Biography

I am an expert in physics-based modeling of nanoelectronic and magnetic devices for energy-efficient computing and communication. The models I create are predictive in nature, provide guidance to experiments, reduce costs of test-structures, improve the turnaround and success rate of laboratory tests by preventing trial and error, and enable correct interpretation of experimental data. I have been actively disseminating the simulation programs I develop via the open-source platform, nanoHUB, since 2013. The purpose of my computational outreach is to strengthen the innovation loop between materials scientists, device engineers, and circuit designers and eventually enable new functionalities in the next-generation sensing, memory, computing, and communication technologies.
