Abhishek Kumar

Dr. Abhishek finished his integrated BS-MS degree from IISER Kolkata in 2016. He obtained PhD in Physics and Applied Physics from Nanyang Technological University (NTU), Singapore in 2020. During the doctoral study, he discovered the elusive excitonic phase in two-dimensional perovskite materials that provide record efficiencies for light-to-electricity conversion in solar cells. His work demonstrated the application of excitons in designing an ultrafast terahertz modulator with 50 GHz modulation speed for emerging 6G communication. He did his postdoctoral research on “Silicon Topological Terahertz Photonics for 6G communication devices” at Centre for Disruptive Photonic Technologies (CDPT) Singapore.

He joined JNCASR as an Assistant Professor in August 2023. 

His Ultrafast Terahertz Spectroscopy and Photonics (UTSP) lab at JNCASR is primarily interested in unveiling the fundamental properties of emerging quantum materials, that hold promise for next generation quantum technologies. The research themes broadly cover two aspects of terahertz science and technology with a specific focus on (a) Spectroscopic Investigation of emerging quantum materials and (b) Micro-Nano photonics for disruptive applications.
