For description of different research projects in my group please visit the AIM Laboratory Web Page.

My research explores new frontiers in unconventional analog computing techniques using silicon and hybrid substrates. The objective is to approach fundamental limits of energy efficiency, sensing and resolution by exploiting computational and adaptation primitives inherent in the physics of devices, sensors and the underlying noise processes.
