Research Statement

I am very excited to design, construct and test implantable bioelectronic systems and intelligent sensor interfaces that are equipped with wireless energy harvester. Our systems are meant for neural prostheses, rehabilitation, seismic sensing, and gas sensing applications, which are validated through a variety of practical studies. We do have a strong collaboration with well-known universities in India, Singapore, and USA.
