Saltwater Inc. is seeking a postdoctoral scientist to develop diagnostic tools for evaluating state-space stock assessment models. Although state-space assessment models have become increasingly popular in recent years, there are open questions regarding whether traditionally-used stock assessment model diagnostics (such as retrospective error, model residuals, etc.) are reliable indicators of model performance in state-space models. The research project will use an established operating model to generate simulated stock assessment datasets and test a variety of commonly-used and newly-developed diagnostic metrics. The goal will be to determine which diagnostics perform best at identifying the model with the lowest estimation error. The postdoctoral scientist will have the opportunity to develop their own diagnostic tests and apply the methods to real datasets, which will inform the 2023 State-space Assessment Methods Research Track


Minimum qualifications include a Ph.D. in quantitative fisheries, statistics, applied mathematics, marine fisheries ecology, theoretical ecology, or a related field. Strong quantitative skills are required. Experience in quantitative modeling, stock assessment, population dynamics, statistics, and computer programming (R, Template Model Builder, AD Model Builder) are preferred. The successful candidate will be motivated and capable of working independently and collaboratively. The successful candidate will be expected to give oral presentations at a range of scientific fora, as well as publish in peer-reviewed written literature.
