Ann M. Stock, PhD

Ann Stock is Professor of Biochemistry and Molecular Biology at Robert Wood Johnson Medical School and Resident Faculty Member at the Center for Advanced Biotechnology and Medicine since 1991, also previously serving as Associate Director (2008-2012) and Interim Director (2013-2019). Dr. Stock’s research interests focus on bacterial signal transduction and the molecular mechanisms that allow cells to elicit adaptive responses to changes in their environments. She participated in the discovery and characterization of a fundamental two-component phosphotransfer mechanism, now known to mediate the majority of bacterial signaling. Structure-function studies in the Stock lab have established the three-dimensional folds and conserved features shared by hundreds of thousands of response regulator proteins. Her current research focuses on understanding how an unusual class of hybrid two-component systems (HTCSs) regulate utilization of dietary fiber in gut bacteria. Research in the Stock lab has been supported by the NSF, NIH MERIT and MIRA awards, and the Howard Hughes Medical Institute (1994-2011).
