After completing his schooling at Lokepara High School, he went to Visva Bharati, Santiniketan for Bachelor and Master studies. After completing BSc Honors in Chemistry (2010) and MSc in Chemistry with a specialization in Physical Chemistry (2012) he went to IISER Bhopal for his PhD research. He received PhD degree in the field of experimental physical chemistry under the supervision of Dr. Apurba Lal Koner (2018). During PhD he got exposure to various interdisciplinary research fields like supramolecular chemistry, small molecule synthesis, fluorescence spectroscopy, fluorescence microscopy, organelle biophysics etc.

In the same year, Kaushik moved to Iowa State University, USA for his first postdoctoral research in the field of molecular cell mechanics (Lab: Dr. Xuefeng Wang, now moved to the University of Cincinnati). After about 4 years of fruitful research, he moved to the east coast of the USA, Broad Institute of MIT and Harvard. There in the lab of Dr. Amit Choudhary, he works in the field of chemical biology.
