Prof. Dr. Matjaž Kuntner is a senior research scientist at the National Institute of Biology and at the Research Centre of the Slovenian Academy of Sciences and Arts (ZRC SAZU), both in Slovenia, Professor of Zoology at the University of Ljubljana (Slovenia), a research associate at the Smithsonian Institution (USA), and a visiting professor at Hubei University (China). His research focuses on spider systematics, ranging from targeted species discovery and integrative taxonomy to phylogenetic analyses of morphological, behavioral, and molecular data, as well as biogeographic and phylogeographic analyses and phylogenomics. He also investigates interspecific and intraspecific (intersexual) coevolutionary patterns and their drivers, with an emphasis on interactions between sexual and natural selection in spiders, for example through studies of the causes and evolutionary consequences of extreme sexual size dimorphism, web gigantism, sexually antagonistic behaviors and morphologies, and kleptoparasitism. In addition, he studies spider ecology, species and clade distributions, biotic responses to global change, and the utility of DNA barcoding as a tool for species and higher-taxon identification. He mentors graduate students in Slovenia and China. He is the author of 180 scientific publications and serves as Editor-in-Chief of the journals Frontiers in Arachnid Science and Diversity.
