Welcome to my OLD homepage - not updated since June 2017 

I was born in 1971 in Czech Republic, where I live. I graduated from Faculty of Electrical Engineering and Computer Science VSB-Technical University of Ostrava and I hold a doctorate degree in Telecommunications from the same faculty (FEECS). I received my Ph.D. in 2002 and the thesis dealt with  "Voice traffic optimization with regard to speech quality in network with VoIP technology". I was appopinted as Associate Professor based on habilitation procedure in 2009 and  I passed all procedural steps to be appointed Full Professor in 2017. Since 2013 I have been leading Department of Telecommunications in position of department chair at FEECS.

The focus of my research is on Computer networks, Next generation networks, Wireless networks, IP telephony, Security in networks,  Speech quality, Quality of services, BigData analysis and more or less I deal with everything regarding Communication technologies. I am author or co-author more than 400 publications and my publication activities correspond to research interests mentioned above, moreover I am single author more than 80 of them, I wrote nein college books for students and I am author of two monographs and three chapters in books. In SciVer SCOPUS, you can find cca 200 records regarding my results and I am first author in more than 50 of them with over 500 registered citations and h-index=12. I am an IEEE Senior Member of IEEE chapter Communications and IEEE Big Data Community, a member of editorial boards of several journals, many conference programme and steering committees and a founding member of IP telephony task force in the research intent of CESNET (the research group was established in 1999).  

I give lectures in VSB-Technical University of Ostrava and I lead the following courses:

I am married to Pavla, we have a son and two daughters.
