Dr. rer. nat. habil. Angela Köhler-Günther

Curriculum Vitae:

Angela Köhler and her research group at the Alfred Wegener Institute (AWI), Helmholtz Center for Polar and Marine Research have been conducting research on diseases and carcinogenesis in marine animals caused by chemicals since 1998. Angela Köhler completed her doctorate and habilitation at the University of Hamburg and taught at Jacobs University Bremen from 2003 to 2015 as Professor of Cell Biology and Toxicology of Marine Animals. In addition to publishing over 140 scientific articles, she has supervised 21 diploma/master’s theses and 20 doctoral students and postdocs and is one of the outstanding scientists in environmental research with 44,000 reads and 6,000 citations.


The AWI has obtained patents for Angela Köhler´s inventions for the production of caviar from live sturgeon in 90 nations in the field of sustainable food production on the subject of “caviar without killing endangered sturgeon” by the end of 2023. In 2017, Angela Köhler and her partner Dr. Alexander Ziegler-Jöns (founder and Vice President of IUB and Jacobs University Bremen) founded the company AKAZIE GmbH & Co KG to support the AWI in patent licensing. As Senior Honorary Consultant, Angela Köhler advises the AWI’s technology transfer and the licensees in the implementation of the new processes for caviar production without killing in their aquaculture facilities on site and in a training camp in Germany. The establishment of a joint “CLASSY CAVIAR network”and for the exchange of experience and knowledge between licensees is currently being prepared.


She has developed medical test systems for the early detection of health damage in marine animals from different climate zones for international monitoring programs such as ICES – International Council for the Exploration of the Seas. Angela Köhler is a member of international committees for marine monitoring and biodiversity protection (ICES; WSCS; SETAC; German Marine Litter Association).

Since 2011, she has been working on the topic of the uptake and effects of microplastics in marine animals, demonstrating for the first time that microplastic particles penetrate the cells of important organs and accumulate in cell organelles. In the UN0 expert group GESAMP, she is involved in the preparation of the first report “Sources, Fate and Effects of Microplastics in the Marine Environment: a Global Assessment” 2015 and is active in ROTARY “End Plastic Soup”.
