Professor and Chair
Computer Science Department
500 College Ave.
Swarthmore, PA 19081
I am a Full Professor and Chair of the Computer Science Department at Swarthmore
I also participate in the interdisciplinary program Cognitive
Science. 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 where
the goal is to create intelligent robots by allowing them to go
through a developmental process, rather than being directly programmed
to solve a particular task. By endowing a robot with an appropriate
control architecture and adaptive mechanisms, it can learn through
interactions with the world, developing its own knowledge about itself
and its environment.
