows them to hone their academic skills, such as critical analysis, research and writing.”

The Montreal field school emerged from a political moment in history when Donald Trump assumed the American presidency in 2017. Abbruzzese and her colleagues in Urban Studies at the time decided to halt the field school to Buffalo – the original international location of the field school for many years – and instead they chose Montreal as the setting.  

Once the Canadian city was decided, Abbruzzese thoroughly enjoyed the creative process of putting together a new field school.  

“Logistically, it’s never easy to execute, but I strive to enhance the field school experience each year,” she said. “All the guest speakers make this field school special and welcome our urban group from York University back each year.” 

She, her students, and other professors boarded a Megabus for the ride east and followed a packed itinerary that included historian/expert-led walking tours of neighbourhoods such as Saint-Henri, Montreal North, Little Burgundy and Mile End; a visit with City Councillor Sterling Hall – who has experienced homelessness – and a tour of City Hall; and talks by professors from Concordia University.  

The students packed a lot into the trip, getting a sense of the richness and diversity of Montreal. They saw poverty and affluence, arts and industry. They gained an understanding of some of the city’s challenges with issues such as housing, transportation, socioeconomic disparities, public spaces and heritage as well as the French-English divide, said Abbruzzese. 

“All of this sparks comparative analysis in their heads and they begin to ask a lot of questions,” she said. “They’ll use all of this to create a manuscript – a fieldwork diary organized around themes. They’ll organize, reflect, and analyze their empirical notes and contextualize their observations with broader scholarly conversations in Urban Studies.” 

Just as important, noted Abbruzzese, is that the trip serves to transform the class from individual students into a community.  

“It is a tradition for professors from the program to join this field school, so that students have an opportunity to get to know the other professors in the program, and professors get to know the students,” she said. “Professor Doug Young from the Urban Studies program has joined me on this field school from Buffalo to Montreal for the last eight years. Students have always appreciated sharing this experience with other professors from the program, which made the experience more memorable.” 

“In addition, students become a support network for each other and become more connected after this field school,” she said. “They’re all friends afterward.”

Vanessa Reynolds, a third-year geography and urban studies major, confirms that. “This was a group that hadn’t talked to each other in class, but we all bonded and, now, we’re really friends,” she said. “It was such a great experience; I’d recommend that anyone do it.” 

She found the trip eye-opening in many ways, and changed her perspectives. 

“I’m so Toronto-centric, but seeing Montreal gave me deeper insights into how a city runs, and seeing different parts of the city that people often don’t was amazing,” Reynolds said. Furthermore, she added, “I want to travel more. It makes you want to see the world. It was an experience that made university different.” 

Shazde Mir, a fourth-year urban studies major who plans to pursue a career in policy development or community planning, said Abbruzzese’s passion for Montreal made her glad she took the trip, as she got to know the city and gain insights into city planning. 

“I saw a different perspective of what it means to be an equitable city,” Mir said. “You can’t treat people as less than.” 

After visiting a working-class neighbourhood with prominent community initiatives that reminded her of Toronto’s Jane and Finch area, Mir wondered why cities have areas where a lack of investment from the government is visible. 

“I’ve started looking into tours here in Toronto to get to know the history of the city’s development,” she said. “I want to go back to Montreal and I’d like to visit other cities to see how different governments went about developing them, what the priorities were. 

“The trip solidified my love for Toronto. I want to see more progressive policies so we can create a more equitable city.” 

Ultimately, said Abbruzzese, “our objective is to produce graduates who are informed, critically engaged, and sensitive to issues of sustainability, social justice, equity and diversity.” 

Given the feedback, it is apparent she is meeting that goal.

The Guggenheim Foundation is a beacon of excellence in supporting scholars, artists, and researchers in their endeavours to push the boundaries of knowledge and creativity. This year, 188 culture creators working across 52 disciplines were named Guggenheim Fellows, selected on the basis of prior career achievement and exceptional promise, and rewarded with both recognition and monetary prizes.

This honour is a testament to Sharpe’s contributions to the field of Black studies and her innovative approach to research and writing. Her trailblazing work has resonated with scholars and readers alike, shedding light on important issues related to what she calls the “ordinary extraordinary matter of Black life.”

“As a member of our faculty, we are truly delighted and honoured to witness her exceptional achievements,” says J.J. McMurtry, dean of LA&PS. “She is not simply being acknowledged for her outstanding contributions but is being rightly celebrated on a global scale. Her outstanding success serves as a source of inspiration and pride for our entire academic community, highlighting the calibre of talent and dedication that thrives within our Faculty.”

Sharpe’s recent works have garnered significant acclaim, with her book Ordinary Notes (Penguin Random House Canada, 2023) earning her the Hilary Weston Writer’s Trust Prize for Nonfiction and being selected as a finalist for the National Book Award for Nonfiction. Ordinary Notes was further recognized as a best book of the year by esteemed publications such as the New York Times, The Atlantic, The New Yorker, the Globe and Mail, the Toronto Star, NPR, New York Magazine and literary magazine Granta. This month, Sharpe was also awarded a Windham-Campbell Prize for nonfiction.

Beyond the many recent accolades, Sharpe remains immersed in her upcoming projects – What Could a Vessel Be? and Black. Still. Life. – showcasing her ongoing commitment to exploring and engaging with important themes through her writing.

“I am very glad for the support of the Guggenheim Foundation toward completing What Could a Vessel Be? and to be among so many writers, artists and thinkers whose work I respect,” says Sharpe.

Psychology professor brings community to the classroom

Students collaborating around table

York University psychology Professor Lesley Zannella changed things up in her recent Critical Thinking in Psychology course by offering students the opportunity to bridge the gap between classroom and community.  

In a year-long, fourth-year psychology capstone course of approximately 60 students, Zannella first helped students build the foundational skills of critical thinking during the fall term, and then allowed them to translate those skills into real-world scenarios in the winter term, through a community-based project. By engaging with community organizations, students were encouraged to critically analyze psychological research, apply theoretical knowledge to practical situations and develop creative solutions to challenges as they arose.

“It is important to me that students in this course not only develop the ability to be critical consumers of research in psychology but that they also develop the ability to communicate that research in an accessible way,” said Zannella.    

Working alongside Sophie Koch and Paola Calderon-Valdivia, the Faculty of Health’s experiential education co-ordinators, Zannella partnered with five local community organizations dedicated to supporting various underserved communities: the Writers Collective of Canada (WCC), Innocence Canada, the Remedy Institute, the Haven Mental Health Wellness Centre and Progress Place.

“By fostering partnerships with organizations that support underserved populations,” Zannella explained, “I sought to facilitate a collaboration between academia and the community with the shared goal to promote empathy and social change.”

Zannella divided students into 10 groups and assigned each community partner to two of the groups. In advance of the student involvement, the professor worked with each community partner to design and develop a project that responded to the needs of the organization and aligned with the learning outcomes of the course.

“One of my teaching strategies is to facilitate opportunities for students to strengthen employer-valued skills such as critical thinking, communication and collaboration” said Zannella.

Each week, students collectively worked on the community-based projects within the classroom. They also participated in three touchpoint meetings with their community partners throughout the term.

Working with Lisa Endersby, an educational developer at York’s Teaching Commons, Zannella developed an assessment structure that would provide students with the opportunity to reflect on their experience. Their reflections were overwhelmingly positive, and many indicated interest in pursuing future studies or career paths related to their community organization.

“I love the experiential learning opportunity that this project has provided me. I am applying the theoretical concepts and research processes I’ve learned within the academic space to a practical challenge,” wrote psychology honours student Megalai Thavakugathasalingam, who believes every psychology student should participate in a program like this one. “I have also been stretched to critically reflect and creatively develop a solution on behalf of the organization, which has provided me with a real chance to consider how academic research can be disseminated and benefit everyone.”

Psychology honours student Blake Haig echoed those sentiments: “This experience showed me the transformative potential of collaborative learning environments,” he said. “This class not only challenged my preconceived notions about group work but also instilled in me a new-found appreciation for the power of community in academic pursuits.” 

Shelley Lepp, CEO of collaboration partner WCC, who worked with York students to identify best practices in training for volunteer facilitators of community writing workshops, sees the value of this initiative for both parties – to help establish relationships that will lay the groundwork for future progress.

“As a charitable arts-health organization deeply committed to alleviating isolation and loneliness for those most vulnerable, we know these students will one day be our partners on the front lines,” she said. “Connecting with them in this context and in this moment empowers us both to understand how clinical and community supports can work together to improve mental well-being for all.”

York receives $300K boost for research commercialization

Concept of idea and innovation with paper ball

York University’s Office of the Vice-President Research & Innovation (VPRI) and the IP Innovation Clinic have received a second instalment – the first was received in 2023 – of $300,000 from the government of Ontario to advance its commercialization services, particularly for research and innovation related to artificial intelligence, automotive and medical technology.

The funding, announced on April 8 by Jill Dunlop, minister of colleges and universities, is from Intellectual Property Ontario (IPON), a provincial agency that provides IP support for Ontario businesses and researchers.

This marks the second year in a row the initiative has received $300,000 from the government as it works towards increasing patent filings, outreach and consultation.

“IPON’s continued and valued investment in York helps advance the University’s commitment to helping our researchers realize the full potential of their innovative work and amplify their community impact,” said Amir Asif, vice-president research and innovation. “Strengthening commercialization efforts at York and supporting entrepreneurs in the province through education and training create positive change for the people of Ontario and the province.”

The funding will enable the collaborating units to continue to provide a suite of intellectual property and commercialization services to researchers and their partners, with the goal of taking more of the University community’s great ideas from the lab to market. 

“Together with countless law students and our industry partners, we have saved over $2 million in legal fees to resource-scarce innovators seeking to commercialize their IP and grow Canadian companies. We look forward to fostering the success of many more,” said Pina D’Agostino, associate professor at York’s Osgoode Hall Law School and the founder of the IP Innovation Clinic. “We are grateful to Minister Dunlop and Intellectual Property Ontario for supporting the IP Innovation Clinic for a second year.”

D’Agostino continued: “Ultimately, this is also a big win for our students who can continue to get access to first-rate experiential learning to make them job-ready while helping those who do not have access to legal resources.”

York was one of 10 universities with an existing program to receive the renewed funding, totalling $1.7 million. IPON also announced a new investment of $2.9 million to help commercialize research at 10 institutions across Canada.

“This funding will help institutions across the province more effectively translate research into commercializable innovations, while ensuring the IP at their foundation is appropriately developed and protected,” said IPON CEO Dan Herman.

“Through the province’s support of IPON, our government is ensuring the social and economic benefits of publicly funded research stay in our province, so that Ontarians and the Ontario economy benefit from these new discoveries and innovations,” said Dunlop.

Prof’s discovery could advance future of thermoelectric devices

Engineer using tablet outside of energy generator plant

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.

Simone Pisana
Simone Pisana

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 researchers launch exhibit documenting Ontario’s wine history

grapes on a vine

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.

Marcel Martel

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.

To view the online exhibit, visit Wine Making in Ontario (or La fabrication du vin en Ontario for the French version).

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.
