Jiřina Vejnarová was born in Plzeň, Czech Republic, in 1962. She obtained the RNDr. degree (corresponding to M.Sc.) in Probability and Statistics from the Faculty of Mathematics and Physics, Charles University, Prague, in 1986, and the CSc. degree (corresponding to Ph.D.) in Theoretical Cybernetics from the Czechoslovak Academy of Sciences in 1991.
She has been with the Institute of Information Theory and Automation since 1986; since July 2009 as the deputy director for research. In May 2017 she was appointed the director.
Jiřina Vejnarová’s research interest is in the field of structured multidimensional models in the framework of imprecise probabilities, particularly in possibility and evidence theories. She has authored (and co-authored) more than 50 research publications in these areas. She has been involved in several research projects (both Czech and international ones).
Since 1996 she has been teaching at the Faculty of Informatics and Statistics, University of Economics, Prague, and since 2008 at the Faculty of Nuclear Science and Physical Engineering, Czech Technical University (at present undergraduate courses on Theoretical Computer Science, Information and Inference Theory and Probabilistic Models of Artificial Intelligence). In 2011 she was appointed associate professor. Jiřina Vejnarová has been a member of numerous program and organizing committees at international conferences and personally organized the 5th International Symposium on Imprecise Probabilities: Theory and Applications ISIPTA’07 in Prague. She also co-chaired the program committee of this conference.
In 2003-2010 she was a member of the Board of Czech Society for Cybernetics and Informatics, she is also a member of the Editorial Board of the journal Kybernetika.
