Dr. Andrej Ernst is a specialist for bryozoan taxonomy, evolution, biogeography and ecology, as well as for carbonate sedimentology. His PhD at the University of Kiel (1999) was devoted Permian bryozoans of Zechstein Basin and NW Tethys. After a short post-doc project he spent one year at the Geological Museum in Oslo (2002-2003), then acted at the University of Kiel. In 2013 Andrej Ernst has moved to Hamburg. The range of his research includes study of Palaeozoic and some post-Palaeozoic bryozoans faunas worldwide.
