Department of Computer Science
I am on family leave from Grinnell College during the spring 2013
semester. While I do not have regular office hours, I will be
responding to email periodically and hope to be available for
occasional advising appointments.
I am interested in visual learning, especially inducing properties of
the environment, i.e. what are relevant features? what is an
appropriate model of reasoning for a visual task? Typically this
involves bringing many sources of information to bear on a problem and
using them in a unified fashion.
More details may be found in my research projects or publications
