Sri Sarma receives National Science Foundation grant

September 27, 2011

Dr. Sri SarmaDr. Sridevi V. Sarma of the Institute for Computational Medicine (ICM) has

been awarded a National Science Foundation (NSF) Emerging Frontiers in

Research and Innovation award of $2,000,000 in support of the project

entitled “EFRI-M3C: Robust Decoder-Compensator Architecture for

Interactive Control of High-Speed and Loaded Movements.” The research

involves developing a novel model-based Robust Decoder-Compensator (RDC)

architecture for interactive control of fast movements in the presence of


The RDC is a feedback interconnection that decodes cortical signals to produce actuator commands that reflect motor intent, corrects for spurious signals generated by the cerebellum in the absence of proprioceptive feedback, and makes the interconnection to account for mismatches between models and reality more robust. A unique experimental paradigm will be exploited wherein neural spike and local field potential data will be collected from patients with implantable electrodes admitted for epilepsy surgery.

Dr. Sarma’s collaborators on the project are John Thomas Gale, Munther A. Dahleh, and Nitish Thakor. The award is effective September 15, 2011 and expires August 31, 2015.
