Xin Zhe Khooi | National University of Singapore

About Me

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: Apr’24).

Research Interests

My research interests lie in the domain of programmable networks, particularly in exploring new applications/ use cases/ design paradigms with programmable data planes and software-defined networking (SDN) in cellular and/or data-center networks.
