TRRP Staff

Get to know us!

TRRP has a central office in Weaverville, but also includes people working in a number of offices in other communities around Northern California. It takes contributions from many individuals to guide TRRP management actions. While reaching agreement on research needs and restoration activities with many individuals involved in the process can be difficult and takes time, it removes individual priorities and optimizes our work for the river. There are ways you can get involved too!

This list includes all staff of the Weaverville office, all others who are current members of TRRP Workgroups, and a few more who work on program activities. Biographies, photos, and contact information are included only for staff who have submitted this information for public viewing. Those working in the main TRRP office in Weaverville have their names in blue.

Bill has been studying fish and their habitats in the Humboldt Bay area since 1993. His early career pursuits included marine fish ecology and the importance of marine zooplankton to fish populations. Bill graduated from Humboldt State University in 1995, and moved to Seattle to work on his Master's degree at the University of Washington (UW) School of Fisheries. At UW Bill worked with the Joint Institute for the Study of Atmosphere and Ocean / Pacific Northwest Climate Impacts Group to understand climatic forcing mechanisms of the nearshore marine environment  and the resulting impacts to marine survival of coho salmon to improve Washington Department of Fish and Wildlife's coho salmon harvest forecast model. Following completion of his Master of Science degree from UW, Bill moved to Newport Oregon to work as a faculty research assistant to research climate forcing mechanisms on early life history of sablefish, looking closely at otoliths to try and find a 'climate signal'. Bill served a brief stint with the National Marine Fisheries Service working with zooplankton before moving back to Eureka to work for the U.S. Fish and Wildlife Service in late 2001. Bill's duties with The Service began with monitoring juvenile fishes, involved work with rotary screw traps and acoustic and radio telemetry, and currently serves as the lead of the Monitoring and Assessment division of the Fish and Aquatic Conservation Program at the Arcata Fish and Wildlife Service. Bill serves on multiple technical advisory committees and is especially proud of his work with the Pacific Marine and Estuarine Partnership. Bill loves to be outdoors with his wife Jenny and puppies Frankie and Beans, and when conditions allow can be found recreating on or in the ocean.

Christine grew up on a large cattle ranch in Gleeson Arizona, chasing cows, pigs and chickens, riding horses, motorcycles, OHVs and shooting guns.  Of course, a girl like that would have attended school in Tombstone Arizona where she got to meet the Harlem Globe Trotters; she played basketball then too.  Christine opened the first video store in Tombstone with a business scholarship while studying business at Cochise College in Sierra Vista, AZ.  
 
Two years later she enrolled in the Watershed Management Program at the University of Arizona in Tucson.  While at the U of A, she worked 3 years as a federal employee with USDA -Agricultural Research Service  (ARS) on the Watershed Erosion Prediction Project (WEPP).  WEPP was designed to replace the Universal Soil Loss Equation and the revised equation (USLE / RUSLE).  She spent her summers on the road traveling the western United States with ARS.  Her job was to conduct rainfall simulations, determine steady state runoff by watching hydrographs and then coordinate runoff sampling to determine rainfall/erosion and sedimentation rates at different rainfall intensities.  She synthesized all the data for the rangeland portion of the simulations.  
 
Two weeks after graduating from the U of A she received a permanent full-time position as a hydrologist on the Eldorado National Forest in Placerville, CA where she remained for 17 years before transferring to the Shasta-Trinity NF where she is presently.  She enjoys participating on Burn Area Emergency Rehabilitation (BAER) teams and has taught many classes and mentored hydrologists about methods and models to predict increases in peak flows and erosion following wildfire. She served on the Sierra Nevada Framework and Monitoring Team that developed Standards and Guidelines for the Forests in the Sierra Nevada Mountain Range and helped to develop a Forest Plan Amendment for Rangelands on the Eldorado & Tahoe National Forests.  Her area of expertise is cumulative watershed effects analyses.  
 
She is the proud parent of two college students Keenan at Dominican University in San Rafael CA, and Karly Mai attending CSU-Monterrey Bay in Seaside, A.  She is especially looking forward to watching their careers & families develop in the future.

Restoration Ecologist

Yurok Tribal Fisheries Program

Photo of Emily J. Cooper-Hertel

I am passionate about the recovery and conservation of wild salmon and trout through fostering river ecosystem self-renewal. I have experience since 2012 in multiple facets of applied natural resource science where I’ve specialized in fisheries biology, stream geomorphology, ecohydrology, watershed revegetation restoration, research science, project management, and logistics coordination. I earned my B.A. in Environmental Studies from Hendrix College (2010) in my home-state, Arkansas, and my M.S. in Natural Resource Science from Humboldt State University (2017) in Arcata. Specifically, much of my professional experience is focused on coastal watershed, instream, and wetland restoration, fish habitat assessment and capacity modeling, juvenile salmonid growth and survival, using hydraulic-flow relationships for ecological risk assessments in streams, and broader linkages between river geomorphology, hydrology, and biology. I utilize ground-based and geospatial scientific methods for explaining natural processes and interactions. Much of my work has taken place throughout the Eel River and Klamath-Trinity River watersheds, aiming to inform water resource and fisheries management. My involvement with the TRRP through the Yurok Tribe has mostly consisted of Trinity River juvenile habitat assessment, juvenile growth assessment in thermally diverse habitats, and participating in the Flow Workgroup. In my free time, I love backpacking, camping, surfing, ocean and trout fishing, river rafting, river snorkeling, bike trips, traveling, and finding myself in the next adventure with my husband and two dogs. I also spend a lot of time gardening! I love growing food and flowers, and making bouquets for my community in Bayside. I’m constantly in awe and inspired by the beautiful northern California area I get to call home.

Photo of Karl Seitz

I was born and raised on Long Island, just outside of New York City, and have always been interested in ecological sciences, particularly marine biology and fisheries. I would say my fisheries career began in 2005, while I was in high school, when I attended a summer program at the Acadia Institute of Oceanography in Maine learning basic field techniques in marine science. The next summer, I worked on my first true research project at Stony Brook University’s Marine Science Research Center investigating the environmental origins of the Quahog clam parasite QPX via eDNA processing. I then attended the University at Buffalo, graduating in 2012 with a BS in Biological Sciences with a concentration in Ecology and Evolution and a minor in Geology. Soon after graduating, I found myself in the remote wilderness of Kodiak Island, AK working for the Kodiak Regional Aquaculture Association (KRAA) monitoring Pacific Salmon populations and working at their hatchery facilities. This was the beginning of my salmon-centric career path. I spent the next 2 years bouncing around Washington, Oregon, and Alaska working various salmon related field and hatchery positions, gaining valuable experience and insights into the research and management of Pacific Salmon. During this period, I decided I needed to augment my growing field skills with additional academic coursework focused specifically on fisheries. So, in 2014, I enrolled at the School of Aquatic and Fishery Sciences (SAFS) at the University of Washington and in just over a year earned another BS degree. While at SAFS, I worked with scientists at NOAA’s Northwest Fisheries Science Center on a post-dam removal anadromous salmon recolonization project for my capstone research and volunteered on a University of British Columbia led research project investigating the effects of stream habitat structure on juvenile salmonid growth rates and condition factors. I also worked part-time at Wild Salmon Seafood Market in Seattle, gaining insight into the commercial side of the fisheries industry. After another summer season in Alaska running remote monitoring camps and performing hatchery duties for KRAA, I joined Dr. Jonathan Moore’s Salmon Watersheds Lab at Simon Fraser University (SFU). My MSc thesis work was focused on estuary community ecology, specifically the identification of nursery habitats and the effects of saltwater intrusion on fish community assemblages in the Koeye River estuary on the Central Coast of British Columbia. While working on my thesis, I also managed field operations for the Koeye River Salmon Ecosystems Research Project, a collaborative initiative between SFU, the Heiltsuk Nation, and the Hakai Institute, and after I defended my thesis in early 2020, I was hired on as the Project Manager. I stayed with the Koeye Project until July 2021 when I was brought on by the Hoopa Valley Tribe (HVT) into my current position as the Fisheries Management Division Lead. Here in Northern California, I look forward to working with HVT to strengthen their fisheries, revive dwindling salmon stocks, improve hatchery practices, and restore degraded habitats.

As a fourth generation Humboldt County native, Ken is proud to focus his career and expertise on restoring local ecosystems. After receiving his bachelor’s degree in human evolution and evolutionary psychology from U. C. Santa Barbara, he hiked, backpacked, and rock climbed his way through the natural wonders of California and New Zealand before discovering the natural resources field. His career in the field began as a hydrology and water quality technician for the Yurok Tribe on the lower Klamath River through the AmeriCorps Watershed Stewards Program, followed by a second year as a fisheries technician for CDFW trapping, tagging, counting, and otherwise enamored by salmon and steelhead in small coastal streams of Humboldt County. After several years as a field technician he returned to school and obtained an M.S. in Fisheries from Humboldt State University in 2014. He spent the next two years working as a quantitative ecologist in the consulting industry largely focused on experimental design and analysis of wildlife populations associated with the alternative energy sector. In 2017 he returned to CDFW to assume a coordinator role with TRRP, where he serves on several technical work groups and provides field and analytical support for various science projects. In his free time, you might find Ken standup paddle boarding or rafting the Trinity River, exploring nature across the West with his wife, or designing and building furniture.

I have spent a great deal of time exploring the north coast as a student, outdoor enthusiast, and employee of multiple agencies and private consultants. After graduating from HSU for the second time, I gained employment with the USFS in northeastern Washington as a District Fisheries Biologist but longed for a return to the challenge of addressing the multitude of issues facing anadromous fisheries. To that end, I accepted an opportunity in 2016 to join NMFS’ famed Interior Columbia Basin Office in Ellensburg, Washington. Under the guidance of my experienced NMFS cohorts I made the transition from field crew lead to Section 7 consulting biologist. My time in the Columbia Basin was a grand adventure as I explored the intricacies of the ESA as well as the basin itself from British Columbia to Hood River. Although I grew up in the Sierra foothills I was always drawn to the tremendous rivers and fisheries of California’s north coast and leapt at the chance to return there with an opening in NMFS North Coast Branch in 2019. With extensive cooperation and guidance from multiple TRRP and NMFS personnel, I was the primary author of the Biological Opinion for the TRRP’s Mechanical Channel Rehabilitation, Sediment Management, Watershed Restoration, and Monitoring Actions. I look forward to engaging with the TRRP and partners in implementing the program for years to come. I enjoy fishing, mountain biking, whitewater boating, and spending time with family.

Seth was born in Oregon, but grew up in Pittsburgh, PA (Go Steelers!). Seth grew up fishing in every stream, ditch, river, pond or lake he possibly could. Among other proud achievements, at the age of ten he used fishing line with a hook and a worm tied to a remote-control car to pull trout out of a pond. He became an avid kayaker and rafter soon after high school, eventually spending time running rivers throughout the western US. He earned a B.S. in Fisheries and Wildlife Biology from Oregon State University in 2001. Upon moving to Humboldt County, Seth worked for the Yurok Tribe for about five years, performing data collection and studies on the Klamath and Trinity rivers. During that time, he earned an M.S. in Fisheries Biology in 2008 from Humboldt State University. He began working in his current position for the National Marine Fisheries Service in 2008. Seth participates in several of the TRRP’s work groups, the Trinity River Hatchery Technical team, and is an alternate on the TMC. He is a longtime resident of Humboldt County, where he enjoys hunting and fishing and kayaking.

Tyler grew up in Southern Illinois surrounded by corn fields and muddy rivers, but fell in love with fish, specifically salmonids, on weekend fishing trips with his family in Missouri’s spring fed rivers.  This interest in the outdoors was bolstered by many family vacations racking up miles on National Park road trips. Ty was interested in science and biology, but living in an agricultural region, believed his only career path in the field would be in medicine. Thankfully, during his undergraduate program at McKendree University, Ty’s advisor recommended him to field classes at the University of Michigan Biological Station. Here is where Ty’s passions and a career truly merged. He began spending his summers volunteering and working seasonally for the U.S. Forest Service, first surveying for Bull Trout in Idaho’s Sawtooth National Recreation Area and then assessing barriers for non-native Brown Trout removal in Utah’s Ashley National Forest. This experience led Ty to pursue his Masters in Fish, Wildlife and Conservation Ecology with the USGS Fish and Wildlife Cooperative Research Unit at New Mexico State University. Ty’s thesis explored the effectiveness of management strategies for threatened Gila Trout in a fire prone system experiencing the effects of global climate change. Ty assessed the thermal limits for three lineages of the species and the effectiveness of repatriation stocking of a population extirpated by wildfire. Ty entered the U.S. Fish and Wildlife Service through a Directorate Fellows Program internship collecting baseline habitat data for Rio Grande Sucker and Rio Grande Chub on the Baca National Wildlife Refuge in Colorado. Upon completion of this fellowship and his graduate degree, Ty was hired on permanently as a fish biologist at the Arcata office of the US Fish and Wildlife Service and is now the lead for the office’s Klamath Basin Juvenile Salmon Outmigrant Monitoring team. He is also a part of the USFWS Employee Ambassador Program for the Pacific Southwest and a co-chair of the FWS Pride Employee Resource Group. When not at work, Ty enjoys spending time with his fiancé, Dylan, and their gremlin of a dog, Smudge.

Veronica was born and raised in in the remote Sierra Nevada foothills. Growing up amongst granite in the gorgeously rugged Tahoe region, she’s always been more comfortable in the great outdoors than in concrete jungles. After earning a B.S. in Environmental Chemistry from UC Santa Cruz in 2014, she found herself on the North Coast, where she happily hung up her indoor-dooming lab coat for a career in ecological restoration. She lived and worked on California’s Lost Coast for almost 8 years, where she managed a native plant nursery, oversaw revegetation monitoring and invasive species removal, and gained experience with prescribed fire and public outreach. During this time, she co-authored a book to native plants of the Lost Coast, which is currently awaiting publication. Veronica works for HVT at the TRRP office and is involved with riparian revegetation implementation and design, and collaborates with several interagency workgroups. In her free time, she can be found writing about, photographing, hiking to, gardening with, or studying plants, typically far outside the tendrils of civilized society
