Biography

My research follows two major themes: (1) health policy and (2) sepsis and critical illness.   In the area of health policy, I co-lead the Centre for the Evaluation and Optimization of Public Healthcare Finance at IHPME with Dr. Adalsteinn Brown.  We are focused on improving healthcare capital investment and evaluation with a multidisciplinary group of collaborators.   In the area of sepsis and critical illness, I lead several efforts to develop novel diagnostics and therapeutics.  I have particular expertise in healthcare innovation and commercialization in addition to clinical development strategy.

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