Overview
We conduct research on broad issues in
evolutionary genetics, and we
are currently addressing questions relating to
the evolution of adaptation, reproductive isolation,
breeding systems, inbreeding depression, and
floral traits in natural plant populations.

The genetic basis of traits associated with the evolution of serpentine endemism in monkeyflowers.
Journal Article Evolution; international journal of organic evolution · January 2024 The floras on chemically and physically challenging soils, such as gypsum, shale, and serpentine, are characterized by narrowly endemic species. The evolution of edaphic endemics may be facilitated or constrained by genetic correlations among traits contri ... Full text CiteBeyond Content, Understanding What Makes Test Questions Most Challenging
Journal Article BioScience · March 1, 2023 When students answer test questions incorrectly, we often assume they don’t understand the content; instead, they may struggle with certain cognitive skills or with how questions are asked. Our goal was to look beyond content to understand what makes asses ... Full text CiteThe genetic architecture and evolution of life-history divergence among perennials in the Mimulus guttatus species complex.
Journal Article Proceedings. Biological sciences · April 2021 Ecological divergence is a fundamental source of phenotypic diversity between closely related species, yet the genetic architecture of most ecologically relevant traits is poorly understood. Differences in elevation can impose substantial divergent selecti ... Full text CiteRecent Grants
