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. In the past, 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.
