I am currently a Research Fellow (postdoc), at the NUS-NCS Joint Laboratory for Cybersecurity and School of Computing, NUS hosted by Prof. Divesh Aggarwal. Before that, I was a Visiting Fellow at Chennai Mathematical Institute (CMI), located in Chennai, India (Oct'22-Dec'22). I finished my Ph.D. (Aug'2018 - Aug'2022) in Computer Science from CMI, where I was fortunate to be advised by  Prof. Nitin Saxena (IIT Kanpur).  During my PhD, I was supported by Google PhD Fellowship (2018 -2022). I obtained my master's degree in Computer Science (2016-18) and bachelor's degree in Mathematics and Computer Science (2013-16) from CMI.  Here is my CV (updated in July 2023). 

My Erdős number  is 3 (Paul Erdős -> Noga Alon  -> Sourav Chakraborty ->  P.D.).

I often pen down my thoughts mostly through poems  (both in Bengali and English).  Check my blog.
