Research Interests

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 from NASA.

Hobbies
My major hobby is my profession, astronomy. I also enjoy classical music, magic (very amateur), tennis, theater, and skiing.
