I am a multi-disciplinary scientist and engineer, an educator and entrepreneur. I am passionate about building digital human models. I have made major contributions to physics-based animation, biomechanics, multisensory displays (with haptics and sound), robotics, and neural control of movement. I have trained some of the leading researchers in the world in the field of physics-based simulation.I love building novel software and hardware systems, and translating research into useful innovations. I founded the UBC spinoff company Vital Mechanics Research to bring my fundamental research on digital human models to real-world applications.
