Staff Scientist (July 2011 – present)
Research Associate (2009-2011) 
I am a cell biologist with a broad background in development, genetics, and molecular biology, and a specific focus in microscopy and imaging modalities. My research interests have always focused on the establishment and maintenance of form and function. These include development and differentiation and in particular the ability of a seemingly differentiated cell type to de-differentiate, divide, and re-differentiate. I was born and raised in Chicago and earned my B.S. in Biology from Purdue University. I received my Ph.D. in Molecular Biology from the University of Utah, where I studied muscle adhesion in C. elegans with Mary Beckerle. I first joined the Department of Cell Biology at The Scripps Research Institute in 2004 as a postdoctoral fellow with Velia Fowler where I studied myofibril assembly and heart development during mouse embryogenesis and was a George E. Hewitt Foundation for Medical Research Fellow. I began working with Holly Cline in 2009 as a postdoctoral fellow and was appointed to a Staff Scientist position in 2011. My current research in the Cline Lab is to identify the molecular mechanisms involved in recovery from brain injury in Xenopus laevis.
