John Bratton
John F. Bratton, Ph.D., is a senior scientist at LimnoTech with broad expertise in earth and environmental science, including successful leadership of projects involving large ecosystem monitoring and restoration with a nutrient reduction focus, remedial investigations for contaminated sites, and litigation support. He has worked as a consultant, researcher, educator, and science manager for over 30 years, especially in the Northeast, Great Lakes and Pacific regions, and has contributed to over 150 widely-cited scientific publications and research presentations. His publications cover groundwater-surface water interaction and contami-nant transformations, coastal and glacial geology, freshwater and ocean sediment biogeochemistry, environmental history on decade to century scales, and environmental law and policy.
