Dr. Reggie L. Hudson Professor of Chemistry Office: SHC-210 (727) 864-8457 hudsonrl@eckerd.edu Dr. Hudson earned his bachelor's degree, with majors in mathematics and chemistry, from Pfeiffer College and his Ph.D. from the University of Tennessee. Since coming to Eckerd College in 1978 he has done research in conjunction with scientists at University College London and at NASA's Goddard Space Flight Center. His main research activities now involve cometary and interstellar chemistry, particularly the influence of high-energy radiation on cometary surfaces, icy satellites of the outer planets, and interstellar matter. He teaches the junior-year physical chemistry courses at Eckerd, freshman chemistry courses, and Eckerd's astronomy and astrobiology courses.
