Our Experienced and Capable Staff
Sharon K. Taylor, DVM, PhD, Group Manager, sktaylor@usbr.gov, 303-445-2052
The Fisheries and Wildlife Resources Group has a highly experienced senior scientific staff with over 250 combined years of research and Reclamation experience. We are proven specialists with extensive experience in all disciplines needed for environmental sciences and regulatory studies and assessments, along with insider knowledge of Reclamation facilities, history, and issues. Our group benefits from the expertise of two senior fishery researchers from the USGS who work with us frequently under cooperative agreement. We also have a skilled pool of contract specialists and technicians that can be quickly augmented to meet mission requirements and time deadlines.
