I am a young professional in Data Driven Cyber Security, currently a Ph.D candidate at the University of Maryland College Park. 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 cooking, bouldering, and photography. Check my Instagram page if you share the same interest!
