I am an Assistant 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 focus on high performance/power-aware protocol design and implementation, testbed prototyping,
network measurements, and novel wireless applications. I lead the UB Wireless Networking and Systems Lab ( UB WiNS Lab).
I received the NSF CAREER Award in 2016, the School of Engineering and Applied Sciences Early Career Researcher of the Year Award in 2015, and the CSE Early Career Faculty Teaching Award in 2015.
02/10/2016: I am co-chairing the First International Workshop on
5G Millimeter-Wave Channel Models collocated with IEEE GLOBECOM 2016.
02/17/2016: NSF CAREER Award.
02/10/2016: I am co-chairing ACM WiNTECH 2016.
12/10/2015: CSE Early Career Faculty Teaching Award.
12/09/2015: Invited to Serve on the TPC of ACM MobiCom 2016.
11/27/2015: Paper accepted to IEEE INFOCOM 2016.
11/17/2015: School of Engineering and Applied Sciences Early Career Researcher of the Year Award.
10/26/2015: Seminar talk at UC Davis "Enabling Fine-Grained Motion Detection on Commodity WiFi Devices using PHY Layer Information".
10/26/2015: Seminar talk at Purdue "Enabling Fine-Grained Motion Detection on Commodity WiFi Devices using PHY Layer Information".
09/14/2015: Technical Report on 60 GHz WLANs.
06/2015: Papers accepted to IEEE Transactions on Wireless Communications and ACM HotWireless 2015.
06/2015: Paper accepted to ACM Mobicom 2015.
06/2015: I am co-organizing the IEEE ICNP 2015 PhD Forum. Both beginning and senior PhD students are encouraged to submit their work.
