Experience

1. Universidade do Algarve: Algarve, Portugal - March 2001 to Oct 2001: Post-Doctoral Researcher

Post-doctoral research focused on reproductive ecology of Fucus vesiculosus and F. spiralis: comparing external fertilization success, timing of gamete release, gamete dispersal, recruitment, and post-recruitment mortality of two congeners with different reproductive strategies along a wave exposure gradient using manipulative experiments and natural populations. Laboratory work entailed evaluating amount of time for zygote adhesion, and gamete dispersal under controlled conditions. Co-authored a grant (in review) to study selection at biogeographic boundaries of marine primary producers.

2. CICESE, Dept. Ecology: Ensenada, Mexico - January 2001 to present: Associate Professor

Associate Researcher/Professor (Investigador Asociado C) – Division of Oceanology, Dept. of Ecology. Research focuses on kelp forest resources as part of the fisheries ecology group, physical-biological coupling in the kelp forest ecosystem (ENSO and global change), kelp-urchin-abalone interactions, and spore and larvae dispersal. Responsible for advising graduate students, conducting independent research, and for teaching graduate courses in marine ecology. Responsible for three main graduate classes: 1) Molecular Ecology, 2) Kelp Forest Ecology, and 3) Rocky Shore Ecology. Principal investigator of three grants: 1) "Biological-Physical Coupling in the Kelp Forests of Baja California", 2) "Molecular Ecology of Kelp Forest Resources", and 3) "Speciation in Marine Algae at their Distributional Limits".

3. Universidad Autónoma de Baja California - January 1995 to December 2000: Doctoral Student and Undergraduate Lecturer

4. Non-profit, Environmental, and Part-time work - December 1992 to December 1994

5. University of Southern California – Dept. Bioc. & Mol. Biology - August 1991 to December 1992
