Sándor Laki, PhD
Assistant professor


I am an assistant professor at Faculty of Informatics, Eötvös Loránd University. 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.
