Dr. Mascha has led Biostatistical collaboration and research methodology for the Cleveland Clinic’s Anesthesiology Institute since 2005 and has over 25 years of experience as collaborative Biostatistician in perioperative medicine and various disease areas. His interests include design and monitoring of clinical trials, causal inference, inference on multiple correlated outcomes, mediation analysis, and complex equivalence and noninferiority designs. His current research involves expanding methods for analyzing composite endpoints containing binary, ordinal or mixed data types (see binary event design software), estimating heterogeneity of individual treatment effects using potential outcomes and mediation analysis for multiple mediators & outcomes. His journal publications are listed here.
