Jerrold Davis

My principal area of interest is systematic biology, and within this area, my research is focused on systematics of the grass family (Poaceae) and other monocots. I am engaged in studies of phylogenetic relationships within the grass family (Poaceae) and across monocots as a whole, using molecular, genomic, and morphological character sets. I also work on species-level problems, including the development of appropriate methods for inferring species boundaries on the basis of population variation patterns. I have employed these methods in my studies of species boundaries in the grass genus Puccinellia, and these analyses have contributed to my floristic studies of this genus.
