Welcome

I’m Jeremy Yoder, an Assistant Professor in the Department of Biology at California State University Northridge. I study coevolution — the ways that living things help and harm each other, and how those interactions shape the evolutionary history of the species involved.

The fundamental hypothesis of evolutionary ecology is that processes taking place over a single growing season are ultimately responsible for patterns of biodiversity that emerge over millions of years. As an evolutionary ecologist, I use field studies, mathematical models, and population genomic data to understand how the ecological effects of different interacting species, habitats, and climates create and maintain biodiversity. For more detailed project descriptions and opportunities to join in research at the undergraduate, graduate, and postdoctoral level, see my lab website.

My doctoral dissertation research with Olle Pellmyr at the University of Idaho applied theoretical, phylogenetic, and population genetic approaches to examine the origins and evolutionary trajectories of species interactions, with particular focus on the obligate pollination mutualism between Joshua tree (Yucca brevifolia) and yucca moths (Tegeticula spp.). As a postdoctoral researcher with Peter Tiffin at the University of Minnesota I used genome-scale genetic data to examine patterns of local adaptation to climate and mutualistic rhizobial bacteria in the model legume Medicago truncatula, as part of the Medicago Hapmap Project. In a second postdoc with Sally Aitken at the University of British Columbia, I studied the genetic architecture of adaptation to climate by lodgepole pine (Pinus contorta) and interior spruce (Picea glauca, P. engelmannii, and their hybrids) with the AdapTree project.
