Field Experience:

Have served as Chief Scientist or Co-Chief Scientist on thirty-seven expeditions, including eight submersible and five ROV campaigns.

Participated in ALVIN-LULU/AII expeditions in 1977 and 1978 off the East Coast of the U.S., in 1980, 1981, and 1985 on the Cocos-Nazca plate boundary, in 1984, 1987 and 1988, 1990 and 1991, 1993, and 1994 on the Juan de Fuca Ridge, Northeast Pacific. Observer on fifty-nine ALVIN dives and more than twenty dives on other submersibles.

Recent Professional Activities:

Co-Guest Editor, Special Section of Journal of Geophysical Research on "Volcanic and Hydrothermal Processes at the Southern Juan de Fuca Ridge", in March, 1994 issue.

Member of NSF RIDGE Steering Committee- 1995 to present

Member of working group for NSF RIDGE Observatory Experiment

Member of working group for NSF RIDGE Event Detection and Response

Member of American Association for the Advancement of Science and the American Geophysical Union

Current Research Interests:

(1) Relationships between tectonics, volcanic and hydrothermal processes on seafloor
spreading centers, concentrating on the Juan de Fuca Ridge off Oregon/Washington.

(2) Structure and tectonics of transform fault zones.
