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 also the Lead Principal Investigator of the Singapore Cyber-security Consortium (2016-22), which is a consortium of 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. He has led 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 has served as an Associate Editor of IEEE Transactions on Software Engineering (TSE) during 2014-18. He is currently serving as an Associate Editor of IEEE Transactions on Dependable and Secure Computing (TDSC), ACM Transactions on Software Engineering and Methodology (TOSEM). His former doctoral students have been placed at universities all over the world as academics (Peking University, University College London, Monash, Shandong, SUSTech, SUTD) and have received various awards for their doctoral research including an ACM SIGSOFT Outstanding Doctoral Dissertation Award. Abhik received his own Ph.D. in Computer Science from the State University of New York at Stony Brook in 2000.

His research focuses on software testing and analysis, software security and trust-worthy software construction. His research on automatically repairing programs at a large scale contributes to the vision of self-healing software. Many of his recent research works have led to usage such as the research on program repair has been used for teaching of introductory programming via the Prutor system in India, and his research on fuzz testing in the form of the AFLFast tool has been integrated into the American Fuzzy Lop (AFL) fuzzer which is used by corporations for finding software vulnerabilities.
