Dr. Bolger has worked with government agencies, non-government organizations, the private sector and local villagers to manage cave and karst resources for conservation and for ecotourism development. He is coordinating the geoheritage aspects of a World Heritage nomination for a karst National Park, and identifying and describing significant geoheritage features for a potential Geopark in another karst protected area, in central Laos.

Dr. Bolger has written technical reports and popular articles for books, journals and magazines about the caves and karst of Laos and Thailand. He has also given numerous presentations on this subject to a range of audiences, from community and school groups to government officials and international conferences. These experiences have provided him with a broad knowledge about the caves, the karst landscapes and their ecosystems, and the lifestyles and cultures of the people who live in these landscapes.
