Prof. Ranjit Thapa did his Ph.D. from Jadavpur University, Kolkata, India in 2011. He worked as a postdoctoral research associate at Indian Association for the Cultivation of Science (2011-2012), and as a postdoctoral fellow at Ulsan National Institute of Science and Technology, South Korea (2012-2013).

He joined SRM Research Institute, SRMIST as Assistant Professor in the year 2013. In the same institute he served as an Associate Professor during the year 2017 to 2019. He is an Associate of Indian Academy of Sciences (2016-2019). He is awarded with DAE-BRNS Young Scientist Research Award in the year 2018. He is an active member of Asian Consortium on Computational Materials Science (ACCMS). Three students have completed their Ph.D. under his guidance. He has four major projects under SERB-DST, BRNS, and MNRE. Prof. Ranjit Thapa has joined the Department of Physics, SRM University-AP, Amaravati in May 2019 as a Professor.

The research works of Prof. Ranjit Thapa are primarily focused on the first-principles investigation of materials for energy and the environment. The important contributions are “Exchange mechanism for spillover of hydrogen” and “dehydrogenation of hydrogen”. The main contributions are: “Bond exchange spillover mechanism”, “electron-doped 2D system as a metal free catalyst”, “the origin of surface magnetism in graphene”, “Homonuclear boron bond at the catalytic and active center”. Prof. Ranjit proposed Thin oxide overlayer (ex: MgO) on a metal surface, an inverse catalyst. The mystery behind the reactivity of doped defective graphene-based metal-free electrocatalysts is unveiled using density functional theory. The enhanced activity is linked to the π orbital occupation of active sites, the configuration of atomic oxygen (enolate and epoxy) on the graphene plane and to the localized π states in the case of defects. The π orbital occupation is identifying as “Descriptor”. Prof. Ranjit is currently interested in designing and developing of materials database for energy and environmental applications. His current goal is to apply the method of machine learning on the DFT data available in the web-based database https://energymaterials.org, to solve the energy and environment problem in a more efficient way.
