Overview

Professor Sarpeshkar's interdisciplinary research uses analog circuits and analog computation as a universal language to design advanced quantum, bio-molecular, and nano-electronic circuits and systems, from atom to living cell. These systems are experimentally implemented in living synthetic microbial DNA-RNA-protein circuits in his wet lab, and in nano-electronic supercomputing chips that emulate or are inspired by biological and quantum computation in his dry lab. His fundamental work has been applied to implantable medical devices, synthetic biology, systems biology, neural prosthetics, bio-inspired, and ultra-energy-efficient systems. His research group members have originated from a wide variety of disciplines including physics, bioengineering, microbiology, computer science, and analog circuit engineering.

Sarpeshkar is Dartmouth's inaugural Thomas E. Kurtz Professor and Chair of the Neukom Computational Science Cluster. He is a professor of engineering, physics, microbiology and immunology, and molecular and systems biology. His work has currently been cited over 13,000 times, his H-index is 54, and he holds 44 awarded patents. He has authored a leading textbook on analog circuits and bioelectronic systems. Prior to his joining Dartmouth, he was a tenured and award-winning professor at MIT.
