Professional Experience
My major research area of interest is plant development biology, where I investigate the morphogenesis of leaves.  My students and I conduct descriptive studies of developing leaves using scanning electron and light microscopy, we analyze the genetic regulation of leaf development by investigating mutations in genes that affect leaf form, we conduct manipulative studies on developing leaves in tissue culture using hormones and hormone transport inhibitors, and we characterize the expression of genes believed to be involved in leaf formation by using molecular techniques.  More recently, we have been investigating the response of plants, mosses in particular, to pathogen challenge.  We are interested in how mosses initiate defense mechanisms
