Zoltán Barta is an evolutionary biologist and behavioural ecologist. He is a Professor of Biology at the University of Debrecen and Head of the Department of Evolutionary Zoology. Zoltán has a wide ranging interest from social foraging, through parental care and cooperation to state-dependent life history theory. Through his research Zoltán tries to combine theoretical and empirical approaches. Currently, his work focuses on social organisation of bird flocks, gene expression regulation of parental care in a new model system, the Lethrus apterus beetle and theoretical investigation of parental care concentrating the origin of sex role differences. Zoltán had completed several postdoctoral fellowships at abroad and currently holds a Minjang Fellowship at the Fujian Agriculture and Forestry University, China.
