Dr. Emil Silvestru answers some questions. He earned his Ph.D in geology in Cluj, Romania (where he has worked as an associate professor), in karst sedimentology including caves. (Karst is a term which initially referred to barren regions of mostly limestone and dolomite, noted for spectacular and distinctive landforms, and with substantial underground drainage features — caves, underground rivers, etc. It has come to refer more to the entire geosystem, above and below ground.)
A world authority on the geology of caves, he has published 41 scientific papers, written one book (The Cave Book) and co-authored two other books. He was, until recently, the head scientist at the world’s first Speleological Institute (speleology = the study of caves) in Cluj. Since 1997 he has been a full-time researcher and speaker with Creation Ministries International.
