I'm an Assistant Professor at the University of Wisconsin-Madison in the Computer Science department. My goal is to enable society to gain the benefits of emerging technologies without the security and privacy risks. I have received two best paper awards (at IEEE S&P and IEEE SecDev) for my work in smart home security. My work has been featured in Wired, The Verge, Ars Technica, Science Magazine and Nature. I earned my Ph.D. in Computer Science and Engineering at the University of Michigan in 2017 where I was advised by Prof. Atul Prakash. Before coming to UW Madison, I spent two years working at the University of Washington as a research associate with Yoshi Kohno and Franzi Roesner.

I am always looking for students interested in computer security. If you are already a student at UW Madison feel free to email me. If you are a potential student, please apply to our MS/PhD program. Check out the MadS&P Research Group website for more information about security and privacy research at UW Madison.
