Welcome to my homepage

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 an Associate Professor after the successful completion of the habilitation procedure in 2009 and 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 70 of them and I wrote eight college books for students as well. In SciVer SCOPUS, you can find cca 150 records regarding my results and I am first author in more than 45 cases with about 300 registered citations and h-index = 10. I am 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.
