I am a final-year PhD candidate in the School of Computing at the National University of Singapore (NUS), advised by Prof. Mun Choon Chan. My doctoral research tackles the systems challenges of deploying and operating virtualized Radio Access Network (vRAN) workloads.

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), Universiti Malaya, Malaysia, with my senior-year thesis advised by Prof. Teck Chaw Ling.

Research interests: I am broadly interested in systems and networking, with research spanning cellular networks, data center networking, and AI network infrastructure.
