Auburn, California

Brad has more than 23 years of experience working on anadromous and estuarine fishery issues in California and has attained expert knowledge of regulated rivers and estuaries, particularly related to the ecology of Chinook Salmon and other anadromous fishes. Brad excels in high-level data analysis including life-cycle modeling and simulation modeling of management impacts and the development, application, and evaluation of quantitative models for assessing aquatic habitats and fish population dynamics. Brad previously served as an environmental scientist with the California Department of Water Resources and was the lead scientist for hydropower re-licensing.
