Title: Postdoc to develop state-space fisheries stock assessment models at the University of Washington

Position Details

Position Description

Dr. André Punt’s lab at the University of Washington, seeks to hire a Postdoctoral Scholar in the School of Aquatic and Fishery Sciences (SAFS). The position is supported by a Cooperative Institute for Climate, Ocean, and Ecosystem Studies (CICOES) award from NOAA for a project entitled, “Evaluating climate-driven changes in the productivity of Alaska groundfish using state-space stock assessments.” The candidate hired into this position will have the opportunity to be at the forefront of developing climate-informed, state-space stock assessments for Alaska fisheries using cutting edge software.


The Punt lab is dedicated to the development and testing of methods for assessing the past and current status of fish, invertebrate and marine mammal populations. We use these assessments as the basis for forecasts that evaluate which methods for managing these populations will best achieve the goals established by society for those populations. We are exploring how to manage marine populations in the face of changing societal goals, climate change, ocean acidification, and the lack of data which is typical of the marine environment.


The project will involve: 

·        The addition of sex-structure to the Woods Hole Assessment Model (WHAM), a state-space age-structure modeling software package. Sex-structure is a common feature of many important Alaska groundfish assessments, including sablefish and flatfish. WHAM is coded in R and Template Model Builder and is currently used to estimate process error variation and environmental linkages to abundance, recruitment, natural mortality, catchability, and growth.

·        Continued development and application of state-space assessment models to identify climate linkages to variation in recruitment, growth, natural mortality, and catchability of groundfish stocks in Alaska. Proposed case studies include sablefish, Pacific cod, walleye pollock, flatfish species (e.g., yellowfin sole, Alaska plaice), and Pacific Ocean perch.

·        Project deliverables include:

1.     A journal article outlining the motivation and application of state-space assessments to various Alaskan groundfish stocks,

2.     A documented sex-structured version of WHAM,

3.     And travel to scientific meetings to disseminate findings to the broader stock assessment community.

·        The PI and the NOAA collaborators will provide data and support for case studies, and guide code development and statistical implementation.


The salary for this position will be $65,508 per year, or as mandated by a U.S. Department of Labor prevailing wage determination.


Postdoctoral scholars are represented by UAW 4121 and are subject to the collective bargaining agreement, unless agreed exclusion criteria apply. For more information, please visit the University of Washington Labor Relations website.

University of Washington Postdoctoral Scholar appointments are for a temporary, defined period not to exceed five years/60 months, including any previous postdoctoral experience.


Mandatory Qualifications:

Candidates will have confirmed Ph.D. at the time of appointment, in a relevant discipline (e.g., stock assessment, quantitative ecology, statistics).



·        Have experience with R, TMB, population dynamics, stock assessment and model fitting, collaborative coding, and leading scientific publications,

·        Adopt a rigorous and scholarly approach to their science, with evidence of this from presentations and publications,

·        Demonstrate informed curiosity, with the ability to generate novel scientific questions,

·        Be internally, intrinsically motivated to answer the project’s overarching research questions,

·        Be a reliable team member who collaborators can always count on to come through on their promises,

·        Be a respectful, professional, and generous team player who goes the extra mile to help their colleagues and maintains strong collegial bonds,

·        Be an effective mentor for junior colleagues,

·        Have a positive attitude in the face of obstacles or setbacks; have the professionalism to take these inevitabilities in stride,

·        Have excellent time management skills; accomplish research goals by creating realistic but ambitious plans and initiating open communication when plans need to be adjusted,

·        Have the willingness and the courage to discuss issues openly (i.e., to give and receive feedback, to celebrate successes, and to discuss ways to overcome challenges).


Applications will be reviewed on a rolling basis, but those received by July 31, 2023, will be considered as a priority in the first screening. The position will start as soon as possible, but the anticipated start date is September 1, 2023, and no later than May 31, 2024. An earlier start date may be required for candidates who will need more time for training.  The initial appointment will be 100% FTE for one year, with potential renewal for a second year.


Application Instructions:

All applications should be submitted through Interfolio. To apply for this position, please include the following in your application:

·        A letter of intent explaining why you are a good candidate for this position.

·        A current CV

·        PDFs or DOIs of any written materials that demonstrate your previous research experience and your rigorous and scholarly approach to science.

·        Contact information for at least three references in order of importance.
