I’m Jeremy Yoder, an Assistant Professor in the Department of Biology at California State University Northridge. I study local adaptation and coevolution — the ways that living things shape each other’s evolutionary history — particularly in mutualism.

Evolutionary theory explains how events that occur over a single day or a single growing season ultimately shape million-year-long patterns of biodiversity. I use field studies, mathematical models, and genomic data to understand how interacting species shape each other’s evolutionary history. 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.
