Profile

Ee-Chien Chang is an Associate Professor in the School of Computing at National University of Singapore. He received his PhD in Computer Science from New York University, and was a postdoctoral fellow with DIMACS in Rutgers University and NEC Labs America. His research areas cover information security, multimedia, and their intersection. His earlier works include image forensic, image watermarking and secure cryptographic techniques for noisy data. More recently, he has been investigating issues in data privacy and cloud security. He has published in reputable conferences and journals, including CCS, EUROCRYPT, USENIX Security, ESORICS, ACM Multimedia, INFOCOM, Journal of Applied and Computational Harmonic Analysis, etc. He is a lead-PI of the recently established National Cybersecurity R&D Laboratory in Singapore.
