About me

I am a PhD candidate at the Center for Cybersecurity, New York University (NYU), advised by Prof. Brandon Reagen. I’m broadly interested in cryptographically secure privacy-preserving machine learning (PPML) and work at the intersection of deep learning and applied cryptography (homomorphic encryption and multiparty computation) as a part of DPRIVE projects. My research primarily focuses on developing innovative architectures and algorithms to optimize neural network computations on encrypted data.

In my early PhD, I worked on designing nonlinear-efficient CNNs and developed ReLU-optimization techniques (DeepReDuce, ICML'21), and proposed methods for redesigning existing CNNs (DeepReShape, TMLR'24) for end-to-end private inference efficiency.

My current research focuses on the privacy and security of large language models (LLMs). Specifically, I am investigating the role of nonlinearity in GPT models (Our preliminary findings, ATTRIB@NeurIPS'24), aiming to develop innovative methods for designing GPT models with fewer nonlinearities for efficient private inference.

I have also served as an invited reviewer for NeurIPS'23 and ‘24, ICLR'24, CVPR'24, and ICML'24. If you are interested in collaborating, please feel free to email me!
