I am broadly interested in examining animal form & function using the lenses of comparative anatomy, muscle physiology, and biomechanics. My research centers around two comparative themes: 1) exploring the diversity of vertebrate musculoskeletal systems; and 2) linking physiological properties of muscles to whole-organism performance. Both themes are ideally suited to collaborative studies with student researchers because they involve tangible interactions ("How wide must a predator open its mouth to eat a given prey?") and intrinsically relate to how one's own body moves and functions. I've spent the majority of my career studying fishes (though I'm an equal opportunity zoologist), and I'm particularly interested in how organisms obtain and process their food. Methods and tools employed in the Gidmark lab include CT scanning, 3D printing, Animal surgery, 3D biomechanical modelling, electromyography (muscle activity), High-speed videography (light and x-ray), Muscle stimulation & force measurement, Xray Reconstruction Of Moving Morphology (www.XROMM.org), and Clearing & staining -- come by my office (SMC B220) or lab (SMC B010) and take a look!
