Sridevi Sarma received the B.S. degree in electrical engineering from Cornell University, Ithaca NY, in 1994; and an M.S. and Ph.D. degrees in electrical engineering and computer science from Massachusetts Institute of Technology, Cambridge MA, in 1997 and 2006, respectively. From 2000 to 2003 she took a leave of absence to start a data analytics company. From 2006 to 2009, Dr. Sarma was a postdoctoral fellow in the brain and cognitive sciences department at the Massachusetts Institute of Technology, Cambridge. She is now an associate professor in the Institute for Computational Medicine, Department of Biomedical Engineering, at Johns Hopkins University. Her research interests include modeling, estimation and control of neural systems using electrical stimulation. She is a recipient of the GE Faculty for the Future scholarship, a National Science Foundation graduate research fellow, a L'Oreal for Women in Science fellow, the Burroughs Wellcome Fund Careers at the Scientific Interface Award, the Krishna Kumar New Investigator Award from the North American Neuromodulation Society, and a recipient of the Presidential Early Career Award for Scientists and Engineers (PECASE) and the Whiting School of Engineering Robert B. Pond Excellence in Teaching Award.

Research & Publications
My research interests are centered in three key areas: closed-loop deep brain stimulation for Parkinson’s Disease (PD); closed-loop stimulation for epilepsy; and brain-machine interactive control of fast movements.
With respect to closed-loop deep brain stimulation (DBS) for Parkinson’s Disease, my focus is on the modeling of basal ganglia (in health and PD), the modeling effect of DBS, and feedback control design of DBS strategies.
Seizure detection from invasive EEG signals, and seizure foci localization from invasive EEG signals are central to analysis of closed-loop stimulation of epilepsy.
Brain-machine interactive control of fast movements entails the modeling of cerebro-cerebellar regions from human and primate data, as well as optimization the design of a decoder-compensator.
