Short Bio

• Dr. Euijin (Alley) Choo is an Assistant Professor at the Department of Computer Science at University of Alberta, Edmonton, Canada. Prior to joining U of A, she worked as an industrial researcher (postdoctoral) at Qatar Computing Research Institute, a research professor at Korea University, and a visiting assistant professor at University of Missouri, Rolla. She received her Ph.D from North Carolina State University under the supervision of Dr. Min Chi and Dr. Ting Yu in 2015. She also received her dual BS in Computer Science and Mathematics, and MS in Computer Science, at Korea University under the supervision of Dr. Heejo Lee. Her research interest sits at the intersection of security and big data analysis, focusing on AI-based cybersecurity solutions and adversarial attacks. More specifically, it includes security and information assurance in e-commerce, and anomaly detection in network traffic and enterprise logs. Her research has been published in top conferences such as IEEE Symposium on Security and Privacy (S&P), ACM SIGMETRICS, and Usenix Security. She is a PI on various grants supported by industry partners and funding agencies. Due to her broad expertise and the interdisciplinary nature of her research, she actively serves on Technical Program Committees and as a journal reviewer for prominent data and security conferences and journals such as Usenix Security, ACSAC, Euro S&P, and IEEE TKDE. During her research, she received Provost Fellowship from NC state University and Brain Korea 21 Scholarship from Korea Research Foundation. She was also an awardee of a few travel grants to attend major security conferences including ACM CCS and IEEE S&P. She is truly honored to be a recipient of the best paper award at DBSEC 2015.
