My primary research interests are in building a machine that solves problems that human solve, in a mostly human-like way. More specifically, I am working on a movement of eye movement and motor control in reading that adapts to the joint constraints of task, payoff, and individual cognitive architecture. At the moment this means a model that maintains probabilistic beliefs over the possible structures of the strings it reads, and conditions its behavior based on that information to maximize some precise task goal.
In the past I have worked on understanding the emergence of langauge as a communicative system, music perception, and questions of memory interence in sentence processing. I am also a methods and methodology geek, having done work in behavioral methods, eyetracking, ERP, and MEG, as well as borrowing from the stats and AI toolbox whenever I can get away with it.
Reproducible Analysis and Literate Programming
I am a strong proponent of reproducible analysis and research. While I currently don't have the time to proactively post all my data, analysis, and simulation code here, I will provide data, analysis and simulation code for any of the below upon request, assuming it is my code (otherwise it is up to my co-authors). Moreover, I will make sure it is reasonably well-documented and do my best to help you understand it and get it running, within reason. You are invited to build on and modify my work, on the condition that modified variants are similarly shared and I get properly attributed.
