T he field of haptics seeks to understand how we use our sense of touch to interface with the world, and then to augment that sense through the design of technological interfaces. Although not yet as well understood as vision and hearing, a thorough understanding of our sense of touch is vital as people and machines are increasingly brought together in daily interactions. Associate Professor Gregory Gerling works on highly collaborative and interdisciplinary projects that bridge computational neuroscience, engineering, medicine and psychology. This interdisciplinary approach is a major theme for research at the U.Va. School of Engineering and Applied Science. His two complementary research directions are: 1) the computational analysis and modeling of how populations of touch-sensitive neurons, which are embedded in the skin, encode an object’s features into neuronal signals, which are decoded by the brain, and 2) the design and analysis of medical simulators to ensure that health practitioners’ hands-on skills are systematically trained, time-effective and highly accurate. Among other projects, he also works in designing graphical user interfaces. We seek to understand the generation of neural action potentials from populations of hundreds of mechanosensitive afferents and their end organs, including the Merkel cell – neurite complex, embedded in layers of fingerpad skin. Our approach is to join computational models with experimental approaches to address questions not approachable by traditional studies. U.Va. ENGINEERING 7
