Research

Fundamental investigation of materials and functional devices and applied system design have traditionally been treated as isolated focus areas. However, there is fertile scope for optimally bridging these two areas of research to develop effective, and often unconventional, solutions to practical problems. Based on this rationale, my research program has evolved with time to bring about an overlap between these two, often, isolated areas of research. 

My interests lie at the intersection of diverse research areas involving (a) fundamental investigation of structured/pattered material design, development of unconventional and facile fabrication methods, coupled processes in multiscale structures and functional materials and devices,  and (b) applied aspects of conceptualization and design of sensing and energy harvesting systems for next generation self-powered and intelligent systems.  

The practical context for my current research is based on the needs of ubiquitous sensing which requires the development of self-powered smart sensing systems for monitoring in a  variety of contexts - indoor industrial monitoring, biomedical monitoring, and outdoor environmental monitoring. The primary requirements of effective solutions in these areas involve the development of novel sensing methods, devices, and algorithms housed in self-powered packages. As such, I am involved in the development of sensing and energy harvesting devices and systems in optoelectronic, photonic, and electromechanical contexts. 

The goal of my research is to develop smart materials, devices, and systems with applications in optoelectronic, electromechanical, and biological sensing, and energy harvesting. While my research activity in the past was focused on explorative aspects of material and functional electronic device design, my current efforts uses the insights developed through fundamental approaches to  designing, architecting, and developing smart systems.
