Ben Garcia joins Chemistry as Secondary Appointment

Professor Benjamin Garcia, Presidential Professor in the Department of Biochemistry and Biophysics in Perelman School of Medicine, received a secondary appointment in Chemistry. Ben received his B.S. in Chemistry from UC Davis, where he was an undergraduate researcher with Prof. Carlito Lebrilla and was first introduced to the field of mass spectrometry. He received his PhD in Chemistry from the University of Virginia under the supervision of Prof. Donald Hunt , and then was an NIH NRSA Postdoctoral Fellow at the University of Illinois with Prof. Neil Kelleher.

Research Interests: 

The Garcia Lab utilizes high-resolution mass spectrometry to explore cellular signaling, epigenetic mechanisms and chromatin regulation. We are especially interested in understanding how protein and nucleic acid modifications mediate their canonical functions and regulate nuclear processes. Mass spectrometry has become an unparalleled tool in the analysis of these biological molecules and allows us to obtain quantitative information about modifications as well as their co-occurrence. These modifications are critical for nuclear stability and transcription; and dysregulation of these pathways underlie several human diseases such as cancer. Our work aims to reveal the roles of these modifications in the cell cycle, proliferation, differentiation, signaling pathways and metabolism, to consequently help elucidate the mechanisms of various diseases.
