Education

1977-1981 Molecular Biophysics Program at Florida State University, Tallahassee, FL. Ph.D. in Molecular Biophysics awarded in December 1981.
1974-1977 Boston College, Chestnut Hill, MA. Graduated cum laude with B.S. in Biological Science, May 1977.

Professional Experience

August 2005 – present
Interim Associate Dean for Undergraduate Academic Programs, College of Biological Sciences
July 1998 – present
Professor, Section of Plant Biology (primary affiliation) and Section of Molecular & Cellular Biology (secondary affiliation), University of California, Davis, CA.
October 2001 – January 2003
Interim Chair, Section of Plant Biology, University of California, Davis, CA.
July 1994-June 1998
Associate Professor, Sections of Plant Biology and Molecular & Cellular Biology, University of California, Davis, CA.
Sept. 1988-June 1994
Assistant Professor, Department of Botany, University of California, Davis, CA.
Aug. 1986-Aug. 1988
Postdoctoral research associate with Professors B.R. Selman in the Department of Biochemistry, and K. Keegstra in the Department of Botany, University of Wisconsin.
Feb. 1983-Aug. 1986
Postdoctoral research associate with Professor R.A. Dilley in the Department of Biological Sciences, Purdue University. Projects involved investigations of the involvement of protons in a nonequilibrating pool in the thylakoid membrane with the backreactions in photosystem II and with ATP synthesis. Other projects were concerned with the location of the lesions in the electron transport chain produced by chloride depletion and photoinhibition.
Oct. 1981-Dec. 1982
Postdoctoral research associate with Professor W. Junge in the Department of Biophysics, Universitaet Osnabrueck, Osnabrueck, Federal Republic of Germany. Project involved investigation of flash-induced proton deposition into chloroplasts by photosystem II, and the influence of low concentrations of uncouplers thereon.
Sept. 1977-Oct. 1981
Graduate Research Assistant with Professor P.H. Homann in the Institute of Molecular Biophysics, Florida State University. Thesis, entitled "Studies on the composition and organization of the oxidizing side of photosystem II in chloroplasts", involved investigation of electron transport in and around photosystem II of green plants, including the requirements for chloride and manganese, and the arrangement of light harvesting pigments around the photosystem II reaction center.
