I am a PhD candidate at the School of Computer Science in Georgia Tech working with Professor Milos Prvulovic and Professor Alenka Zajic. My research interest is on the broad area of Security and Privacy with emphasis on computer architecture, embedded/cyber-physical systems, side-channels, and hardware support for privacy-preserving and trustworthy AI/ML.
[Recent News] I'm joining the Electrical and Computer Engineering Department at UCLA Henry Samueli School of Engineering and Applied Science in Summer 2020 as an Assistant Professor. You can learn more about my research interests in [Research]. Please contact me if you are interested in working with me.
My research has been focused on improving the security and privacy of a wide range of systems- from modern computers to resource-constrained embedded systems. My work is interdisciplinary, spanning Computer Architecture, Security, Hardware Design, Machine Learning, Digital Signal Processing, and System design. The following describes them in more details. Please visit [Publication] for the latest list of my published papers.
Moving forward, I'm planning to continue my research in three main directions:
[January 2020] My side-channel simulator paper is nominated for Best Paper Award at HPCA-26. See [Publications] for more details.
[November 2019] Two papers are accepted at HPCA-26. See [Publications] for more details.
[October 2019] One paper is accepted at IEEE Transactions on Information Forensics and Security. See [Publications] for more details.
[October 2019] Selected as an RSA Security Scholar. Hope to meet you all at RSA-Conference 2020!
[September 2019] Serving as a Committee Member at EMC2 Workshop (Workshop on Energy Efficient Machine Learning and Cognitive Computing). The 5th edition is at NeurIPS2019. Send your best work!
[August 2019] One paper is accepted at MICRO-52. See [Publications] for more details.
[July 2019] Two journal papers are accepted at IEEE Transactions on Dependable and Secure Systems and Journal of Hardware Security (HASS). See [Publications] for more details.
[June 2019] Gave a talk at Accenture Cyber-Fusion Center, Washington DC, on novel methods for exploiting physical side-channels for malware detection.
Explored novel methods for trustworthy AI and privacy-preserving machine learning including designing and implementation of a homomorphic encryption framework. Also, investigated new defense mechanisms against privacy attacks such as Member Inference and Model Extraction.
Investigated new architectural techniques to improve the performance of a convolutional neural network accelerator using in-house cycle-accurate simulators (C++) and emulators (Python). Also, performed a Power-Performance-Area (PPA) analysis on RISC-V cores to systematically gain insights about the differences between RISC-V and the state-of-the-art ARM and MIPS in-order and OoO cores.
Mentored and advised 6 undergraduate students (shown in the following) at the Georgia Institute of Technology for three different year-long projects.
