Lucius Caldwell, Ph.D., Senior Fisheries Scientist Dr. Lucius Caldwell draws from a broad background to find creative solutions to client challenges. Dr. Caldwell has experience coordinating project logistics, undertaking field-based research monitoring and evaluation (RM&E) projects, developing and employing molecular tools for organismal inquiry, and utilizing cutting edge techniques to help solve emergent ecological problems.

Background: Dr. Caldwell received his PhD in Biological Sciences from University of Idaho in 2014, where he studied endocrine mechanisms that underlie O. mykiss rematuration in steelhead kelts. During this time, he collaborated with the Nez Perce and Yakama tribal fisheries programs, CRITFC, and various federal agencies. He also holds an MS from University of Maine (2009) and a BSc from McGill University (2005). He has been involved in fisheries work since 2006, when he got his start working as a USFS stream technician in Central Idaho. Most recently, he worked as a Fisheries Biologist for the Yakama Nation, coordinating field operations and data analysis with a small crew based in the Methow Valley (WA) that researched the effects of various restoration actions including habitat restoration and nutrient augmentation. Areas of particular interest to Dr. Caldwell are 1) coordinating collaborative implementation and RM&E efforts, and 2) using molecular approaches to generate organismal inferences that help answer ecological questions and solve environmental problems. He has experience with techniques and tools for investigating environmental endocrine disruption and ecotoxicology, in addition to more classic fisheries resource management issues. Dr. Caldwell holds various certifications, including boater safety, safe electrofishing practices, and wilderness first responder.

Personal: When not at work, Lucius spends as much time outdoors as possible. He enjoys colluding with his wife to making their son chuckle, exploring the region with his family, racing xc mountain bikes, skiing, throwing dry flies on tenkara rods, and pretending he knows how to play various stringed instruments.
