Our group studies a diverse set of species and ecosystems because we are interested in mechanisms of evolution and the overarching patterns of diversification that extend beyond any individual place or species. We generally work with whole genome or transcriptomic data and use statistical models to test what factors may have shaped genomic patterns. We mix dry (computational) and fieldwork.

Empirical Earth-life systems:
  1. Top-down geologic controls on genetic diversification of coastal species based on continental shelf width, tectonics, and sedimentation (global)

  2. Dual effects of river formation and monsoon precipitation on speciation of desert tortoises in the southwestern US

  3. Effects of landscape and climatic evolution on adaptation and diversification of plants and animals on the Baja California peninsula, Mexico

Theory of Earth-life evolution:
  1. Formalizing & quantifying the cause-effect relationship between Earth processes and genetic patterns

  2. Quantifying landscape change in a generalizable way

  3. Using information signatures in genomic data to compare speciation across taxonomic groups
