The Department of Chemical Engineering & Applied Chemistry is deeply saddened to share the passing of Professor Emeritus Joseph C. Paradi on August 4, 2026. A distinguished alumnus, accomplished entrepreneur, respected scholar and dedicated educator, Paradi made lasting contributions to the University of Toronto, the engineering profession and generations of students.

Paradi’s connection to the department spanned decades. He earned his BASc, MASc and PhD in chemical engineering from the University of Toronto before embarking on a successful career in the rapidly emerging computer services industry. He founded Dataline, one of Canada’s pioneering computer services companies, and guided its growth through decades of technological change. He also served as president and chairman of the board of the Canadian Association of Data Processing Service Organizations (CADAPSO), held directorships with several high-tech companies and was actively involved in venture capital initiatives.
Born in Hungary on January 18, 1941, Paradi demonstrated remarkable determination from an early age. Introduced to skating at the age of two by his parents — Hungarian ice dancing champions — he went on to compete in junior hockey and became Hungary’s national speed skating champion for his age group. Following the Hungarian Revolution of 1956, he and his family fled their homeland and immigrated to Canada in 1957, where he went on to build a distinguished career as an engineer, entrepreneur, scholar and educator.
Paradi’s academic career at the University of Toronto spanned more than four decades. He joined the Department of Chemical Engineering & Applied Chemistry as an Adjunct Professor in 1983, before moving into a full-time academic appointment in Industrial Engineering in 1989 – with a cross-appointment in Chemical Engineering & Applied Chemistry. He was appointed Associate Professor in Industrial Engineering in 1991 and, in 1995, returned to Chemical Engineering & Applied Chemistry as an Associate Professor. In 1996, he was appointed full Professor in Chemical Engineering & Applied Chemistry, while also holding a cross-appointment in Mechanical & Industrial Engineering. Over the following decade, Paradi built an outstanding academic career, contributing through his teaching, research and mentorship before retiring in 2006 as Professor Emeritus. Even after his retirement, he remained actively engaged with the University, continuing to teach entrepreneurship courses, advise students and colleagues, and pursue his research.
His research focused on the measurement and improvement of productivity in service industries, particularly telecommunications and financial services, using data envelopment analysis (DEA). He published in leading journals, including the European Journal of Operational Research, IEEE Transactions on Engineering Management, OMEGA, and the Journal of Productivity Analysis, while contributing to numerous industry publications. He was an active member of several professional organizations, including IAMOT, INFORMS, and the Institute of Industrial Engineers (IIE).
Paradi was equally passionate about teaching and mentorship. Drawing on his extensive experience as both an engineer and entrepreneur, he inspired students to think beyond technical excellence and embrace innovation, leadership and business acumen. He founded the Centre for Management of Technology and Entrepreneurship (CMTE), creating opportunities for engineering students to develop the entrepreneurial and management skills needed to lead in an increasingly complex world. Throughout his academic career, he supervised 17 PhD students, 62 master’s students, seven postdoctoral fellows, five other researchers, and 186 undergraduate theses involving 254 engineering students. His influence extended far beyond the classroom through his mentorship, public speaking and commitment to preparing future generations of engineers for successful careers.

“I owe my academic career to Joe. He was a great mentor, colleague and friend. His enthusiasm for teaching and dedication to the students was second to none. Along with starting the CMTE and leading CERCL for many years, Joe became one of the preeminent researchers in Data Envelopment Analysis (DEA), in particular, the use of the methodology in bank branch productivity. His academic contributions in this field are substantial, which he culminated in the publication of a textbook. Joe will be missed, dearly.” – Professor Yuri Lawryshyn (ChemE)
“I think everyone in the department is aware of Joe’s enthusiastic and impactful contributions to chemical engineering. Joe was also, of course, the foundation of the entrepreneurial education ecosphere in our faculty. I was very fortunate to work with him in developing the Hatchery. His energy, positivity and love of teaching will be missed by many.” – Professor Emeritus Mark Kortschot (ChemE)
“Joe was one of the first people to reach out to me when I joined the department about 21 years ago, and I have always remembered that kindness. He was a true pioneer of entrepreneurial spirit, both in Canada and across the university, and his impact was remarkable. In his later years, I was also always struck by how supportive and encouraging he was toward my graduate students. That generosity meant a great deal to me and to them. He leaves a remarkable legacy and will be very deeply missed.” – Professor Milica Radisic (BME, ChemE)

In recognition of his outstanding contributions to the University of Toronto, Paradi was inducted into the University of Toronto Engineering Alumni Hall of Distinction in 2010.
Paradi will be remembered not only for his distinguished accomplishments in industry and academia, but also for his generosity, enthusiasm for teaching and unwavering commitment to student success. His legacy lives on through the countless students, colleagues, entrepreneurs and researchers whose lives and careers he helped shape.
We extend our heartfelt condolences to his wife, Monika, his children Joseph and David, and grandchildren Andrew, Laura, and Sophie, and all who knew him. He will be greatly missed by his family, friends, colleagues, former students and the broader University of Toronto community.
