Bhagirath Ghimire, Ph.D.

bhagirath ghimire

Dr. Ghimire is a post-doctoral researcher at PERL focusing on atmospheric pressure plasmas, biological applications of plasmas, and plasma surface interactions. He received his BS and MS in Physics from Tribhuvan University, Kathmandu, Nepal, and a Ph.D. in Low Temperature Plasmas from Kwangwoon University, Seoul, South Korea. Prior to coming to PERL, Dr. Ghimire was a Senoir Research Associate at Lancaster University in the UK where he conducted research on use of APPs on sterilization of bacteria and viruses. At PERL, he leads the APP research effort and works with collaborators in biology, agricultural science, food science, physics, and chemistry to study different biological and terrestial applications of APPs.
