I am a third year doctoral student at UC Berkeley in computer science (specialization: artificial intelligence). I mainly work in the Computational Cognitive Science lab, and I'm advised by Tom Griffiths and Dan Klein. My research focuses on Bayesian modeling of psychological and linguistic processes. My current focus is on models of pedagogy: how can we model teaching and learning in order to best predict what examples and problems will result in the most learning? Models of pedagogy are also relevant for intelligent tutoring systems, and we hope to apply our techniques to improve these systems. Additionally, we look at how our models of pedagogy compare to human performance on teaching and learning tasks. My other work at Berkeley has primarily involved experimental and theoretical work on language evolution and iterated learning.
I completed my undergraduate and masters' work at Stanford in Symbolic Systems, and following graduation, I worked in Stanford's Natural Language Processing Group as a research programmer for Professor Chris Manning. My master's thesis involved creating computational models of students' learning in intelligent tutoring systems, and I was advised by Professor Dan Schwartz.
My other interests include feminist activism and improving access to science and math education for women and girls. I teach science once a week at Girls Inc., working with girls ages 6-14. I am originally from northern Minnesota and miss having a lake in my backyard - but the lack of snow in the Bay Area is a plus! Other interests include jigsaw puzzles, rollerblading and hiking, sci-fi books, and SET.
