Hans Thewissen
JGM "Hans" Thewissen , complete Johannes Gerardus Marie Thewissen (born November 28, 1959 in Herkenbosch , Netherlands ) is a Dutch-American vertebrate paleontologist. He is particularly concerned with the evolution of whales .
Thewissen studied at the University of Utrecht with an intermediate diploma in 1981 and a diploma in 1984 and is a student of the whale paleontologist Philip D. Gingerich , with whom he received his doctorate in 1989 at the University of Michigan . As a post-graduate student , he was at Duke University Medical Center. He has been Assistant Professor since 1993, Associate Professor since 1999 and Professor of Anatomy since 2006 at Northeast Ohio Medical University.
In 2001 he was visiting professor at the Tokyo Institute of Technology. From 1994 to 2008 he was a Research Associate at the Cleveland Museum of Natural History.
In 1994 he discovered the primitive whale Ambulocetus in Pakistan .
In addition to the evolution of whales, he studies the evolution of manatees, primates, and bats and patterns of bone formation in the human skull. In the case of whales, he deals with adaptations of hearing and organs to life in water in the course of evolution. His laboratory examines morphological adaptations in the mammalian revolution with an interdisciplinary approach (palaeontology, anatomy, embryology, biology of the sensory organs, etc.).
He excavates a lot in the Eocene of India and Pakistan.
