I am an Assistant Professor of Interactive Computing at Georgia Tech's College of Computing. My work intersects HCI, data science and cybersecurity to invent novel, more socially compatible security tools that make end-user security less isolating and more likely to spread through social channels. I also occasionally work on other interesting topics broadly within HCI: including game personalization, mobile authentication, friendsourcing, and ubiquitous computing. I am a NDSEG fellow, a Qualcomm Innovation Fellow, a NSF EAPSI fellow, and a Facebook Fellowship finalist. My work has won a best paper award at UbiComp, two best paper honorable mentions at CHI, and an honorable mention for the NSA's Best Scientific Cybersecurity Paper. My work has also been covered by the popular press, including features on The Atlantic, The Huffington Post, The Financial Times, Slate and other media outlets. I received my Ph.D. from CMU's HCII where I was advised by Jason Hong and Laura Dabbish.
