Thomas R. Waller

Thomas Richard Waller (born 18 July 1937) is an American malacologist and paleontologist.

Waller studied at the University of Wisconsin, where he earned a Bachelor of Science degree in 1959 and a Master of Science degree in 1961. He received his Ph.D. in geology from Columbia University in 1966. In the same year, he joined the Smithsonian Institution in Washington, D.C., where he became Associate Curator, and since 1974 he has served as Curator of Mollusks.

His research focuses on the evolution, ecology, functional morphology, and systematics of bivalves. In 1978, Waller established the bivalve order Limida. His work includes both extant and fossil bivalves, with particular emphasis on scallops (family Pectinidae).

Waller was elected a Fellow of the American Association for the Advancement of Science in 1986 and received the Gilbert Harris Award from the Paleontological Research Institution.
