Research
I'm creating new animation tools that provide sketch/multitouch-based interfaces and that build upon new shape and motion representations.
Other Interests
- image/shape correspondence and warping
- organic patterns and forms / generative art
- user-interaction with optimization processes
- polygonal mesh representations
