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 research arena spans from ultrafast terahertz spectroscopy to micro and nano photonics.
