Tim Evans

Principal Investigator
Tim received his BS in Biology in 2001 from Slippery Rock University of Pennsylvania. He earned his PhD from Indiana University in 2006 studying wing vein patterning in Drosophila with Joe Duffy. He began his studies on axon guidance in the Drosophila embryonic nervous system as a postdoc in Greg Bashaw's lab at the University of Pennsylvania. Tim joined the faculty in the Department of Biological Sciences at the University of Arkansas as an Assistant Professor in 2013.
