Karin Lochte

Karin Lochte ( born 1952 in Hanover) is a German biologist and researcher. From 2004 to 2007 she was Professor of Biological Oceanography at the Leibniz Institute of Marine Sciences at the Christian -Albrechts -University of Kiel. There they conducted the research unit Biological Oceanography with emphasis biogeochemical cycles in the sea. Since January 2007 she has been Chairman of the Board of Governors of the Jacobs University in Bremen and since November 2007 she has been Director of the Alfred Wegener Institute in Bremerhaven.

Training

After her schooling in Hannover from 1959 to 1971 studied Karin Lochte 1971-1976 biology, chemistry and philosophy at the Technical University ( TU) of Hannover and graduated with the state examination for the Higher Teacher Training in Biology and Chemistry from. She then studied from 1977-1984 at the Marine Biology Marine Science Laboratories Menai Bridge in the University of Wales (Bangor, UK). They acquired the academic degree Master of Science ( MSc) in Marine Biology (1979) and Doctor of Philosophy (PhD) in Marine Biology (1985 ) with a thesis on " Microbiological observations at sea water discontinuities ".

Work

From 1985 to 1990 Lochte finished her time as a postdoc at the Institute of Oceanography at the University of Kiel with research on the microbial turnover of organic carbon in deep-sea sediments. After that she worked from 1990-1994 as a research associate at the Alfred Wegener Institute for Polar and Marine Research in Bremerhaven. Her research was about the microbial turnover of organic material in sea ice, water and sediment. In 1994, the Habilitation followed in Marine Biology / Aquatic Microbiology at the University of Bremen with the work " Microbial degradation of organic matter in the benthic boundary layer of the deep sea ." She then worked from 1995 to 2000 at the Leibniz Institute for Baltic Sea Research Warnemünde (Rostock) Director in the Department Biological Oceanography and professor at the University of Rostock for Biological Oceanography and Marine Microbiology in the research area Pelagic bacterial processes and nitrogen fixation. She was, from 2000 to 2007 at the Leibniz Institute of Marine Sciences at Kiel University, Head of the Research Unit Biological Oceanography and professor at the University of Kiel for Biological Oceanography. Her research area were the carbon and nitrogen fixation and microbial remineralization in the water column. Here, the tropical Atlantic was her special field of research. Lochte is a member of numerous national and international committees, including Since 1995, the Science Council. Since 2005 she has been a full member of the Academy of Sciences in Hamburg.
