Associate Professor Director of Graduate Studies and Internship Coordinator Computer Science and Engineering Department University at Buffalo, SUNY Address: 338 Davis Hall                Buffalo, NY 14260-2500 Office: 311 Davis Hall Phone: 716-6454733 Email: dimitrio@buffalo.edu

I am an Associate Professor in the Computer Science and Engineering Department at the University at Buffalo, The State University of New York. I received my PhD in Electrical and Computer Engineering at Purdue University in 2010. My dissertation was supervised by Prof. Y. Charlie Hu. Previously, I received my Bachelor's degree from the School of Electrical and Computer Engineering at the National Technical University of Athens (NTUA).

My research interests are broadly in experimental wireless networking and mobile computing, with a current focus on millimeter wave networking, high-bandwidth applications (VR, 360^o video streaming) over wireless networks, LTE/WiFi coexistence, energy-aware protocol design for smartphones, and wireless sensing. I lead the UB Wireless Networking and Systems Lab (UB WiNS Lab). I received the IEEE Region 1 Technological Innovation (Academic) Award in 2019, the UB Teaching Innovation Award in 2018, the NSF CAREER Award in 2016, the UB School of Engineering and Applied Sciences Senior Teacher of the Year Award in 2017 and the Early Career Researcher of the Year Award in 2015, and the CSE Senior Researcher of the Year Award in 2019 and Early Career Faculty Teaching Award in 2015.
