I am broadly interested in how changes in developmental dynamics facilitate morphological evolution. I began this interest by studying lamprey retinal development during my undergraduate work at the University of Southern Indiana. Following this, I studied how gene expression patterns have changed to produce divergent morphologies in the mite Archegozetes, including its reduction of segmentation, limb development and the deployment of Hox genes, for my PhD work at the University of Southern Illinois. After graduating, I studied the genetic input of Rho kinase substrates on establishing planar cell polarity in the developing eyes and wings of Drosophila during my postdoc at the Albert Einstein College of Medicine in New York. My current interests focus on the genetic input needed to induce germ cell production in the cricket to answer questions surrounding the evolution of germ cell specification.
