About Me
I hail from a small town called Agartala in northeast India. I grew up in a Bengali-speaking community surrounded by 19 tribal groups from Tripura, India. The strong relationships I developed with my peers during my school years are still something I treasure greatly. I completed my schooling from Ramakrishna Mission Vidyalaya, Amtali (Agartala, Tripura, India), securing a 91.4% in the higher or senior secondary education exam (AISSCE) held by CBSE, India. After finishing my schooling (2011), I joined the Electrical Engineering undergraduate program at one of the Institute of National Importance, National Institute of Technology, Agartala. Here, I was exposed to Photonics as an open elective in the 7th Semester of the program. It instantly captivated my interest, which led me to focus my B.Tech final project on non-linear optics. After completion of B.Tech in 2015, and securing a CPI (Cumulative Performance Index) of 9.00/10.00, I made up my mind to go for higher studies and joined the prestigious Direct Ph.D. program in one of the premire and prestigious institutes of India, IIT Kanpur. I developed a scalable fabrication technique for photonic elements using colloidal nanoparticles during my Ph.D. research period, under the guidance of Dr. Shilpi Gupta. Although my experiments and research work was halted and delayed several times due to COVID-19, I was able to complete my Ph.D. by 2022. After my Ph.D., I joined IISc Bangalore, as a post-doctoral researcher where I have currently been involved in developing sensors based on 2D TMDs, graphene, and Plasmonic structures, under the supervision of Professor Abha Misra.
In my free time I like to paint, write, and travel to remote locations carrying a camera. My father, now a retired bank manager, used to get Leave Travel Concession (LTC) during his active years. I was fortunate enough to visit 21 out of 29 states of India during his employment period, which built up the explorer in me and taught me to try new things.
I am probably looking at some weird clouds from the rooftop of Hall 8, IIT Kanpur 😅
