Appointment Status

Dr. Paul Krzyzanowski is the Director of the Genome Research Platform, part of the Genomics Program at the Ontario Institute for Cancer Research. In this capacity, his group delivers state of the art genomics services for researchers across Ontario and Canada.

Since joining the program in 2016, Dr. Krzyzanowski has led the platform through several stages of growth and transformation towards a goal of laboratory accreditation by the College of American Pathologists, slated to be granted in early 2021.

In addition to this role, Dr. Krzyzanowski’s academic interests lie in the development of novel genome technologies and statistical techniques to analyze genomic data.

He is a co-inventor of SimSen-Seq, a patented technique used for ultra-sensitive mutation detection in cancer monitoring settings published in Nature Protocols.

Prior to this role, Dr. Krzyzanowski was a CIHR-funded Postdoctoral Fellow in the Informatics and Biocomputing Program at OICR. He also holds a MBA from the Rotman School of Management, University of Toronto, a PhD in Molecular Medicine from the University of Ottawa, and a BSc(Honours) from the University of Toronto.
