Research and Teaching Experience

2012-present     Research Scientist (Full), University of California Los Angeles, Institute of the Environment and Sustainability, White Mountain Research Center.  Research center and appointment transferred from UC San Diego to UCLA.  Continued development of research program.

2001-11       Associate Research Scientist, University of California San Diego, White Mountain Research Station. Primarily research but some teaching: NSF REU and WMRS intern programs; wilderness skills; visiting professor teaching invertebrate zoology at the University of Puerto Rico (2002); served on graduate committees and advised undergraduates.

1995-2001   Tenured Associate Professor, Dept. of Marine Sciences, University of Puerto Rico. Teaching: Community Ecology, Invertebrate Zoology, and co-taught a Technical Presentations course; started and ran departmental seminar series. Invertebrate museum curator.  Graduate students advised.

1992-95       Assistant Professor, Dept. Marine Science, University of Puerto Rico. See above.

1987-92       Research and teaching assistant, Florida State University. Projects: 1) Experimental design for test of effects of shifting water color on submerged aquatic vegetation, 2) Climate trends as a function of wetland drainage. Teaching: Invertebrate Zoology, Animal Diversity (including some honors sections).

1987           Project technician, S. Florida Research Center, Everglades National Park. Seagrass microhabitat characteristics and crustacean and fish distribution.

1983-86       Research Associate, National Audubon Society Research Dept.  Ecology of seagrasses and associated fauna at several scales.

1981-83       Science Instructor/Science Director at Newfound Harbor Marine Institute/Seacamp, respectively.  Marine field education, middle school though undergraduate.

1979-80       Teaching assistant, Ohio State University. Evolution, Introductory Biology.
