David C. Smith
Professor of Oceanography
Associate Dean, Graduate School of Oceanography
CIB 227
(401) 874-6172

Educational Background

Scripps Institution of Oceanography (UCSD)
California State University, Long Beach

Areas of Specialization


David Smith's current research interests include marine microbial ecology, particularly the microbiology of deeply buried marine sediments.


David Smith currently teaches a graduate level course in marine microbial ecology (OCG 576), an introductory level course for marine biology freshmen (BIO 130), and co-teaches an upper level undergraduate general oceanography course (OCG 451)
