Short biography:

She was born in 1962 on Jesenice. After graduating from high school in 1981, she subscribed to the Department of Geology, NTF, University of Ljubljana. She finished her studies in 1987. She received her master’s degree from the same faculty in 1990 and her doctorate in geological sciences in 2002. In 1991 she received a Slovenian grant of Republiški sekretariat za raziskovalno dejavnost in tehnologijo (contract no. A64392618/90) for training at the McMaster University in Hamilton, Canada. Since 1987 she has been employed at the Karst Research Institute of the Scientific Research Center of the Slovenian Academy of Sciences and Arts. In the years 2004 to 2010 she was habilitated and additionally employed at the University of Primorska, FHŠ at the Department of Geography, and from 2010 to 2011 at UNG, Faculty of Postgraduate Studies, Department of Karstology. At FHŠ she lectured at the Undergraduate Program Geography of Contact Spaces, Karst Module (subjects: Fundamentals of Karstology (2006-2010) and Karst Geomorphology (2006-2010) and Geomorphology of Karst Surfaces and Caves (2010-2014). At UNG, Faculty of Postgraduate Studies of Karstology studies as an external lecturer in several basic and elective subjects. She was a member of the Scientific Council of IZRK ZRC SAZU from 2008 to 2012, and a member of the Scientific Council of ZRC SAZU from 2012 to 2016. She is a member of the Slovenian Geological Society (President from 2006 to 2010),  a member of the Geomorphological Society of Slovenia (President 2002-2007), and a member of SINQUA. She is a member of the International Speleological Union-UIS Bureau (2009-2017 Adjunct Secretary, and Treasurer since 2017) and a representative of the International Speleological Union-UIS at the International Council for Science (ICS) since 2017. She has been a member of the INQUA SACCOM and SEQ Group since 2018, and a member of the IUCN / WCPA Caves and Karst Group since 2018. She is a member of the editorial board of Acta Carsologica (since 2014 sectoral editor), and editor of various monographs and proceedings.


She is mainly engaged in the research and dating of cave sediments, geomorphology, and geology of karst, as well as the interpretation and promotion of karst and its science. She participates in karst and cave research around the world and lectures at conferences as an invited lecturer (e.g. Australia (MarieCurie IRSES project, 2010-2013), China (several bilateral projects, 1995-1996), Czech Republic (several bilateral projects, from 1997 onwards), Croatia (Interreg projects KUP and ŽIVO), Bosnia and Herzegovina, Indonesia, Brazil, Canada). Her bibliography comprises over 370 units.
