I am an Assistant Professor of Interactive Computing at Georgia Tech's College of Computing.

I direct the GT SPUD (Security, Privacy, Usability and Design) Lab. Our work, at the intersection of HCI, data science and cybersecurity, is oriented around answering the question: How can we design systems that encourage better cybersecurity and privacy behaviors? A few directions of particular interest to us at the moment include: making cybersecurity and privacy systems that are social; designing AI systems that subvert algorithmic surveillance; and, creating tangible / corporeal cybersecurity and privacy interfaces.

Here's a short (2.5 minute) video filmed by the CCC describing my social cybersecurity work. If you're interested in a more in-depth discussion, here's my 20-minute presentation at USENIX Enigma. If you want an even more in-depth discussion, here's my 45-minute job talk.

Since 2018, I have been serving as an associate editor for PACM IMWUT. I am also serving my fourth term as an associate chair for ACM SIGCHI: this year (2021) I am on the Understanding People subcommittee; previously, I was twice on the Engineering Interactive Systems and Technologies (2019, 2020) subcomittee, and once on the Privacy, Security & Visualization subcommittee (2018). I am also on the program committee for USENIX Sec '21.' For a full list of my professional service, please refer to my CV.

My work has been selected for a best paper award at UbiComp (2013), three best paper honorable mentions at CHI (2016, 2017, 2020), a distinguished paper award at SOUPS (2020), and an honorable mention for the NSA's Best Scientific Cybersecurity Paper (2014). I am a NDSEG fellow, a Qualcomm Innovation Fellow and a NSF EAPSI fellow. My work has also been covered by the popular press, including features on The Atlantic, The Huffington Post, Forbes, The Financial Times, Slate and other significant media outlets. My lab's work is generously supported by the NSF and Facebook. For a full list of honors and awards, please refer to the corresponding section on this webpage, or to my CV.

I have a blog and a vlog covering topics on academia and research in HCI and cybersecurity.
