NOAA Fisheries conducts stock assessments to provide scientific information for the regional fishery management councils and other management partners. The statistical models and diagnostic tools used to assess fish stocks can differ by region, laboratory, and application; although, many assessment approaches have similar mathematical and statistical attributes. The postdoctoral associate will compare and evaluate four age-structured assessment packages commonly used by NOAA Fisheries: the Age Structured Assessment Program (ASAP), the Assessment Model for Alaska (AMAK), the Beaufort Assessment Model (BAM), and Stock Synthesis (SS). Comparisons will rely on simulated data typical of fish stocks in various regions of the United States.

This project requires strong quantitative and programming skills (e.g., in R, AD Model Builder). Qualified applicants will have a background in population dynamics, stock assessment, theoretical ecology, applied mathematics, or statistics. The associate will work with a team of collaborators from multiple NOAA Fisheries Science Centers and Headquarters (southeast, northeast, northwest, Alaska, and the Office of Science & Technology) and may choose their host laboratory from locations in Miami FL, Beaufort NC, Silver Spring MD, Woods Hole MA, Newport OR, or Seattle WA. The associate will have opportunities to travel to the other locations to collaborate with scientists knowledgeable on each assessment package.
