She subsequently served as Chief Scientific Officer of Lakeside Discovery, a venture-backed biotechnology company spun-out from Northwestern University in Chicago, advancing academic innovations into therapeutic programs. Most recently, she was the Senior Director of Partnerships and Business Development at adMare BioInnovations, where she helped launch and grow biotechnology companies emerging from Canadian research institutions. She is also the co-founder of Block Biosciences and served as its inaugural Chief Executive Officer, leading the academic biotechnology spinout in the development of first-in-class oncology therapeutics.
