Marc D. Feldman, M.D.

Feldman lab 2 cropped


Dr. Marc Feldman is working on developing novel instrumentation in collaboration with faculty at the School of Engineering at the University of Texas in Austin.  These instruments are often commercialized for use in animals and patients including Admittance to measure left ventricular pressure volume relations, and Optical coherence tomography to determine the composition of atherosclerotic plaques.
