Ray Timm, Ph.D., Senior Fisheries Ecologist Dr. Timm is an expert in disturbance and restoration ecology in alluvial rivers. His interests are centered on understanding the linkages between imperiled species recovery and the composition and configuration of their habitats. Explicit geographical analyses provide important insights into critical boundaries, and how the movement of energy and materials across them influences ecological systems. He is particularly interested in trying to understand the scales at which cause and effect dynamics result in ecosystem changes. In a restoration context, understanding the space and time relationships between organisms and the processes and functions of their habitats is key to species recovery and conservation.

Responsibilities: At Cramer Fish Sciences, Ray's focus is on restoring fish habitat function in rivers of the Pacific Northwest. Ray is an empirical scientist that is driven by understanding the nature of river ecosystems and the ways in which their impairments can be removed in order to help focus rare restoration dollars on the places where they can do the most good for fish. He is highly skilled at integrating spatial data with statistical models and biological response data to inform sampling designs and restoration plans that produce favorable outcomes.

Background: Dr. Timm earned his B.Sc. in Biology from Northern Michigan University in 1992. In 1996, he received his M.Sc. in GIS and Remote Sensing from Eastern Michigan University. The focus of his thesis was on the disturbance caused by the incipient Zebra Mussel (Dreisenna polymorpha) invasion of North America. His Ph.D. was from the School of Aquatic and Fishery Sciences at the University of Washington (2013). There he studied the population-scale biological response of sockeye salmon (Oncorhynchus nerka) to a century of river management that substantially dampened fluvial ecosystem function, and the system response to a channel-damming landslide that reconnected the river with its floodplain.

Prior to joining Cramer Fish Sciences, Ray worked in both consulting and government roles. He has spent innumerable hours capturing, measuring, and observing how and when fish select specific habitats. He has authored peer reviewed articles, book chapters, and government reports on the topic. His perspectives on restoration have been profoundly informed by his education, work experiences, and the muddy boots and wet jeans of his childhood that accompanied trying to trick a fish into eating a worm.

Personal: Outside of work, Ray enjoys bike riding and sitting around a campfire with his wife and daughter, and is perennially bothered trying to unlock the riddle of the steelhead and the fly.
