I am a PhD candidate at the Computer Science department of the University of Illinois at Urbana-Champaign. My work is conducted under the auspices of the Illinois Security Lab and the invaluable guidance of my advisor Professor Carl A. Gunter. My research focuses on Security and Privacy issues related to mobile devices. I have been studying side-channel and confused deputy attacks on the Android OS, privacy threats from mobile advertising, and access control designs and applications for smartphones and IoT systems.

 I believe mobility generates unique opportunities to advance humanity’s way of life. At the same time, it pushes attack surfaces beyond the traditional computer security boundaries. Mobile devices’ inherent always-with-us and always-on status, comes with non-trivial privacy implications. In particular, adversaries can take advantage of the advent of wearables, mobile application platforms and the internet of things, to launch sophisticated attacks aiming to compromise the devices’ integrity, users confidentiality ,and systems’ availability.

Bearing this new reality in mind, we need to revisit the way we think about system designs, essentially integrating security and privacy in the early design stages. Providing CIA guarantees without inhibiting utility and mobility advancements is my goal.
