I am currently working as Associate Professor at Department of Computer Science and Engineering,
Ghani Khan Choudhury Institute of Engineering \& Technology (A CFTI, under MoE, Govt. of India).
Before that I worked as Junior Professor at Universität Bielefeld, Bielefeld, Germany.
I also worked as an Assistant Professor at Department of Computer Science and Engineering, Aliah University,
Kolkata for 10 years. I worked as a stipend scholar (remotely from India) at Genome Data Science,
Universität Bielefeld, Bielefeld, Germany for six months.
Before that, I spent one year and two months at Life Science and Health group, Centrum Wiskunde and Informatica,
The Netherlands as an ERCIM (the European Research Consortium for Informatics and Mathematics) postdoctoral fellow.
I received Ph.D from Jadavpur University while working at Machine Intelligence Unit, Indian Statistical Institute,
Kolkata, India, where I spent one year and two months as a Junior Research Fellow. My research interests includes
deep learning model in single cell genomics, explanable AI, and big data systems in life sciences and health informatics.
