I am an Assistant Professor in the Department of Computer Science and Engineering, Indian Institute of Technology Bombay. Before joining IIT Bombay, I spent two wonderful years of postdoctoral research at NTU Singapore (Jan 2022 - Jan 2023; with Professor Thomas Peyrin) and UCLouvain Belgium (Feb 2023 - March 2024; with Professor François-Xavier Standaert). I completed my PhD from the  Department of Computer Science and Engineering, Indian Institute of Technology Kharagpur (Jul 2016 - Sep 2021) under the supervision of Professor Debdeep Mukhopadhyay and Professor Pallab Dasgupta. 

My primary area of research is Hardware Security and Cryptography. In my Ph.D. and postdoctoral research, I have worked on Fault Attacks for Symmetric-key cryptosystems and Post-Quantum public-key cryptosystems. I also work on Side-Channel attacks and other aspects of Hardware Security, such as microarchitectural attacks, Logic Locking, etc.  

Besides my research, I spend most of my leisure time reading books and travelling. 

I am actively looking for interested and motivated students. Please feel free to drop me an email if you are interested in my research area. Students from Electrical and Electronics backgrounds are also encouraged. I am especially looking for people with hardware design expertise. But that is just one area and not all. So please connect if you are interested. 

** I am looking for students in microarchitectural attacks, side-channel, or fault attacks, and Post-Quantum Cryptography. Please drop me an email if you are interested. For details on this topic, please take a look here. Alternatively, you can also browse through the accepted paper lists in the top conferences and journals: TCHES, IEEE TIFS, IEEE TC, IEEE TCAD, IEEE TDSC, ACM-CCS, S&P, EUROCRYPT, ASIACRYPT, CRYPTO, ToSC, DATE, DAC, ICCAD, HOST, HPCA.

** The entry process into PhD and MS programs is through qualifiers organized twice a year. Please check the CSE IITB webpage for the dates. However, if you are interested in doing research under my supervision, please email me beforehand with your CV and list of expertise.
