I am an Assistant Professor in the Department of Electrical and Computer Engineering at Boston University, where I co-direct the Security Lab (SeclaBU). Between 2014 and 2018 I was faculty in the Departments of Computer Science and Security and Crime Science at University College London (UCL). I am part of the International Secure Systems Lab and the iDRAMA Lab, I am an affiliated faculty in the Computer Science Department at BU, a Junior Faculty Fellow at the Hariri Institute for Computing, and a visiting faculty in the Information Security Group at UCL.
I was awarded an NSF CAREER Award in 2020, a Facebook Secure the Internet Grant in 2018, a UCL BEAMS Future Leaders in Engineering and Physical Sciences Award in 2016, a Google Research Award in 2015, the Outstanding Dissertation Award from the Department of Computer Science at UCSB in 2014, and a Symantec Research Labs Graduate Fellowship in 2012.
In my research I apply a data-driven approach to better understand malicious activity on the Internet. Through the collection and analysis of large-scale datasets, I develop novel and robust mitigation techniques to make the Internet a safer place. My research involves a mix of quantitative analysis, (some) qualitative analysis, machine learning, crime science, and systems design.
As examples, recently I have been investigating the spread of alternative news and memes on online social networks, raids organized by trolls against other Internet users, cyberbullying, ransomware, online dating scams, money laundering schemes linked to cybercrime, malware delivery networks, and online social network compromises.
My research is supported by the NSF, Google, and Facebook.
