Hana Grison

Dr. Hana Grison, nee Fialová, (1974) works as researcher at the Institute of Geophysics CAS since 2001. She partly completed her doctoral studies (2001-2005) in France, in the laboratories of LGIT (CNRS/UJF) in Grenoble and in the laboratories of CEREGE (University of Aix-Marseille III). She obtained her Ph.D. degree at the Department of Applied Ecology, Faculty of Civil Engineering, Czech Technical University, Prague, defending Thesis entitled “Magnetic Discrimination between Lithogenic and Athropogenic Minerals in Soils”.

She focuses on interdisciplinary research bringing together geophysicists, archaeologists, and soil scientists, including geochemists with the overall goal of maximising interpretation of proxy data for archaeological purposes. She also specializes in strongly magnetic soils, including their geochemical properties. The goal of this research is to contribute to a better understanding of soil-forming processes and to use this knowledge, for example, to detect pollution by atmospheric fallout from industrial combustion. She is developing a method of archaeomagnetic dating in the Czech Republic. In scope of the program of the Academy of Sciences Strategy AV21, she deals with the magnetic recording of lightning in rocks.
