Professor and Chair
Computer Science Department
500 College Ave.
Swarthmore, PA 19081
I am a Full Professor and Chair of the Computer Science Department.
I also participate in the interdisciplinary program Cognitive
Science at Swarthmore
College. I received my Ph.D. in Computer Science with a minor in Cognitive Science from Indiana University in 1994. I
received my B.A. in Mathematics
from Grinnell College in 1985.
My current research is in the field of developmental robotics which
focuses on the autonomous self-organization of general-purpose,
task-independent robot control systems. It takes its inspiration from
developmental psychology and developmental neuroscience.
Developmental robotics explores the kinds of perceptual, cognitive,
and behavioral capabilities that a robot can discover through
self-motivated actions based on its own physical morphology and the
dynamic structure of its environment.
