Prof. I. Leito is a very active and successful scientist, educator, leader of his research group. He is the programme director two international master-level study programmes that have been launched under his leadership.

Dr. Irina Shtangeeva is senior researcher at St. Petersburg State University, Russia. Her main scientific interests are biogeochemistry of trace and ultratrace elements, phytoremediation of contaminated soils and multivariate statistical analysis.

Recently Dr. Shtangeeva paid main attention to short-term variations in concentrations of macro- and trace elements in plants and rhizosphere soil that are due to circadian rhythmic changes and effects of interrelations between root exudates of different plant species on uptake of elements. She published more than 50 indexed publications, three books, two chapters book.

Markéta Holá received her PhD in chemistry from the Masaryk University, Brno, Czech Republic in 2004. Then she continues her carrier as a researcher and specialist in the field of Laser Ablation with Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) at the group of prof. Viktor Kanický at Masaryk University. 2014 - 2018 she worked in the research group of Synthesis and Analysis of Nanostructures in Central-European Technology Institute, Brno. From 2019 she works at the Department of Analytical Chemistry, Masaryk University. Her current research interests are mainly focused on the study of laser-sample interaction processes, study of laser generated aerosol, trace analysis of geological materials and imaging methods.
