Adjunct professor in the faculty of engineering and architectural science Mark Ernsting was killed on McGill Street on Tuesday.

Interim Ryerson president Mohamed Lachemi notified the community in an email this afternoon.

“The victim of the fatal stabbing on McGill Street last night was Mark Ernsting, an adjunct professor in our Faculty of Engineering and Architectural Science and a biomedical engineer with the Ontario Institute for Cancer Research,” wrote Lachemi.

According to Toronto Police Services the suspect, 21-year-old Calvin Michael Nimoh, has been charged with second-degree murder. Nimoh was caught within an hour of the incident last night.

The Ontario Institute for Cancer Research released a statement following the incident on Twitter this morning. “We are deeply saddened at the passing of Mark Ernsting — a talented researcher and terrific person. Our thoughts are with his loved ones,” the post read.

Ernsting started teaching at Ryerson since 2013. He worked with graduate students in the electrical and computer engineering department and collaborated with faculty to advance cancer treatment innovations. He also spent four years working as a senior biomedical engineer at the Ontario Institute for Cancer Research. His research focused on nano medicines designed to deliver drugs directly to a tumor and relieve the negative effects of chemo therapy.

Ryerson Integrated Risk Management is currently working with Toronto Police Services to ensure the campus’ safety.
