He has great interest on speech synthesis and speech coding. Take a look at the project Squeak speaks!, that includes an implementation of a Klatt formant synthesizer. He has applied Linear Predictive analysis to speech compression (LPC and RPELTP), speech modification and music synthesis in Squeak.
He worked on physical models for musical instruments, and on a facial animation project, of course all of it in Squeak. He's interested on synthetic characters, facial and body gestures synthesis and avatars.
