Research InterestsMy research focuses on computer security and privacy with an emphasis on usable security and human centered computing. A large body of my research has focused on privacy in the context of the Internet of Things ('IoT') and ubiquitous computing (where computers are 'everywhere' and not always accompanied by a display or keyboard), as well as social networks.My recent work is centered on privacy in the context of pervasive photography, where in this case digital cameras are 'everywhere' (e.g., as smartphones or wearable cameras), and photo sharing has become more socially networked. I am also examining how cameras as assistive devices can improve privacy for people with visual impairments. With smart voice assistants gaining popularity, I have begun to explore privacy in the context of audio and speech based interactions with these devices. In the past I was intrigued by 'accountable anonymity' (how do you hold an anonymous misbehaving user accountable for their actions when they are indeed anonymous?) and applying crowdsourcing to security problems. Visit the Privacy Lab's homepage for more information about our group's research.

I was privileged to know Poker Odds in Texas Hold'em? I do not recommend gambling, but it was a fun coding project in grad school.
