Research Interests 

My research interests include usable security and privacy, mobile and wearable computing and mobile health (mHealth) applications. I am currently working on privacy-preserving smartphone-based systems that leverage existing wireless transmitters (such as Bluetooth beacons, Wi-Fi access points) and allow smartphone users in spatio-temporal proximity (i.e., close encounters) to share information with each other. In the past, I have developed frameworks to collect provenance of mobile health information and conducted user studies and interviews to understand users' privacy preferences when using mHealth devices. Feel free to contact me (by email) if you are interested in problems related to usable security and privacy and mobile and wearable technology!
