I am an assistant professor at Faculty of Informatics, Eötvös Loránd University, heading a small research group called Communication Networks Laboratory (CNL). CNL was originally established by Ericsson Research and ELTE, and we still work in close collaboration with various units of Ericsson. My research interests are the general topics of computer networking with special focus on traffic analytics, IP geolocation, application of software defined networking and language abstractions for programmable networking elements.
Recently, my research has shifted towards novel data plane solutions including network programmability and flexibe state-less resource sharing. You can read more about related projects on the project page.
