About Me

I am an Assistant Professor at IIIT Hyderabad, India. Here, I'm associated with Centre for Security, Theory, and Algorithmic Research (CSTAR). I am a member of Ripple's UBRI and hold a Guest Researcher position at the SPRITZ research group at University of Padua, Italy. Previously, I worked as a Post-Doctoral Researcher in Delft Blockchain Lab of TU Delft, Netherlands (advisors: Prof. Zekeriya Erkin and Prof. Stefanie Roos). I was also a Visiting Research Scholar (host: Prof. Giuseppe Ateniese) at Stevens Institute of Technology, USA. I earned my PhD degree in Brain, Mind, and Computer Science (supervisors: Prof. Mauro Conti and Prof. Anna Spagnolli) from University of Padua, Italy with a fully-funded fellowship by Fondazione Cassa di Risparmio di Padova e Rovigo (CaRiPaRo). I also hold an MTech degree (supervisor: Prof. Manoj Singh Gaur) in Computer Engineering from MNIT Jaipur, India and a BTech degree in Information Technology from RTU Kota, India.

I have worked in different mainstream areas of research, including distributed ledger technology (blockchain and cryptocurrencies), networking (ICN and SDN), and AI (GAN-based password cracking). However, the main theme of my research has always been security and privacy. My research work is inherently multidisciplinary. Currently, I am focusing on the following research areas:

• Blockchain: Consensus and micropayments.
• Privacy: Anonymity and identity.
• Security: Communication and system.

I am motivated to learn, work upon, and teach new technologies in the field of computer science. I am always delighted to supervise strongly motivated Master's and PhD students, who are willing to work with me in my research areas (broadly, security and privacy). If you are interested, please drop me an email (with your CV).
