I am a Postdoctoral Researcher in the Computer Science department at the University of Illinois at Chicago. I am a member of the Systems and Internet Security Lab directed by Prof. Venkat Venkatakrishnan. I am currently involved in the MALDIVES (NSF) and MARPLE (DARPA) projects. I earned my Ph.D. in Computer Science from the University of Trento in 2013 under the supervision of Adolfo Villafiorita. I recieved my M.Sc. and B.Sc. degrees in Computer Science from Addis Ababa University.
My research interests include systems security (focus: Web, Mobile, APTs), cybercrime analysis (malicious sites/ads, exploit kits, ransomware), and data-driven security. My Ph.D. dissertation leverages honeyclient emulation and machine learning for effective analysis, characterization, and detection of web-borne malware. I have also developed defense and counter-offense techniques against exploit kits. Currently, I am focusing on systematic understanding of the end-to-end machinery of malware delivery mechansims on the Internet. I am also exploring intelligence-driven analytics to defend enterprise systems from targeted cyber-attacks.
