Research
I'm currently interested in the reconstruction and animation of digital humans and other virtual characters, especially involving the use of novel AI techniques. More broadly, I love creating spectacular experiences by realizing virtual worlds. Most of all, I enjoy working with artists to help them realize their vision.
