Dr. Derek Gray


  • B.Sc.: University of Windsor (Canada)
  • M.Sc.: University of Windsor
  • Ph.D.: Queen's University (Canada)
  • Postdoctoral training: University of California, Santa Barbara


Dr. Gray grew up in Canada and received his undergraduate and graduate education there. While working on his master's degree at the University of Windsor, he conducted research aimed at finding ways to prevent the introduction of invasive species into the Great Lakes. His Ph.D. research at Queen's University examined how small wilderness lakes on the eastern shore of Georgian Bay have recovered after being damaged by acidification (wet and dry acid deposition). In particular, he studied how organisms that were extirpated by low pH levels could recolonize after water quality in the damaged lakes improved. Dr. Gray then moved to the state of California to conduct postdoctoral training at the National Center for Ecological Analysis and Synthesis at the University of California, Santa Barbara. His postdoctoral research examined the impacts of climate change on one of the world's largest and most fascinating lakes, Lake Baikal, Siberia. 

Dr. Gray enjoys teaching undergraduate classes and maintains and interest in conducting research on the impacts of environmental change on aquatic ecosystems.
