Research InterestsMy research focus is computer graphics, although my interests extend to related fields such as computer vision and robotics. My dissertation research investigated using motion capture data to build generative models of visually realistic human motion. These models allow a user to create sophisticated animations simply by providing high-level requirements for a character, e.g., ``walk up to this box and lift it''. The primary contribution of my thesis is the development of automated methods for building data-driven motion models from large data sets. This is important because the range of motion that can be produced from a data-driven model is limited by the amount of input data, and so flexible models require both large data sets and automated tools that make working with these data sets feasible. Specific results of my thesis work include:
