I am a young professional in Data Driven Cyber Security; I attained my Ph.D. degree at the University of Maryland College Park; and I am currently at Samsung Research, Korea. I enjoy finding hidden relationships from the underground economy and applying graph algorithms that could reveal these dependencies among the malicious entities. Besides research, my current interests include golf, piano, and photography.
