Vojtěch Jarošík has worked for Charles University in Prague, Czech Republic, as a professor of ecology since 2006. He teaches basic and advanced courses on ecology and agricultural ecology, and advanced statistical courses for M.A. and Ph.D. students of biology. He first began at Charles University in 1991 as a lecturer, and associate professor in 1994 for the Department of Zoology. He was also the head of the Department of Ecology from 2004-2010.

Prior to his employment at Charles University, Jarošík studied biology there and received his M.A. in 1983 and his Ph.D. in 1988. Throughout his educational career he worked as a research entomologist for the Research Institute of Crop Protection, Prague, and as a research fellow at the Institut National de la Recherche Agronomique (INRA) in Antibes, France. He has also worked for the Imperial College at Silwood Park, Centre of Population Biology at the University of London, U.K., for the School of Biological Sciences, University of East Anglia in Norwich, U.K., and for the Bio-Protection Research Centre, Lincoln University in New Zealand.

Apart from textbooks on population ecology and agricultural ecology, he has co-authored more than 100 research papers and book chapters on population ecology, integrated pest management, biological control of pests, and conservation of rare species. In the last decade, he has concentrated predominately on statistical analyses of invasive alien species. Within the last five years more than 40 papers on biological invasions (including several papers in PNAS, TREE and Ecology Letters), which he co-authored, generated more than 1,000 citations.
