Joseph Miller, MSc.

Joe is a fisheries scientist with a diverse background in aquatic biology, regulatory compliance and program management in the Pacific Northwest spanning 18 years.  He has worked successfully with federal, state, tribal, and private entities to develop creative, efficient solutions to address complex resource management issues, particularly at hydroelectric projects in the Columbia River Basin.  Much of his professional and academic career has been focused on salmon ecology, evolution and conservation and has included projects along the Westcoast of North America from Southwest Alaska to the Sacramento-San Joaquin Delta.  Prior to founding Four Peaks, Joe played a key role growing a fisheries program at a private consulting firm and he led large-scale fisheries programs at Chelan County Public Utility District and the Washington Department of Fish and Wildlife.  Through these experiences, Joe has gained a reputation for excellent client service and solving complex problems.  As CEO at Four Peaks Environmental, he is surrounded by a team of scientists and engineers that are passionate about their work and share the same commitment to bring our clients superior service and outstanding technical solutions.

Joe holds B.S. and M.S. degrees in Fisheries from the University of Washington, where he studied salmon populations in Alaska. Joe and his family live in Wenatchee, where he can be found running or skiing the trails with his daughters.

Pradeep Mugunthan, PhD., PE

Pradeep has 17 years of experience in hydrodynamic, sediment transport, and water quality modeling and evaluations. As a founding member of Four Peaks, Pradeep is committed to bringing the state-of-the-science in surface and groundwater modeling and environmental data gathering and analysis to develop strategic and efficient solutions tailored to meet the needs of our clients. Pradeep supports clients on water resources and water quality management, especially as it relates to compliance with the Clean Water Act, Endangered Species Act, and Federal Power Act. He has also supported large contaminated sediments and upland sites remediation under the Comprehensive Environmental Response, Compensation, and Liability Act (Superfund).

Pradeep earned his Ph.D. and M.S. degrees in Civil and Environmental Engineering from Cornell University and Carnegie Mellon University, respectively, and a B.S. in Mining Engineering from Anna University. Pradeep lives with his wife and daughter in Chicago, and enjoys hiking, running and traveling.

Joshua Murauskas, MSc.

Josh is an aquatic resources scientist with 20 years of experience throughout North America, working for county, state, federal, and private entities. Josh started his fisheries career working with a conservation district in the 1990s, and has continuously chased opportunities to work in streams, rivers, and lakes throughout the country. His expertise is rooted in migratory fishes – including salmon, lampreys, temperate basses and shads – and applying analytical approaches to large databases to quantify fish behavior, population dynamics, and harvest statistics in modified systems. He has focused on passage and water quality evaluations at Columbia River hydroelectric projects since 2007 (11 years). As a founding member of Four Peaks Environmental, we rely on Josh’s talent and energy on a variety of projects.

Josh earned a M.S. degree in Biology from East Carolina University and a B.S. degree in Biology from Northern Michigan University. He studied analytical programming at SAS Institute in Cary, North Carolina, and is a member of the American Fisheries Society and the American Institute of Fishery Research Biologists. Josh lives in Wenatchee and is usually found on nearby lakes and rivers each weekend with his wife and children.

Mark Weiland, MSc.

Mark Weiland is a scientist with 23 years of experience working in streams, lakes, and rivers throughout North America, and 21 years working in the Federal Columbia River Power System. His technical expertise includes development of new monitoring technologies, leading multidisciplinary research teams, and conducting evaluations in aquatic environments using state-of-the-art technologies – especially in the hydroelectric industry. As a founding member of Four Peaks Environmental, we rely on Mark as a regional expert in active and passive acoustics, acoustic telemetry, and acoustic and optical cameras in modified systems. Mark was integral to the development of several technologies, ranging from the Juvenile Salmonid Acoustic Telemetry System (JSATS) to a Low-Cost Sonar System, in development.

Mark obtained his Master’s Degree in Fisheries Science and Management at the University of Missouri-Columbia and holds a Bachelor of Science in Biology from the University of Wisconsin-Oshkosh. He lives with his wife and children in the Columbia River Gorge near Portland, balancing the excitement of youth sports, outdoor recreation, and keeping elk from harvesting their garden. Mark is recognized as a leader in his community, volunteering as a rescue diver for Skamania County Sheriff’s Office for almost two decades.

Megan Stachura, MSc.

Megan Stachura is a fisheries scientist with 10 years of experience managing, statistically analyzing, and visualizing environmental data and communicating findings for effective natural resource management. Megan previously worked with the National Marine Fisheries Service (NMFS) on a variety of projects, ranging from development of a bio-economic model of recreational fisheries to better understand management tradeoffs, to translating complex science and management information into informative, easy-to-understand profiles of seafood species. Her experience with NMFS has translated well to support our data-rich fisheries projects in the Northwest, often focused on reintroduction of salmon and steelhead populations in highly-modified systems.

Megan earned a M.S. degree in Aquatic and Fishery Sciences from the University of Washington and a B.S. degree in Marine Science and Biology from the University of Miami. She lives in Seattle and is often found in the outdoors, hiking, kayaking, and putting her photography skills to work, capturing fish, wildlife, and natural landscapes.
