Thomas Mock


Thomas is currently a faculty member at the University of East Anglia (UEA) in Norwich.


Before I came to the University of Washington, I obtained my Dr. rerum naturalis from the University of Bremen (Germany) at the Alfred Wegener Institute for Polar and Marine Research (AWI) in 2003 after graduating (Diploma) from the Kiel University (Germany) with a degree in Biological Oceanography in 1998. I have subsequently done postdoctoral work for 2 years at the AWI. My research topics are acclimation and adaptation of marine and particularly polar sea ice diatoms to their extreme environmental conditions (link). My postdoctoral work here at the Department of Oceanography in the group of Ginger Armbrust is related to genome wide expression analysis with the marine diatom Thalassiosira pseudonana. We are intent to construct the first Microarrays for this diatom in order to identify transcription units, which are related to important environmental conditions such as excess light intensity, carbon dioxide limitation or iron limitation.
