Research interests include radiation effects in microelectronic devices and the study of radiation transport in devices. Specifically, using Monte-Carlo Geant4-based physics code to study the effects of nuclear reactions in emerging devices for accurate single event upset rate prediction; and studying basic mechanisms of single event effects for highly scaled technologies such as finFETs. Other research areas have included understanding radiation effects in 3D integrated circuits, single-walled carbon nanotube, and photoluminescent phosphor powders.
