Mitch A. Phelps, PhD is Director of the OSU Comprehensive Cancer Center Pharmacoanalytical Shared Resource, which supports pharmacokinetic (PK)/pharmacodynamic (PD) study design and conduct for pre-clinical and clinical drug development. Dr. Phelps has directed PK/PD studies in preclinical disease models and in early phase clinical trials for nearly ten years.  His research group focuses on development of small molecule and oligonucleotide anticancer and immune-modulatory agents here at OSU, using statistical modeling and simulation of PK/PD data to understand how genetic and other factors contribute to differences in therapy outcomes among individuals.  Dr. Phelps is an associate professor in the College of Pharmacy Division of Pharmaceutics and Pharmaceutical Chemistry and in the College of Medicine Department of Pharmacology.
