My primary research interest is in the areas of unobtrusive and context-based authentication
factors, network security, wireless security, navigation and location technology, privacy and
security in loT systems, securing cyber-physical systems, location-based services, and privacy
and security in location-based services. Recent surveys show that most US adults use
smartphones. The current direction of digital systems is trending toward the user's mobility.
Thus, security in mobile networks is critical and I believe it's an important research subject. This
includes: studying contextual radiofrequency physical layer data and utilizing this data for
unobtrusive authentication, protecting wireless systems from attacks that manipulate wireless
messages, investigating algorithms to obtain location when using different wireless technologies
(e.g. GPS, Cell towers, Wi-Fi, Bluetooth, etc.), utilizing localization data for location-based
services' applications (e.g. Location-based access control). Furthermore, I'm interested in
studying location data security and privacy. This includes proposing privacy-preserving and
secure systems architectures. Moreover, my research interests include the area of mobile device
security from forensic and antl-forensic aspects. I believe this is an interesting research area that
combines different disciplines in computing.
