Research Scientist, Meta Reality Labs

 Incoming Assistant Professor, New York University 

About Me

I am working as a research scientist at Meta Reality Labs. Previously I was a postdoctoral fellow at Harvard University, and I received my PhD degree of Computer Science at the same university. Before coming to Harvard, I received my bachelor's degree and master's degree in Electrical Engineering and Statistics from University of Toronto.

 

My chinese name is 张赛骞.

 

I am incredibly excited to announce that I will be joining New York University in Fall 2024 as a tenure-track Assistant Professor of Electrical Engineering and Computer Science! I am looking for highly motivated PhD students and visiting students/researchers. Interested candidates are strongly encouraged to contact me by email, together with resume and transcripts.

Research Overview

Overall, my research interest lies in algorithm/hardware codesign for efficient deep neural network (DNN) implementation.

Application & Algorithm:

  • Efficient DNN computing, pruning, quantization, NAS

  • Recent interest: parameter efficient finetuning for LLM, efficient self-supervised learning, privacy for AI

Hardware architecture:

  • Domain-specific accelerator for compute-intensive AI applications, New compute paradigm for DNN

  • Recent interest: AI accelerator for on-device transfer learning and contrastive learning

Others:

  • Multi-agent reinforcement learning and its application

  • Federated learning

  • AI compiler
