Interacting and extracting information from electromagnetic fields is one of the core foundations of all technologies that involve us interacting and understanding our environment. This extends right from detecting tiniest traces of proteins in body fluids to optical imaging to sending information via wireless communication. Our interest is in new ways extracting information from electromagnetic fields from RF-optical frequencies to enable new integrated and chip-scale technologies for communication and imaging to health and diagnostics.  Broadly my research interests are

1. Reconfigurable Millimeter-wave Systems, An and Electromagnetic Interfaces

2. Programmable Chip-scale Terahertz Systems

3. Nano-optical Systems and Biosensing
