Dr. Ben Leong is an Associate Professor of Computer Science at the National University of Singapore (NUS). He received his S.B. (1997), M.Eng. (1997) and Ph.D. (2006) degrees from the Massachusetts Institute of Technology. Dr. Leong’s research interests are broadly in the areas of computer networking and distributed systems. He has worked on a number of problems in the areas of sensor networks, network coding and peer-to-peer file transfers in the past. More recently, he has been working on improving communications for mobile cellular networks, TCP and software defined networks. Dr. Leong's teaching has been focused on teaching programming methodology and advanced software engineering to undergraduates. He was a recipient of many teaching awards at both the Faculty and University level. In 2015, he was awarded the NUS Outstanding Educator Award. He currently serves as a the Chair of the CS Department Standing Teaching Committee, where he coordinates the Department's efforts to improve the quality of teaching. Since July 2014, Dr. Leong holds the joint appointment of Director, Experimental Systems & Technology Lab. In this role, Dr. Leong helped to set up the in-house software development capabilities for the Ministry of Education. He currently leads a team of 20 full stack software engineers in the development of modern software systems for MOE using modern technologies like Ruby on Rails, Golang, React, Docker and Kubernetes.
