Zoe M. Savitsky, a doctoral candidate at York University’s Osgoode Hall Law School, was named a Pierre Elliott Trudeau Foundation Scholar for work that promises to examine the ways corporations gained the power of expression and how they have expanded and defended that power. The recognition marks not just a professional accomplishment for Savitsky but one reflective of a new chapter in her journey.

Before becoming a PhD student at York U in 2023, Savitsky approached her legal work in an altogether different manner. For over a decade, she had a successful legal career in the United States working in high-impact government and non-profit organization litigation and leadership roles, including at the Oakland City Attorney’s Office, the Civil Rights Division of the U.S. Department of Justice and the Southern Poverty Law Center.

As a Trudeau Scholar, Savitsky will pursue work rooted in experiences from her legal career, notably her time with the Oakland City Attorney’s Office. There, Savitsky collaborated with in-house teams, other local and state governments, non-profits, civil society groups, and the private bar on litigation involving local, national and multinational corporations – such as opioid companies, fossil fuel companies and real estate companies – whose actions harmed Oaklanders. Many of those cases centred on allegations that the corporations in question had engaged in false, deceptive or misleading speech that caused real-world harm.

Savitsky found herself considering larger questions around how modern systems of litigation sometimes allow corporations to “get away” with harmful deception. As she noted, it has often taken decades for litigants to win cases about corporate deception, if they ever do, citing as examples cases about how tobacco companies misled the public about the health risks of tobacco; how paint companies continued advertising lead paint despite their knowledge that it was a dangerous neurotoxin; and how the opioid industry understated the risks and harms and oversold the benefits of its products.

“My current project is very much an extension of all of that work,” says Savitsky of the work she will now pursue through her scholarship, which examines how corporations became legal persons with speech or expression rights, and how corporations have expanded and defended those rights in the litigation ecosystems of the United States and Canada.

“I hope to understand how things came to be as they are today in the world of transnational corporate accountability and, in particular, to understand the history and context for how it is often challenging to hold corporations meaningfully accountable for their contributions to some of the most existential problems facing the world today.”

The decision to pursue academic work led Savitsky to Canada, eager to grow as a scholar and learn from people outside the United States who were working on corporate accountability, but it wasn’t easy to move away from a professional and personal support system built over decades. “Leaving that network – which includes people who have become not just colleagues but close friends – for a new country and context was hard,” says Savitsky. “But as my scholarship draws on the issues and themes I had the opportunity to work on in my litigation career, I will continue to get to engage with many of the people I collaborated with and learned from in the past.”

Nonetheless, she saw the move as worthwhile. “Opportunities like the Trudeau Scholarship will allow me to build anew in this new context, in addition to how I’ve already had the chance to start building meaningful new relationships at Osgoode and at York more broadly,” Savitsky says.

The recent recognition from the Pierre Elliott Trudeau Foundation should prove a significant stepping stone in accomplishing that.

The Trudeau Foundation Scholarship is a prestigious, three-year leadership program that provides doctoral candidates with skills to translate their ideas into action, for the betterment of their communities, Canada and the world.

It also provides a strong communal element through fellows and mentors who are leaders in respective disciplines and offer scholars important guidance as they move forward in their careers.

“From the beginning, my interest in the Trudeau program has been because of its people,” says Savitsky. “I appreciate the resources the scholarship provides to PhD candidates, but the people are the fundamental heart, and draw, of the foundation. Of course, I am also thrilled that the Trudeau Foundation’s scientific cycle centres the Canadian Charter of Rights and Freedoms, which is at the core of my doctoral work.”

Savitsky hopes that through her work, now supported by the Trudeau Scholarship, she can make a positive impact in the field of corporate accountability – and beyond. “I also hope the story I plan to tell through my doctorate is informative to people outside of the legal academy, including to those in other academic disciplines, such as political science, and to those actively working – whether for governments, for non-profits and NGOs, in civil society, as community leaders and so on – to make the world a better, safer, healthier place overall,” she says.

Professor recognized for exemplary lifetime contributions to the study of Earth

View of the Earth from space

York University Professor Spiros Pagiatakis received the Canadian Geophysical Union’s J. Tuzo Wilson Medal, which recognizes a Canadian scholar’s outstanding contributions throughout their career to the geosciences – the study of the Earth – and counts as the highest national honour earned by those in the field.

“I am deeply honoured and privileged to be awarded the highest accolade of geosciences and join the previous 45 laureates,” says Pagiatakis of the medal, which was given to him in recognition of a lifetime of contributions to the advancement of knowledge and education in Canadian geosciences. He is only the third York-affiliated person to receive the award.

Pagiatakis joined York U in 2001, after already having made a nearly decade-long impact in the field as a lead senior research scientist for the federal Department of Natural Resources Canada. In both his professional and academic careers, Pagiatakis has dedicated himself to the study of the Earth as observed from terrestrial and space platforms, with highly innovative work and discoveries starting from the Earth’s inner core motions. He has specialized in measuring and understanding the planet’s geometric and physical shape, and how its internal forces – like plate tectonics – bend form, deform and more, as well as how its atmosphere and gravity operate.

Pagiatakis has tackled innovative research questions across the spectrum of geodesy and Earth sciences, with groundbreaking findings that led to the recent recognition.

Among Pagiatakis’s innovations in the field, he pioneered a better understanding of deformation of the Earth due to the dynamics of ocean tides, as well developed the first map of Canada and the U.S. showing how gravity changes with time due to the rebounding of the Canadian land mass due to climate change and the melting of the ice since the last ice age glacial maximum, some 23 thousand years ago.

Since joining York U, his interests have shifted to space science, which has led to important discoveries highlighting how dynamics in the Earth’s lower and upper atmosphere influence, impact and shape climate science.

Pagiatakis’s work has been recognized and funded by the Natural Sciences & Engineering Research Council of Canada, the GEOIDE National Centre of Excellence, the Carbon Management Canada National Centre of Excellence, the Canada Foundation for Innovation, Ontario Innovation Trust and Natural Resources Canada.

Pagiatakis’s impact has also extended beyond research by influencing future generations in the field, notably at York University. He was one of a handful of pioneers who created the first engineering programs and accreditation at York U, which ultimately led to the founding of the Lassonde School of Engineering, where he served as the inaugural associate dean of research and graduate studies for five years. He has also led the development of innovative methods of teaching in a virtual classroom environment and in blended course delivery to university students and engineering professionals before online teaching became commonplace.

A lifetime of efforts aren’t limited to the administrative, however. Pagiatakis has been a passionate teacher, deeply invested in collaborating and supervising graduate students to help guide the next generation of pioneers in the field of geophysics. Former students – many of whom now work for top organizations like NASA, the European Space Agency and the GFZ German Research Centre for Geosciences, and in academia in Canada and abroad – credit him for providing high-quality graduate education, training and mentoring opportunities in an equitable, safe, welcoming and encouraging environment built on trust, where acceptance, openness, motivation, enthusiasm and curiosity have been paramount.

For his part, Pagiatakis is reluctant to take too much credit for what he has accomplished. “My graduate students are the heart, the soul and inspiration of our research; without them nothing would be possible” he says.

Nonetheless, as one of his J. Tuzo Wilson Medal nominators emphasized, Pagiatakis “is one of those exceptional scientists who do not shy away from various administrative and organizational duties someone has to undertake in order to keep science healthy.” His dedication to doing just that – keeping his field of science thriving with his career, academic work and mentorship – are what now have earned him the recognition his students would agree he’s long deserved.

Digital inclusion plays key role in financial inclusion, according to new Schulich study

The research findings are contained in the paper “Digital Inclusion and Financial Inclusion: Evidence from Peer-to-Peer Lending,” published in the Journal of Business Ethics. The paper was co-authored by Kiridaran (Giri) Kanagaretnam, a professor of accounting and the Ron Binns Chair in Financial Reporting, Banking and Governance at Schulich, together with Xiaoran (Jason) Jia, an assistant professor of accounting at Laurier University’s Lazaridis School of Business & Economics and a former PhD student of Kanagaretnam’s.

“We found robust evidence that digital inclusion – a public policy designed to provide high-speed internet infrastructure for historically digitally excluded populations – is positively associated with the greater access to capital by people from marginalized communities,” said Kanagaretnam.  

The study generated a number of additional findings, including the discovery that digital inclusion may contribute to higher lending rates due to the availability of more information about borrowers that assist lenders in their decision-making process, and the strong likelihood that digital inclusion may facilitate faster loan approvals. 

The research findings also showed digital inclusion led to higher lending penetration in areas underserved by traditional banks as well as areas with greater minority populations.

“These results suggest that digital inclusion plays a key role in financial inclusion, particularly in regions with more vulnerable and/or underserved populations,” noted Kanagaretnam.

“Our new programs in vaccine production and biotechnology aim to bridge talent gaps in the pharmaceutical industry in Canada and to offer students and professionals a variety of training options for upskilling for industry jobs,” says Hovig Kouyoumdjian, associate dean of curriculum and pedagogy in the Faculty of Science.

Spearheaded by Kouyoumdjian and faculty members Jade Atallah, the Markham biotechnology graduate program director, and Luz Adriana Puentes Jácome in the Department of Biology, the micro-credential in Vaccine Production and Quality Assurance will provide accelerated, experiential and industry-centred training on the fundamentals of vaccine production, including emerging technologies.

“It will be offered as an eight-week, blended program, shaped by input from a variety of industry partners,” says Jácome. “The micro-credential offers more rapid, vaccine-focused training relative to the new Graduate Diploma in Biotechnology and Master’s in Biotechnology Management programs, which are broader in scope and completed in one year or two, respectively.”

With the new funding, the Faculty of Science will also purchase new equipment that will not only benefit student training in the micro-credential but also the Master’s in Biotechnology Management and Graduate Diploma in Biotechnology programs starting this fall at Markham Campus. The equipment will include cell culture tools for various expression systems (bacterial, yeast, insect and mammalian cells) and novel vaccine platform technologies (DNA, RNA and recombinant proteins) that are highly aligned with current advancements in the vaccine industry.

“Given the focus of these biotechnology postgraduate programs on applied training, the new equipment will support a curricular delivery that is hands-on and highly experiential in nature,” says Atallah. “Our students will complete their training with the knowledge and skills they need to secure in-demand jobs in the biotechnology and vaccine production industry.”

“We are grateful to the Ontario Ministry of Colleges & Universities for supporting the creation and enhancement of these important programs at York University,” says Kouyoumdjian.

Lassonde partnership leverages 3D printing to address housing crisis

Recently, Liam Butler, an associate professor in the Department of Civil Engineering, teamed up with construction company Printerra, which offers 3D construction printing. Together, they are helping to address Canada’s growing demand for affordable and sustainable housing by manufacturing 3D-printed concrete homes. Using state-of-the-art printing technology and low-carbon concrete materials, the project’s goal is to transform the future of housing construction by reducing both labour costs and construction time.

In support of this initiative, Butler received funding through the Natural Sciences & Engineering Research Council of Canada’s Alliance Advantage program. In addition to aiding research objectives, this funding will allow for the training and recruitment of graduate-level student researchers, who will have the opportunity to advance their engineering skills through lab testing and field monitoring.

“The major goals of this project are testing the feasibility of 3D-printed concrete homes and their long-term performance against different climate conditions,” says Butler.

This project will take advantage of innovative facilities at Lassonde, including the High Bay Structures Lab and the Climate-Data-Driven Design (CD3) Facility – a unique space that allows for outdoor testing and monitoring of natural and infrastructure materials to evaluate their performance under realistic climate conditions.

“Printerra is the first industry partner to directly undertake work at the CD3 Facility,” says Butler. “This project fulfills the entire vision of the facility, and we hope it will put us on the map and generate further interest from industry partners.”

In addition to performance testing, Butler will focus on the development of low-carbon concrete mixtures that can be used to 3D print structural components.

Similar to 3D printing with plastics and metals, using concrete involves the successive deposition of thin layers of material through an extrusion nozzle. The properties of the concrete must be closely controlled to ensure each layer hardens and holds its shape prior to adding the next layer.

Typically, these mixtures contain significant amounts of Portland cement, a conventional material used to make concrete – and a significant contributor to global carbon dioxide emissions. By developing new, low-carbon concrete materials, Butler will establish a sustainable alternative to conventional concrete, helping to offset the associated carbon footprint of 3D-printed housing.

This project also gives student researchers the chance to collaborate with industry professionals and achieve research outcomes that directly relate to industrial applications. Such opportunities are crucial for career preparation, offering learners hands-on experiences and connections that are invaluable as they transition from academia to their professional careers.

“This project is going to demonstrate the strong potential of 3D-printed concrete homes while building trust in new, low-carbon concrete materials and construction technologies – it is a very exciting time for our research group,” says Butler.

Lassonde prof explores optical imaging for heart attack prevention

hand holding heart near stethoscope BANNER

Heart disease is a leading cause of death in Canada and the U.S. Understanding the severity of the disease in patients is crucial for preventing complications like heart attacks – and researchers across the globe are racing toward solutions to avoid such devastating outcomes.

Over the past few years, Nima Tabatabaei, an associate professor in the Mechanical Engineering Department at York University’s Lassonde School of Engineering – along with his former PhD student Mohammad Hossein Salimi and Professor Martin Villiger, a researcher at Massachusetts General Hospital and Harvard Medical School – has been working to develop a new intravascular imaging technology to enable early detection and prevention of heart attacks.

Nima Tabatabaei

“When aiming to prevent heart attacks,” Tabatabaei says, “a major point of interest is early detection of unstable atherosclerotic plaques.”

These plaques are made up of fatty substances known as lipids, which can accumulate in different arteries throughout the body.

“If an atherosclerotic plaque ruptures, patients can experience a heart attack,” he says. “However, not all plaques will rupture. A major issue is that cardiologists don’t have a reliable way of distinguishing plaques that are problematic from those that are not.”

Tabatabaei’s new technology, called photo-thermal optical coherence tomography (PT-OCT), can distinguish rupture-prone plaques from stable ones based on their distinct structure and chemistry. An enhanced version of a biomedical imaging technique called optical coherence tomography (OCT), which is primarily used to diagnose eye diseases, PT-OCT uses two lasers as well as principles of interferometry – a measurement method using the interference of superimposed waves to extract information – to capture light scattering and absorption from biological tissues. This generates high-resolution images that show both plaque structure and tissue chemistry, providing an objective tool for assessing the risk of atherosclerotic plaque rupture.

“OCT is one of the most widely used optical imaging methods in clinical settings,” explains Tabatabaei. “Our idea was to include additional lasers to the system at specific wavelengths, allowing for absorption by the chemistry of unstable plaques.”

Although PT-OCT is a promising method for imaging atherosclerotic plaques, it is not currently being used in clinical settings for this purpose.

“Very few labs have access to this technology,” says Tabatabaei, “and it can also be quite slow, complicated and hindered by noise.”

Throughout the past four years, Tabatabaei and his research team have worked to address several fundamental and technological challenges of PT-OCT, while exploring innovative ways to improve this method for the purpose of imaging and characterizing atherosclerotic plaques.

In a recent paper published in the prominent journal Scientific Reports, Tabatabaei explored the use of an artificial intelligence method to improve the signal-to-noise ratio of PT-OCT signals and contrast of PT-OCT images. Neural networks were designed and trained with experimental data, allowing the system to better predict specific structural and chemical features in images. This work also created opportunities to significantly improve imaging speed and efficiency.

Through previous research, the team studied the implications of PT-OCT signals and their relationship with biological tissue, linking optical signals to corresponding chemical structures. They also investigated ways to improve additional qualities like accuracy, working toward practical use in clinical settings.

Detecting and characterizing atherosclerotic plaques, this imaging technology boasts the potential to transform the future of heart attack detection and treatment, ultimately improving patient outcomes. Moving forward, Tabatabaei will continue to apply his expertise in biomedical optics to improve PT-OCT and explore additional applications, contributing to ongoing efforts of combatting heart disease.

Schulich partnership to help companies track climate performance

Modern city and environmental technology concept

York University’s Schulich School of Business, the top ranked school in Canada for sustainability, has joined forces with Corporate Knights, one of the world’s leading sustainable economy media and research companies, to develop one of Canada’s first climate finance indexes. The new national index will track and measure corporate spending targeted at accelerating decarbonization efforts.

The index will serve as a useful tool for companies to track and measure their climate performance against peers within their industries while also providing important information for governments formulating public policy decisions around decarbonization.

Professor Olaf Weber, the CIBC Chair in Sustainable Finance at Schulich, is spearheading the initiative on behalf of the school. According to him, the development of a climate finance index “addresses the uncertainties around what companies really do to achieve their climate goals.” Adds Weber: “An index that addresses how much companies invest to achieve their goals presents a more objective indicator than general announcements in sustainability reports.”

As part of the process of developing the index, Corporate Knights and Schulich hosted a session on June 26 involving two dozen leaders from the building, transportation and power sectors who engaged in a cross-sector approach to find ways to measure decarbonization. The session took place in the former Toronto Stock Exchange boardroom at Schulich’s Miles S. Nadal Management Centre and was moderated by public policy expert Diane Fox Carney.

Corporate Knights magazine will soon publish a synthesis report detailing Canada’s climate investment gap and will unveil the new climate finance index, with index weightings by sector to show Canada’s climate investments versus requirements. Sustainability experts from Schulich will provide in-depth analysis of the results.

Pictured, left to right: Ali Abdul-Sater and Mark-David Hosale.

Abdul-Sater’s project, “Investigating the effects of emerging chemical mixtures associated with air pollution on immune-related diseases,” will study the potentially worsening effects that new types of pollutants from chemicals in tires and brakes, pesticides and household products are having on inflammatory diseases like rheumatoid arthritis. The project is in collaboration with Samar Moussa and John Liggio, research scientists at Environment & Climate Change Canada. Abdul-Sater’s co-applicant was York U biologist Gary Sweeney in the Faculty of Science.

Hosale’s project, “SensingChange: Black carbon air pollution detection and critical artworks,” will study airborne black carbon pollution by combining art, science and engineering to create new sensors on wearable devices that can detect the invisible particulate matter. Part of the project will include public art events where people can wear the sensors and learn more about the pollution levels in their area. Hosale’s project is in collaboration with several York researchers, including: Gerd Grau (his co-applicant) and Mark Gordon in the Lassonde School of Engineering; Joel Ong in the School of the Arts, Media, Performance & Design; and Enamul Prince in the Faculty of Liberal Arts & Professional Studies.

The York U research projects were among 133 projects from universities across Canada to receive NFRF’s Exploration Grants, announced last month.
