I have started working at the Institute of Rock Structure and Mechanics of the ASCR, v.v.i. (IRSM) in 1998, before I completed my master's degree at the Institute of Geochemistry, Mineralogy and Mineral Resources, Faculty of Science, Charles University in Prague. I continued my doctoral studies at the same institute, finishing the Ph.D. degree in 2008.
Currently, I work as a researcher at the IRSM. My focus were geochemistry and mineralogy of sediments, weathering and geomorphology of sandstones and salt crystallization. I was also active in the field of practical applications of other geochemical methods and approaches (e.g. XRD, FTIR, Raman spectroscopy, laboratory isotopic study, physical experiments with locked sands and friable sandstones, experience with salt weathering, experience with measurement of rock surface strength or rock surface moisture). While some part of my fieldworks was and is carried on in the Czech Republic (different sandstone areas), during my career I also worked in Jordan, Poland, Great Britain, Luxembourg, Germany, U.S.A. or France. At this time, I deal with the scanning electron microscopy – SEM and EDS (QUANTA 450, FEI) and with the experiments in the climatic test chamber (CTC 256, Memmert). I am author or co-author about 50 scientific papers, some reports, and served as reviewer for several student´s thesis.
Some other older works and projects were supported by cooperation with Dr. D.Hradil and Dr. P.Bezdička from the Institute of Inorganic Chemistry of the Czech Academy of Sciences, v.v.i. (XRD analysis). Some publications were created on the basis of cooperation with colleagues from the Institute of Chemical Technology, University of Chemistry and Technology, Prague (with Dr. D.Koloušek and with Ing. L.Herzogová or Dr. M. Novotná and Dr. Machovič – FTIR methods and Raman Spectroscopy). The collaboration on electron microscopy has been ongoing for the last years with some colleagues from the IRSM (Dr.M.Vondráčková and Dr.Šrein, Dr. L.Nováková or Dr. M.Černý). Foreign cooperation was supported in 2018 by the study of clay minerals using SEM and EDS with Dr. Javier Cuadros from the Natural History Museum in London.
In the last few years, I cooperated intensively with ass.prof. J.Bruthans from the Faculty of Science of the Charles University in Prague and with Dr. M.Filippi from the Institute of Geology of the Czech Academy of Sciences, v.v.i. This cooperation builds on previous studies on the issue of geomorphological development of sandstone rock towns, especially with ass.prof. Bruthans and his many students from the Faculty of Science, Charles University in Prague, with Dr. A.L. Mayo (Brigham Young University, Provo, U.S.A.) and with some other colleagues (Dr. J.Adamovič from the Institute of Geology of the Czech Academy of Sciences, v.v.i., ass.prof. G.Kletetschka from the Faculty of Science of the Charles University in Prague and Dr. J.Válek from the Institute of Theoretical and Applied Mechanics of the Czech Academy of Sciences, v.v.i.). In our current project, we focus on all granular rocks.
