Catherine Lai

Me! I'm a graduate student in the Department of Linguistics at the University of Pennsylvania. You can mainly find me in the phonetics lab where I take advice from Jiahong Yuan and many other people. I'm interested in the phonetics-semantics-pragmatics interface, which really means that I am interested in speech prosody. I hope that looking at the interactions in these areas can provide some bridging between the symbolic and probabilistic aspects of language. More generally, I'm interested in how you can compute these sorts of things. You can find out all about our work in the phonetics lab by coming to splunch, our weekly speech research lunch.

I'm also interested in computational models of language change (see the working paper below). I'm willing to admit that I'm a bit of Bayesian, but if you're going to be a Bayesian you have to think about utility functions. (I know an alarming number of economists)

Not too long ago, I did a research masters at the University of Melbourne, Australia. I was part of the Language Technology Group and my advisor was Steven Bird. Back in the day, I researched querying and manipulating linguistically annotated data. (ie. trees).

Besides this, I am a strong supporter of the work of Amnesty International.
