I am an Associate Professor in the Computer Science and Engineering Department of the
University at Buffalo, The State University of New York. I received my PhD in Electrical and Computer Engineering at Purdue University
in August 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, LTE/WiFi coexistence, energy-aware protocol design for smartphones, and novel RF applications. I lead the UB Wireless Networking and Systems Lab ( UB WiNS Lab).
I received the UB Teaching Innovation Award in 2018, the NSF CAREER Award in 2016, the 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 Early Career Faculty Teaching Award in 2015.
07/30/2019: PhD openings in UB WiNS Lab for Spring 2020/Fall 2020 in topics related to millimeter wave networking and mobile apps (VR, video streaming) over 5G networks. I am looking for students with strong
coding skills (mainly C and Python) and good systems/networking background. Experience in any of the following is a plus: kernel programming,
wireless drivers, Android, wireless communications/PHY layer, signal processing, LabView. Interested students should apply online
and email me their CV.
07/12/2019: Paper accepted to ACM MobiCom 2019.
03/30/2019: Paper accepted to ACM MobiHoc 2019.
07/18/2018: Three papers accepted to ACM MobiCom 2018.
06/25/2018: UB Teaching Innovation Award.
05/01/2018: Joerg Widmer and I are organizing the 2nd ACM Workshop on Millimeter Wave Networks and Sensing Systems ( mmNets 2018), colocated with MobiCom 2018.
12/06/2017: School of Engineering and Applied Sciences Senior Teacher of the Year Award.
11/27/2017: Paper accepted to IEEE INFOCOM 2018.
11/16/2017: Best Paper Award Runner-Up in CoNEXT 2017.
10/20/2017: Best Paper Award Runner-Up in WiNTECH 2017.
09/07/2017: Paper accepted to ACM CoNEXT 2017.
02/15/2017: Domenico Giustiniano and I are serving as the General Co-Chairs of EWSN 2018 in Madrid.
