I am looking to recruit motivated PhD students to join my lab for Fall'25! This will be a fully funded position! If you are interested in working with me, please send me an email at <kafle@usf.edu>.
I am an Assistant Professor in the Computer Science and Engineering Department at the University of South Florida. I completed my PhD in Computer Science from William & Mary under the advisorship of Prof. Adwait Nadkarni. I was one of the founding members of the Secure Platforms Lab (SPL).
My research seeks to understand the security and privacy risks in diverse consumer-oriented software systems (e.g., Internet-of-things or IoT, Android, Online Political Campaigning) and develop practical solutions to identify the threats and automate their prevention. Given the diverse and disjointed nature of these systems, the focus of my research is to formulate tractable, consumer-oriented security and privacy research questions, combine a range of well-established techniques to analyze and identify the problems, and finally, design and build tools to prevent such problems.
Over my research career, my work has identified and demonstrated novel attacks (CODASPY’19 Best Paper), identified the prevalence of security and privacy threats at a large scale (CCS’22, IEEE S&P’24), and built targeted security tools and frameworks (USENIX’18, USENIX’22, CCS’22, IEEE S&P’24).
