Introduction
I am currently a Research Collaborator at Meta Platforms Inc., where I work on building next-generation network infrastructure to support human–GenAI interaction (launched in Meta’s core applications, such as Meta AI, WhatsApp, Instagram, and Messenger). I am completing my Ph.D. in Computer Science, luckily advised by Dr. Bo Han. Before that, I earned my B.S. degree in Computer Science in 2021.
My current research focuses on building large-scale, learning-based, real-time intelligent networked systems for emerging communication paradigms such as immersive telepresence and human–GenAI interaction. I also have extensive experience in security & privacy and human-computer interaction (HCI).
I have been the first author of several papers on a wide range of topics published in top-tier conferences, including bandwidth-conserving immersive telepresence (ACM SenSys 2024), privacy-preserving user authentication in VR with federated learning (ACM SenSys 2024), network measurement study on commercial social VR (ACM IMC 2022), immersive telepresence (ACM IMC 2024), real-time GenAI calling (ACM IMC 2025) platforms, and the deployment of a real-world VR-based online education system (IEEE VR 2024). I received the Best Paper Award from IEEE MetaBuild 2022 and the Best Paper Runner-up Award from ACM SenSys 2024.
