Research Interests

My 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 '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. In the past I was intrigued by 'accountable anonymity' (how do you hold an anonymous misbehaving user accountable for their actions when they are... anonymous?) and applying crowdsourcing to security problems.

Keywords: Security and privacy in pervasive, mobile, and wearable computing (especially wearable cameras); usable security/privacy and HCI; privacy in social networks; accountable anonymity; crowdsourcing security

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