I am interested in developing software infrastructure solutions for mobile and ubiquitous computing applications. My current research focuses on context-awareness and privacy preservation in mobile systems.

Over the past several years, I developed the first indoor localization system based on GSM fingerprinting that achieves a median accuracy of 4 meters and worked on enabling spontaneous and secure communication between mobile devices based on the knowledge of the common radio environment. My even earlier work dealt with improving performance in Mobile Ad Hoc Networks (MANETs). Specifically, I focused on alleviating self-interference between communicating nodes, dealing with the hidden terminal problem, and designing a cross-layer service discovery protocol for MANETs.
