SUNIL KUMAR, Ph.D

About

Sunil Kumar is a postdoctoral researcher at the Hefei Institute of Physical Sciences, Chinese Academy of sciences (CAS) with a distinguished track record in the field of materials science. He possesses in-depth knowledge and expertise in CNT, TMDs, Graphene based gas sensors, noxious gas sensors. Kumar earned his Ph.D. in Materials Science from Samara National Research University, Russia, in 2021. His research endeavors have taken him to the Universidad Politécnica de Madrid (UPM) in Spain (Erasmus sholarship) and Novosibirsk State Technical University in Russia. During his postdoctoral tenure, Kumar has actively collaborated with the Skolkovo Institute of Science and Technology in Moscow, Russia, (only Russian university included in the TOP 100 Nature Index Young University*) to develop advanced noxious gas detection sensors based on graphene. Currently, Kumar is focused on developing LIG-based gas sensors and noxious gas sensors. Additionally, he is exploring the potential of LIBT (Laser Induced Backward Transfer) technology for transferring sensing materials onto glass substrates.
