Robert M. Straubinger, PhD

Professor of Pharmaceutical Sciences
School of Pharmacy, University at Buffalo/State University of New York

DR. ROBERT M. STRAUBINGER is Professor of Pharmaceutical Sciences at the U/B School of Pharmacy. He holds adjunct faculty appointments in the Department of Molecular and Cellular Biophysics and Biochemistry and in the Department of Molecular Pharmacology & Cancer Therapeutics at Roswell Park Cancer Inst.. He also serves as Director of the Pharmaceutical Sciences Instrumentation Facility at UB.

Dr. Straubinger received dual B.A. degrees in English and Anthropology from the University of Rochester, the M.S. degree in Natural Sciences from the Roswell Park division of the University at Buffalo/SUNY, and the Ph.D. in Pharmacology from the University of California at San Francisco. He was a postdoctoral fellow in the Cancer Research Institute and in the Cardiovascular Research Institute at the University of California, San Francisco.

Dr. Straubinger's research focuses on the broad area of drug carriers and drug delivery, with an emphasis on the mechanisms by which drug carriers alter the pharmacology of carrier-associated drugs. The research approaches include biophysical investigations of the pharmaceutical properties of drug:carrier complexes, pharmacokinetic and pharmacodynamic analysis to probe mechanisms behind the therapeutic effects of drug carriers. A major new research direction is to develop proteomic approaches, principally based on liquid chromatography/mass spectrometry (LC/MS), to identify pharmacodynamic effect 'biomarkers' to assist in the development and optimization of therapies. Current research funding focuses on mechanisms by which drug carriers can modulate tumor vascular permeability.

Dr. Straubinger also serves as director of the Pharmaceutical Sciences Instrumentation Facility, which has facilities on the UB North Campus and the UB Center of Excellence in Bioinformatics and Life Sciences Downtown Campus.
