Emms Lab: Research in Plant Ecology
Currently I am collaborating with Dr. Amy Verhoeven at UST and Dr. Susan Mazer at the University of California Santa Barbara on a five-year, NSF funded project to study the joint evolution of mating systems, life-history strategies, and drought physiology in the Californian genus Clarkia. I am also working on the evolution of reproductive allocation and gamete packaging strategies in prairie larkspurDelphinium virescens in Minnesota.
