Florida Spectrum Environmental Services (2006 to present)

Microbiology supervisor and senior scientist at FSES after merger of Spectrum Laboratories, Inc and Florida Environmental Services in January, 2006. Currently one of the largest environmental laboratories in Florida.

Spectrum Laboratories, Inc. Experience (1973 to present)

Dr. McCorquodale founded Spectrum Laboratories, Inc. in 1973 and has developed a broad-based analytical laboratory to handle a variety of analytical and consulting problems. With a history spanning over there decades, Spectrum Laboratories has participated in an array of environmental testing projects that have touched virtually every facet of the environmental industry. He served as president and microbiologist with combined management and technical duties. He is also consultant to various drainage districts and the Life Science program of the National Aeronautics and Space Administration.

Other Experience:

Prior to founding Spectrum Laboratories, Inc., Dr. McCorquodale was a staff member in the Department of Biological Science at Florida Atlantic University, Boca Raton, Florida. He was the project microbiologist for U.S. EPA research grant entitled "Biological Control of Aquatic Vegetation.". During his graduate work he functioned as principal investigator of microbiology and blood chemistry under a fellowship for the Equine Research Foundation. At Quincore Laboratories in Deerfield Beach, Florida, Dr. McCorquodale was microbiologist and microbiology section chief, supervising and performing microbiological testing of germicidal products. He is an affiliated faculty member at Nova Southeastern University Oceanographic Center and teaches courses in marine and coastal pollution. He has taught courses in membrane filter techniques for the Florida Water and Pollution Control Operators Association. Dr. McCorquodale serves on the Technical Advisory Group of the Florida Harmful Algal Bloom Task Force and is also a member of the Mayor of Ft. Lauderdale, Florida's Blue Ribbon Committee on Water Quality. Dr. McCorquodale is currently developing methods for indicators of fecal pollution in marine water including coliphage and toxicity testing. When not in the laboratory he enjoys outdoor activities such as sailing, fishing and working in his garden at home. His wife and he love to travel and learn about other cultures and people.
