David Klein


Associate Scientist, Li Ka Shing Knowledge Institute


I currently work in conjunction with Dr. Alexander Romaschin in the Department of Laboratory Medicine at St. Michael’s Hospital on the development and clinical application of novel biomarkers to acute care and critical care. I am also involved in the development of novel therapeutics targeting endotoxin in critical illness, as well as the linkage of diagnostics and therapeutics. Separately, I lead business strategy and partnerships for the Applied Health Research Centre (AHRC) and hold advisory roles to government and other policy makers regarding the healthcare system and business strategy.

Please note: Dr. Klein is not taking any summer students in 2018.
