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.

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

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

  3. 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.
