Jonathan Richmond's research focuses on ecological speciation in North American scincid lizards of the Plestiodon skiltonianus species complex. Specifically, he is interested in understanding how divergent natural selection has influenced the evolution of reproductive incompatibility among clades that differ in their ecology. Although most classic theories of speciation incorporate a role for natural selection in species formation, remarkably few cases of ecological speciation have been demonstrated in natural systems, and the importance and prevalence of natural selection in the speciation process remains an open ended question.

The aquatic and wetland plant family Menyanthaceae comprises five genera, with species distributed worldwide. Many species in the family, particularly in the genus Nymphoides, are traded in the ornamental aquatic plant trade and consequently have become naturalized outside of their native ranges, with some even considered nuisance weed plants. The research of Nicholas Tippery focuses on the evolutionary relationships between genera and species of Menyanthaceae, with respect to both their vegetative and reproductive morphology.
