Biography

I have an interest in clinical epidemiologic techniques to evaluate the effectiveness of therapies in critical care. Current areas of interest include use and development of meta-analytic techniques, evaluation of treatments to treat acute lung injury, septic shock, and acute renal failure in intensive care unit patients.

Please note: Dr. Friedrich is not taking any summer students in 2017.
