His research interest is the modeling of nanoelectronic devices, genetic algorithm based optimization, and image processing. NEMO, the nanoelectronic modeling software built in his research group established the state-of-the-art in atomistic quantum transport modeling. NEMO is now being used at Intel for advanced transistor designs and commercialized. He published over 525 printed scientific articles that resulted in an h-index of 68 in Google scholar.
