Ćavar Zeljković Sanja

Sanja Ćavar Zeljković, Dr. sc., dipl. eng. chem. (born 1980), has graduated in Chemistry at the Faculty of Science, University of Sarajevo, in Bosnia and Herzegovina. She defended her doctoral thesis in 2010 at the Faculty of Chemistry and Chemical Technology, University of Ljubljana, in Slovenia. In 2011 she was appointed the position of full-time Assistant Professor in Organic Chemistry and Biochemistry at the Faculty of Science, University of Sarajevo, and part-time Assistant Professor at the International BURCH University of Sarajevo, at the Faculty of Genetics and Bioengineering. Her research and teaching activities were mainly focused on the chemistry of natural products. During her research career, she made connections with other researchers worldwide, developing in these way successful collaborations that resulted in several related publications. In 2012, as an Erasmus Mundus scholar, she spent one month in the Laboratory of Natural Product Chemistry, at the Faculty of Science, Warsaw University in Poland. Since 2013, she is a Junior Researcher at the Centre of the Region Hana for Biotechnological and Agricultural Research, Palacky University. Her work is mainly focused on the isolation and identification of different classes of secondary plant metabolites and phytohormones, synthesis and examination of oxidation reactions of natural occurring and synthetic plant hormones strigolactones. While working on of the synthesis of strigolactones, in 2014, she had two 2-months stays at Radboud University Nijemgen, Faculty of Science, Cluster for Molecular Chemistry, in the Netherlands. Currently, she has more than 30 publications listed in Web of Science® and more than 50 participations in international conferences. Besides, her teaching activities at the Centre are in the fields of organic chemistry and phytochemistry.

Rozhenalová Monika

Monika Rozehnalová, Mgr., Ph.D., (born Jarošová, 1987) graduated from Faculty of Science, Palacký University in Olomouc in 2017 and obtained Ph.D. in Analytical Chemistry. The disertation thesis was entitled  Study of geochemical systems by ICP-MS with laser ablation. She spent three months long study visit in Warsaw, Poland in Ewa Bulska´s laboratory in 2014. Since September 2015 she has been working part time in Phytochemistry research group.

Kaczorová Dominika

Dominika Kaczorová, Mgr., graduated in Biochemistry at Faculty of Science, Palacky University in Olomouc in 2019. In the same year she started her Ph.D. study of Biochemistry under supervision of Sanja Ćavar Zeljković. Her work is focused on Cannabis genotypes characterization and its secondary metabolites profiling. She is competent in the analysis of natural compounds by liquid chromatography, gas chromatography and mass spectrometry.

Vrobel Ondřej

Ondřej Vrobel, Mgr., completed study of Biochemistry at Faculty of Science, Palacky University in Olomouc in 2019. His diploma work was focused on analyses of sulphur secondary metabolites produced by genus Allium and their subsequent enzymatic degradation. Current doctoral study is dedicated to influence of drought on the metabolism of a model plant, pea.

Bývalí zaměstnanci

Halouzka Rostislav

Rostislav Halouzka, Mgr. (born 1989), graduated from Faculty of Science, Palacky University in Olomouc, where he obtained M.Sc. in biochemistry in 2014. His master thesis was entitled Selected chemical methods of honey analysis. His PhD-studies are focused on the plant hormones strigolactones under the supervision of Petr Tarkowski. The objective of the work is a development of methods for isolation and puricifation of strigolactones from the plants. Moreover he studies strigolactone oxidative biotransformation by cytochrome P450 monooxygenases.

Jaworek Pavel

Pavel Jaworek, Mgr. (born 1987), graduated from Faculty of Science, Palacky University in Olomouc, in 2012 and obtained M.Sc. in biochemistry (his master thesis was entitled Development of method for analysis of hydroxylated cytokinin derivatives). As a postgraduate student he focuses his research on the clarification of biosynthesis of cytokinins with aromatic side-chain under the leadership of Doc. RNDr. Petr Tarkowski, Ph.D. In general, he deals with the sample preparation and analysis of small molecules from plants, beside cytokinins e.g. polyamines or phenolic compounds. For the analytical purposes, he mainly utilizes liquid chromatography and electrospray mass spectrometry. He also gained some experience in the field of plant tissue culture during his short-term research stay in Belgium (Gent).
