I studied at the University of Veterinary Science (Budapest). My BSc thesis topic was “The frequency of re-nesting in the forest and urban populations of Great Tit” and I wrote my MSc thesis on the topic of “Annual survival of adult Great Tits in different types of breeding habitat”. Recently, I am a PhD student at the University of Pannonia, Veszprém. My study focusing on population viability and built population demographic model. Thus, we investigate the key demographic parameters as breeding-density, multi-brooding propensity, and survival probability.
