I am currently a doctoral student in Institute of Cyber Security, UT San Antonio, Texas, USA. My primary area of interest is cybersecurity, where we focus on access control models and implementation. Besides the foundational aspects of authorization, we apply our research in different domains including Internet of Things, Big Data and Cloud. We are presently focusing on vehicular IoT and connected cars as we believe this component is an integral part to realize the concept of Smart cities. Security and privacy should be embedded into this dynamic domain considering the serious implications such insecure systems can result.
