Dr Silvestru earned his Ph.D in geology at the ‘Babes-Bolyai’ University 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 (see below), written one book (The Cave Book—see below) and co-authored two 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 CMI.
His areas of expertise include: Sedimentology of clastic deposits, stratigraphy of limestone terranes, general geology, karst genesis and functioning, cave climate and glaciology, show-cave assessment & designing, ore prospecting and exploration (surface and mining).
After becoming a Christian he quickly realized that the ‘millions of years’ interpretation, so common in geology, was not compatible with Genesis. ‘Once I became a Christian,’ Emil says, ‘I knew I had to “tune up” my scientific knowledge with the Scriptures.’
‘Although philosophically and ethically I accepted a literal Genesis from my conversion, at first I was unable to match it with my “technical” side.’
E-mail discussions with qualified creationist geologists, creationist books, Creation magazine and especially the Journal of Creation (formerly TJ) helped him realise what he calls two ‘essential things’:
Given exceptional conditions (e.g. the Genesis Flood) geological processes that take an extremely long time today can be unimaginably accelerated.
The Genesis Flood was global, not regional.
‘These factors were immensely important in my conversion and my Christian life. I am now convinced of six-day, literal, recent, Genesis creation. That doesn't mean that there are not still some unanswered problems, but researching such issues is what being a scientist is all about.’
He has over 30 years experience in climbing and spelunking, educating many young spelunkers and mountain climbing devotees as well as participating in mountain and cave rescue operations.
In January 2002 he immigrated to Canada from Romania with his wife and two daughters. In addition to doing research and writing for CMI, he now also on staff at CMI Canada as a Seminar Lecturer, and has written a number of articles for the Journal of Creation, Creation magazine and this website, and produced several DVDs.
