As Director of Penn State Behrend's
School of Science, much of my time is spent working with faculty and
students in biology, chemistry, computer science, geosciences, mathematics,
and physics. Our focus is on providing first-rate science and mathematics
experience for students in the classroom and laboratory, based on a strong
tradition of excellence in teaching by faculty at Penn State Behrend. New
science programs added or expanded in recent years include molecular biology,
computer networking, biomathematics, bioinformatics, environmental studies,
statistics, grannular flow, computational physics, and secondary education.
Cooperative agreements with medical schools and colleges have opened new
opportunities in pre-medicine, pre-dentistry, pre-pharmacy, and secondary
education. Penn State-Behrend trains graduates for admission to major
graduate and professional schools, or to obtain professional positions
in business and industry.
In my research, I am interested in
astrophysical problems related to the origins of solar systems,
interstellar matter, and the search for life in the universe. Using
primarily techniques of infrared astronomy, my students, coworkers, and
I have studied comets and the atmospheres of the giant planets. Another
interest is in environments of disks and planetary systems around other
stars. We observe with telescopes on Mauna Kea, Hawaii and other sites.
I'm a member of the Solar System Science Team of the ESA Infrared Space
Observatory (ISO), an infrared telescope in earth-orbit. I have served on
various NASA and NSF committees, including the Keck Observatory NASA
Telescope Allocation Committee. Our research is funded through grants
