Julia Molnar investigates the evolution of vertebrate locomotion. She uses three-dimensional virtual models of fossil and living animals to study how muscle leverage, joint range of motion, and other biomechanical factors change over evolutionary transitions and across different environments. Her main interest is in non-mammalian vertebrates such as lobe-finned fish, early tetrapods, salamanders, lizards, and crocodylians.
Molnar received her Ph.D. in evolutionary biomechanics from the Royal Veterinary College, University of London in 2013; her M.A. in medical and biological illustration from Johns Hopkins University in 2009; and her B.F.A. in fine arts from the Maryland Institute College of Art in 2003.
