Professor Valeria Tsoukanova, a researcher and educator in 91ɫ’s Department of Chemistry whose work advanced the design of biomimetic materials for biomedical applications, passed away on April 11.
Tsoukanova joined 91ɫ in 2004 as an assistant professor, where she taught undergraduate and graduate courses in chemistry.
Tsoukanova’s teaching emphasized the relevance of chemistry to biological and medical challenges, connecting fundamental principles to real-world applications. Colleagues say she also had a gift for helping students grasp difficult material. “She approached teaching with exceptional care, thoughtfully preparing her lectures and presenting complex concepts in a way that students could understand and absorb,” says Professor Dasantila Golemi-Kotra, a colleague in the Faculty of Science.
This approach reflected a compassionate, attentive teaching style. She was always willing to offer guidance and encouragement, and remained committed to supporting her students’ academic and career aspirations.
Tsoukanova was also a respected researcher. “What distinguished Valeria as a researcher was her rigorous attention to detail and her unwavering commitment to fundamental scientific principles,” says Golemi-Kotra.
Her research focused on how extremely thin layers of molecules behave when they form on surfaces, similar to coatings on medical implants. She was particularly interested in how these molecules organize into membrane-like structures that mimic biological membranes. Her work advanced the understanding and design of biomimetic surfaces and materials, with applications in biomedical technologies including drug delivery systems and artificial membranes.
Her research, frequently supported by the Natural Sciences and Engineering Research Council of Canada (NSERC), helped guide the development of coatings that reduce protein buildup, allowing medical devices to function more reliably. It also informed the design of drug carriers that can move more effectively through the body. Together, this work contributed to the development of materials better suited for use in biomedical applications.
This integration of fundamental understanding and practical application defined her approach to research. “While pursuing a deep understanding of the mechanisms underlying molecular self-assembly, she consistently recognized the broader practical significance of this knowledge,” Golemi-Kotra says.
She sought to pass this perspective on to her students. According to Golemi-Kotra, Tsoukanova saw the training and mentorship of the next generation of researchers as an essential part of her scientific contribution and legacy.
Colleagues say this legacy extended beyond her academic contributions to her relationships with others. Positive, sensitive and unfailingly supportive, she offered encouragement to those around her. Golemi-Kotra and others will remember her for her intelligence, compassion and remarkable sense of humour, and for the encouragement she offered to colleagues and students alike.
