LAWRENCEVILLE, NJ -- Dr. David B. Campbell (left) of Langhorne, PA, associate professor of biology at Rider University, has been elected to the office of regional director of mid-Atlantic region for Sigma Xi at organization's recent annual meeting in Arlington, VA.

Sigma Xi, the international honor society for scientific research, has a total of 16 regional directors -- two from each region. These individuals serve on the organization's board of directors. Dr. Campbell will serve a three-year term beginning July 1998.

Sigma Xi provides grants in aid for research to undergraduate and graduate students, publishes American Scientist, and presents awards to outstanding science researchers and science journalists.

A member of the Rider faculty since 1986, Dr. Campbell's research interests include the behavior, ecology, and evolution of marine invertebrates; physiological ecology of invertebrate predators; competition and predation in marine communities; competition between exotic and native species, and systematics of sea stars.

Over the years he has taught coral reef ecology, marine ecology, marine vertebrates, introduction to field marine science (in New Jersey, Maine, and Bermuda), shallow-water habitats of the Florida Keys, general zoology, environmental biology, scientific report preparation, and issues of the New Jersey shoreline.

He has delivered numerous invited lectures, made several presentations at professional meetings, and lists many publications in areas of research interest.

Before coming to Rider, Dr. Campbell served as an assistant professor at the University of Rhode Island, was an adjunct faculty member at the Shoals Marine Laboratory of Cornell University each summer from 1985 to 1993, and also served as an instructor during the summers of 1983 and 1984 for coral reef ecology courses taught in the U.S. Virgin Islands by the School for Field Studies of Beverly, MA.

He earned his Ph.D. in biological sciences from the University of Rhode Island in 1983; his M.S. degree in marine biology from the Florida Institute of Technology in 1978, and his B.S. degree in marine biology.
