overview

Justin Weinbaum received his B.S. in Molecular Biology & Biophysics from Yale University in 2000. Under the mentorship of Dr. Robert Mecham at Washington University in St. Louis, and funded by a National Science Foundation Graduate Research Fellowship, he classified the elastic fiber component MAGP-1 as a new member of the matricellular protein family. Dr. Weinbaum received his Ph.D. in 2007 and joined Dr. Robert Tranquillo at the University of Minnesota. A NIH/NHLBI Ruth L. Kirschstein National Research Service Awardee, Dr. Weinbaum contributed key biological insight to the lab's projects in artery, valve, and heart patch tissue engineering. As an independent scientist, Dr. Weinbaum aims to understand how the native extracellular matrix directs cellular behavior and to develop new treatments for degenerative disease.
