I am an Associate Professor at Northeastern University in the Khoury College of Computer Sciences. I joined Northeastern University in Fall 2016. Before that, I was a Consultant Research Scientist at RSA Laboratories, performing research in security analytics, cloud security, applied cryptography, and foundations of cybersecurity. I am the receipient of the Technology Review TR35 award for research in cloud security in 2011 and the recipient of the Google Security and Privacy Award 2019.

My recent research evolves around the field of “security analytics”, the application of machine learning and artificial intelligence in cyber security. I am interested in designing rigorous machine learning techniques for learning and predicting attacker behavior, detecting malicious infrastructures, and designing more effective defensive techniques. I am also interested in securing public clouds against emerging threats, while protecting tenants' privacy.
