My interest is the limnology of the Great Lakes.  While my expertise is very limited, i.e,  primary productivity, phytoplankton dynamics, etc.,  I am interested in almost anything to do with the Laurentian Great Lakes.  Moreover, I find it a privilege to have spent my entire life enjoying and studying the Great Lakes.

Research Interests

  • Limnology of the Great Lakes
  • Primary productivity
  • Phytoplankton dunamics
  • Laurentian Great Lakes
