Short bio

I am a Principal Researcher in Hardware Security at Computing Systems Lab, Huawei Zurich research center since August 2021. my primary research focus is on trusted computing for large-scale distributed computing architecture and AI security. I received my Ph.D. degree in Computer Science in the System Security research group at ETH Zurich with Prof. Dr. Srdjan Capkun in 2021. My general research interest includes trusted paths, trusted execution environments, cyber-physical systems, and anonymous networks. Before joining ETH Zurich, I was a Research Engineer at Xerox Research Center India (now known as Conduent Labs India), Bangalore, in the data analytics research group. I led multiple research projects on privacy-preserving recommendation systems and designing systems for visually impaired people using wearable devices. I received my masters in Computer Science and Engineering from IIIT-Delhi.
