Research Activity

In 1995, he finished his studies, but did not receive his doctoral degree until 1996 with his thesis The Bedding-Plane Impact on the Development of Karst Caves (An Example of Velika Dolina, Cave Škocjanske Jame). His main field of work involves the stratigraphic, lithopetrologic and microtectonic research of karst terrains, as well as the subjects of selective corrosion and erosion of carbonates, and the speleogenesis of karst caves as a part of an underground karst aquifer. He is a successful leader and member of international research programmes, within which he works with karst experts from Croatia, the USA, Cuba, Spain, Japan, Russia, Poland, Switzerland, Iran, Germany, Italy, the Slovak Republic, the Czech Republic, the People's Republic of China, United Kingdom, United Arab Emirates, France, Australia, Vietnam, etc. Since 1995, he has been researching Chinese Karst. He participates in and manages planning and construction projects on karst, which includes the issue of protecting the features of this area: since 1990 he has been participating in the planning and karstological supervision of motorway and railway construction.

He is author of the books Vpliv lezik na razvoj kraških jam (1996) and Paleoekološke značilnosti apnencev v okolici Škocjanskih jam (2014), co-founder, co-editor and co-author of the books Karst features discovered during motorway construction on Slovene karst (2007), Karst Rock Features, Karren Sculpturing (2009), South China Karst 1 (1998) and South China Karst 2 (2011), new edition Karstology and Develoment Challenges on Karst (2012, 2013), The Beka-Ocizla Cave System (2015), Cave Exploration in Slovenia (2016), Karstology in the Classical Karst (2020), and author several tens chapters in different other books and encyclopedias.

He is co-founder and co-developer of the first under graduate study program of karstology in Slovenia and co-founder and co-developer of the only doctoral study program at the international level.
