I worked on salmon for my graduate studies at the University of Washington, and also as a postdoc at the University of Massachusetts Amherst. I have continued to collaborate on salmon projects because, well, salmon are cool.

Adjacent is the book effort that facilitated my transition from research focuesd on salmon to research focused on evolutionary biology focus. Here is the blurb I wrote for the book jacket:

Salmon made their entrée into evolutionary biology in no less than the first major treatise on the subject: Charles Darwin’s “On the origin of species”. This was followed by cameos in Darwin’s “Descent of man and selection in relation to sex.” Since those early days, the links between salmon biology and evolutionary theory have waxed and waned, with the past decade seeing an emergence of new ties between the two fields. This book seeks to illustrate and advance those ties, providing novel insights into what salmonids (salmon, trout, charr, whitefish) can tell us about evolution and what evolution can tell us about salmonids. Most of the chapters use salmonids as a model system for examining specific aspects of evolutionary theory: life histories, philopatry and dispersal, migration, egg size and number, reaction norms, ecological speciation, evolutionary rates, hybridization, breeding systems, and population genetics. The final few chapters highlight the contributions that evolutionary theory can make to the conservation and management of salmonids. By addressing this last issue, we hope to encourage further integration of evolutionary theory and conservation biology, and more generally, basic and applied research.

5. Natural selection acting on stream-dwelling Atlantic salmon in a restoration program
Efforts to restore populations to locations from which they have been extirpated may be hampered by mal-adapation in the introduced group (because they came from a different environment). Estimates of natural selection acing on the new population can be used to deduce mal-adapation and tailor efforts to reduce its effects. We estimated natural selection acting on Atlantic salmon (Salmo salar) undergoing restoration to the Connecticut River, U.S.A. PDF
