I also do research on, and have written articles and books on the plants of Texas and work in collaboration with colleagues at the Botanical Research Institute of Texas in Fort Worth.
My third area of research is on evolution in extreme environments including tropical rainforests, high mountain peaks, deserts, Antarctica, and the Arctic. In my research I have traveled to all seven continents and have taken students on JanTerm classes and research trips to fifteen different countries.
