Professional Licenses:

  • Professional Engineer, New York State (#067275)
  • Private Pilot (FAA)


  • BS, MS, PhD, 1974, Environmental Engineering (Limnology), Rensselaer Polytechnic Institute, Troy, NY.


My Master’s Thesis was on the paleoecological use of diatoms as environmental indicators in Lake George. My Doctoral Dissertation subject was a Simulation Model of Microbial Ecology and was also related to work done at Lake George. During the late 1970s, I edited the series of books for Academic Press, The Lakes of New York State. From 1980 to 1983, I was stationed in Lake George Village and directed the Lake George site for the National Urban Runoff Program (NURP).

During my later tenure at DEC, I served as the Chief of the Inland Lakes and Freshwaters Section. I was the supervisor of seven scientists, three professional engineers, other professionals and support staff conducting studies concerning all aspects of lake management and aquatic ecology.

My areas of effort included water quality monitoring, TMDLs, water quality standard development, simulation modeling, nuisance aquatic plant control, dredging and other lake restoration techniques, acid precipitation surveys, toxic substances, hazardous waste remediation, comprehensive land use and water quality plan development and implementation of the New York State Clean Water/Clean Air Bond Act and Environmental Protection Fund. I also prepared testimony and affidavits for litigation.

I have extensive experience working with local government officials, preparing and managing large, comprehensive grants and projects.
