I am interested in modeling and simulation of technologically relevant cross-disciplinary problems (see below) where electronic devices may find new applications. Our research is always defined by close collaboration with experimentalists and theorists from other disciplines – because most fruitful research are always inspired and grounded by experimental observation and often occurs at the boundaries of multiple disciplines.

**Nanoscale devices for energy conversion**.

Current projects address various issues related to Organic Solar cells, Perovskite based solar cells, optics of nanostructured devices, etc.

**Nanoscale devices for Healthcare applications**.

Current projects include design and optimization of novel nanoscale electronic biosensors for better sensitivity, faster response time, and better selectivity (for both in vivo and in vitro applications).

**Semiconductor device physics and reliability**.

Modeling and simulation of Organic electronic (e.g., OFET) and optoelectronic devices (e.g., OLED). We also look into reliability aspects of semiconductor devices (e.g., NBTI).

**Nanoelectromechanical systems (NEMS**).

NEMS based bio/chemical sensors, switches, and energy conversion devices.
