behavior, and 

sexual selection



-An R35-MIRA award from the National Institute of General Medical Sciences will fund the lab from 2021-25. The $1.25million grant is titled: "Mining natural infection variation to find the genetic basis of coevolution between vertebrate hosts and helminth parasites"

-Check out our newest preprint on the evolution of immunity to tapeworms: Evolution of a costly immunity to cestode parasites is a pyrrhic victory


Research philosophy

We use an integrative approach, drawing from practically every biological discipline, to describe the process of adaptation via natural selection. We not only love the organisms and traits that we study, but also believe that broadly focused research is critically important during this period of increasing specialization in science. In addition to adding to the foundation of basic evolutionary science, by studying adaptations that have survived the gauntlet of natural selection, we are poised to mine a largely untapped reservoir of solutions to pressing medical and conservation challenges.

Big questions 

What genetic changes drive variation in ecologically relevant
(i.e. adaptive or functional) traits?
How are host-parasite interactions influenced by coevolution
within and among populations?
How do variable selection and developmental plasticity 
influence the molecular architecture of adaptive traits?
Can we predict and follow natural selection in action?

Fun videos

A great animation by Harvard University undergraduate student Arian Kam. Inspired by my PhD dissertation on the genetics of burrwing behavior in deer mice. Weber et al 2013

A beautiful video, produced by the Howard Hughes Medical Institute, that describes the Bolnick Lab's field

research on Vancouver Island. I collaborate with Dan Bolnick on numerous threespine stickleback projects, and also use Vancouver Island lakes, streams and estuaries as field sites.
