Post-doctoral Researcher | kbarott@ucsd.edukatie

Dr. Katie Barott is a postdoctoral scholar in the Tresguerres lab studying coral physiology and symbiosis. Katie completed her BS in Zoology and her BS in biochemistry and molecular biology at Michigan State University. After graduating she moved to the Woods Hole Oceanographic Institution where she worked as a Research Assistant studying microbial oceanography. She then moved to San Diego to complete her PhD as part of the joint program in biology between UCSD and SDSU. Katie’s PhD work focused on the role of bacteria in competition between corals and benthic algae. 

Research Interests:

  • Coral physiology and pH regulation
  • Interactions between corals, benthic algae, and microbes
  • Response of reef organisms to human impacts, particularly ocean acidification
  • Metagenomics

Katie is interested in understanding how corals interact with other organisms on the reef, from fellow macro-organisms competing for space on the benthos down to their endosymbiotic algae and bacteria. Her current research investigates some of the molecular mechanisms that influence coral symbiosis with their algal endosymbionts, with a particular focus on the role of pH regulation. She is also interested in how environmental factors such as human activity affect coral interactions and survival on the reef.

Katie has been awarded the NSF Ocean Sciences Postdoctoral Research Fellowship (2012 – 2014), the NOAA Climate and Global Change Postdoctoral Fellowship (2012, declined), the Achievement Rewards for College Scientists Fellowship (2011), and the NSF GRFP (2007 – 2010).
