I am a PhD candidate in the School of Computing at the National University of Singapore (NUS), advised by Prof. Mun Choon Chan. Before my PhD studies, I was a Research Assistant at the NUS-Singtel Cybersecurity R&D Laboratory working closely with Dr. Levente Csikor, Dr. Dinil Mon Divakaran, Prof. Jialin Li and Prof. Min Suk Kang.
Prior to joining NUS, I did my undergraduate studies at the Faculty of Computer Science and Information Technology (FCSIT), University of Malaya, Malaysia, with my senior-year thesis advised by Prof. Teck Chaw Ling.
My CV can be downloaded here (Last Updated: Oct’24).
My research focuses on systems support for emerging 5G/6G cellular networks. Additionally, I am broadly interested in software-defined networking (SDN), programmable data planes and data center networking (e.g., network support for distributed AI/ML clusters).
