Professor, COMP SCIENCE, COMPUTING
Vice-Dean, DEAN-COMP, COMPUTING
Member of Technical Staff, Lucent Technologies, USA
Doctor of Philosophy, Columbia Univ, United States
Bachelor of Science with High Distinction, Purdue University, United States
I graduated with a BS in Computer and Electrical Engineering from Purdue University and Ph.D. from Columbia University.I was a Member of Technical Staff in the Networking Research Laboratory, Bell Labs, Lucent Technologies before joining NUS. I am currently a Professor in the Department of Compuer Science, School of Computing.
In Columbia, I was a member of the comet group and worked under the supervision of Prof. Aurel A. Lazar on large scale network emulation, network management and programmable network. In Bell Labs, I worked on network management and wireless data transport over cellular network. My work in Bell Labs includes highly cited work on TCP/IP performance over 3G wireless links (MobiCom 2012) and a US patent on cache-based compaction technique that has more than 200 patent citations (US Patent 6,178,461). My research interests cover sensor network protocols, mobile sensing, datacenter and programmable network. He has received best paper awards in IEEE ICNP 2019, ACM SOSR 2019 and ICDCN 2016 (networking track). He has also served on the Technical Program Committees of INFOCOM, ICNP, Sensys and IPSN. He has graduated over 20 PhD students, served as the Associate Editor of IEEE Transaction on Mobile Computing, published more than 100 conference/journal papers and has been awarded 7 US patents.

I am looking to supervise PhD students in the area of networked systems covering both data centers, 5G networks and mobile sensing.
I have broad interested in networked system research covering the following:
Programmable Networks: Research advances in Software Defined Networking (SDN) have enabled new paradigms and architectures through providing programmable capabilities to both the control and data plane. I am particularly interested in understanding how these capabilities enable new monitoring frameworks, control paradigms, virtualization strategies and speedup of large scale distributed computations.
Mobile Sensing: With mobile devices becoming ubiquitous, collaborative applications have become increasingly pervasive. We look into various approaches in which these devices can leverage the available sensing, computation and communication capabilities to design collaborative applications. In particular, we are looking at how high-fidelity context awareness can be achieved with low-cost sensing and communication on resource-constrained devices and possibly with collaboration among many different devices.
5G Network: 5G is expected to support a wide variety of users with very diverse requirements. We are looking at how a combination of Software Defined Networking (SDN), Network Virtualization (NV) and cloud computing can be used to meet the requirements of scaling, flexibility and isolation.
