His research interests include the systematics and evolution of arachnids and other terrestrial invertebrates. He has published 374 scientific papers or books, and was instrumental in the promotion of short-range endemism https://en.wikipedia.org/wiki/Short-range_endemic_invertebrates through a paper outlining the criteria for recognising taxa that could be considered short-range endemics. His primary research interests are with Pseudoscorpions.
