Dr. Robert Lemanis
I am a paleontologist whose primary interest is in understanding functional morphology and biomechanics. My research focuses on understand the relationship between form and function in extinct animals and what role these relationships might have had on morphological evolution, primarily in cephalopods. Most of my research relies on computational techniques, such finite element analysis, combined with data from multiscale tissue mechanics.
