Biography (Short CV, Long CV)

Abhik Roychoudhury is a Professor of Computer Science at the National University of Singapore. He is the Director of the National Satellite of Excellence in Trustworthy Software Systems at Singapore (2019-23).  He is currently leading the TSUNAMi research center (2015-20), a large five-year long targeted research effort funded by National Research Foundation in the domain of trust-worthy software. He is also the Lead Principal Investigator of the Singapore Cyber-security Consortium (2016-22), which is a consortium of more than 40 companies in the cyber-security space engaging with academia for research and collaboration. He has advised on secure and smart cyber-space in different capacities, including being an industry advisory board member of the London Office for Rapid Cyber-security Advancement (LORCA) since 2018.

His research focuses on software testing and analysis, software security and trust-worthy software construction. His research group has built scalable techniques for testing, debugging and repair of programs using systematic semantic analysis. The research on automatically repairing programs at a large scale contributes to the vision of self-healing software. He has been an  ACM Distinguished Speaker (2013-19). His research has been funded by various agencies and companies, including the National Research Foundation (NRF), Office of Naval Research (ONR),  Ministry of Education (MoE), A*STAR, Defense Research and Technology Office (DRTech), DSO National Laboratories, Microsoft and IBM. He has been a keynote speaker at several conferences, and has served in various capacities in the program committees and organizing committees of various conferences on software engineering, specifically serving as Program Chair of ACM International Symposium on Software Testing and Analysis (ISSTA) 2016 and General Chair of ACM SIGSOFT Symposium on Foundations of Software Engineering (FSE) 2022. He has served as an Editorial Board member of IEEE Transactions on Software Engineering (TSE) during 2014-18.
