About

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 assistants for security and privacy; exploring AR/VR to make security and privacy more engaging and accessible; and, making more usable developer tools that facilitate secure development.

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.

I am currently serving as an associate editor for PACM IMWUT. I have also served as an associate chair for ACM SIGCHI three times: twice on the Engineering Interactive Systems and Technologies (2019, 2020) subcomittee, and once on the Privacy, Security & Visualization subcommittee (2018). For a full list of my professional service, please refer to my CV.

I am a NDSEG fellow, a Qualcomm Innovation Fellow and a NSF EAPSI fellow. My work has won a best paper award at UbiComp (2013), three best paper honorable mentions at CHI (2016, 2017, 2020), and an honorable mention for the NSA's Best Scientific Cybersecurity Paper (2014). 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. I am also very fortunate to have been awarded a NSF CRII grant to support my work as a new investigator. 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.
