Biomechanics is the application of mechanical principles to biological systems, such as humans, animals, plants, organs and cells. Biomechanics is closely related to engineering, because it often uses traditional engineering sciences to analyse biological systems. Some simple applications of Newtonian mechanics and/or materials sciences can supply correct approximations to the mechanics of many biological systems. Applied mechanics, most notably mechanical engineering disciplines such as continuum mechanics, mechanism analysis, structural analysis, kinematics and dynamics play prominent roles in the study of biomechanics.

Dr. Chang is the director of the Comparative Neuromechanics Laboratory in the School of Applied Physiology. His research program focuses on trying to understand how animals move through and interact with their environment. He integrates approaches and techniques from both biomechanics and neurophysiology to elucidate both passive mechanical and active neural mechanisms that control limbed locomotion in humans and other terrestrial vertebrates. This multidisciplinary approach allows him to test hypotheses about the basic design and function of the locomotor apparatus throughout a variety of conditions. His current goal is to understand the extent to which muscular reflexes can influence limb coordination during locomotion and how global limb control strategies may be affected by sensorimotor perturbations.

A few common scientific themes emerge frequently in our projects: biophysics at interfaces, the use of quantitative modeling, collective interactions of cells and/or molecules, cell mechanics, cell motility and adhesion, and in many cases, the role of bulky sugars in facilitating cell integration and rearrangements in tissues.

Dr. Hammond’s research focuses on the design and control of adaptive robotic manipulation (ARM) systems. This class of devices exemplified by kinematic structures, actuation topologies, and sensing and control strategies that make them particularly well-suited to operating in unstructured, dynamically varying environments - specifically those involving cooperative interactions with humans. The ARM device design process uses an amalgamation of bioinspiration, computational modeling and optimization, and advanced rapid prototyping techniques to generate manipulation solutions which are functionally robust and versatile, but which may take completely non-biomorphic (xenomorphic) forms. This design process removes human intuition from the design loop and, instead, leverages computational methods to map salient characteristics of biological manipulation and perception onto a vast robotics design space. Areas of interest for ARM research include kinematically redundant industrial manipulation, wearable robotic devices for human augmentation, haptic-enabled teleoperative robotic microsurgery, and autonomous soft robotic platforms.

Subsequently, we are interested in combining these 3D printed biomaterial platforms with biologics for patient specific regenerative medicine solutions to tissue reconstruction.
