I am a Senior Lecturer in the School of Computer Science and Engineering, UNSW, Sydney. My primary research interests are in applied cryptography, post-quantum cryptography, cybersecurity, blockchains and data privacy. I design practical, efficient and provably secure protocols that can be deployed in real-life applications. My interests are in critical infrastructure including smart grids and cloud, ad hoc networks and data sharing frameworks. As the world builds stronger capability in quantum technology, I am trying to design quantum safe algorithms to transition to a safer Internet. Recently, I have also been interested in ethical aspects of cybersecurity and legal and regulatory aspects around data sharing.
My aim is to carry out impactful research for the benefit of the society and mentor students to be critical thinkers and leaders. I love to work with my students and collaborate with the government, academia and industry. This has made research a very enriching experience for me. I have collaborated with researchers across five continents and have delivered over 80 technical lectures around the world. I have won several competitive grants like Samsung GRO Award, NetApp Faculty Fellowship, Cisco Academic Grant and IBM Research grant. I am a senior member of ACM and IEEE.
I am on the editorial boards of Elsevier Journal Pervasive and Mobile Computing (PMC) and Elsevier Journal of Information Security and Applications (JISA). I have served as Program Co- Chairs for ACISP 2021 and Indocrypt 2020. Besides, I have served on the program committees of many conferences like ACM ASIACCS, ACNS, ICDCS, IEEE ICBC, IEEE Globecom, IEEE ICC to name a few. I served as a member of the working group on “Blockchain For Cybersecurity” working group of the National Blockchain Roadmap of Australia and as a member of Trans-Tasman Initiative on Post Quantum Cryptography research.
Prior to joining UNSW, I was a Senior Research Scientist in CSIRO's Data61 (2019-2022) and Assistant and Associate Professor at Indian Statistical Institute, Kolkata. I started my academic career as an Assistant Professor at Indian Institute of Technology (IIT), Indore.
I completed a Ph. D. and Master's Degree in Computer Science from Indian Statistical Institute, Kolkata. My Ph. D. thesis was about Cryptographic Key Management. My Master's thesis was about Graph Ramsey Theory and got me an Erdos Number of 2. Many years ago, I was an undergradate student in Computer Science in Indian Institute of Science, Education and Research (Erstwhile B.E. College, Shibpur), the second oldest Engineering College in India.
I was born in Durgapur, a beautiful, quiet Indian city famous for its Steel Plant. I went to Carmel School, Steel Township and DAV Model School.
