B.Sc., University of Sussex in Biology, 1968.
Ph.D., Cornell University in Genetics, 1972.
Biology faculty of Reed College, 1972–2011. Specialties: genetics and molecular genetics.
Professor of Biology Emeritus, 2011-present.
I taught an upper-division genetics lecture/laboratory course, a molecular biology of the gene seminar course, a molecular virology seminar course, and advised senior thesis research students and independent research students.
Related to my teaching, I am the author of a genetics textbook that has gone through eight editions. The present edition is iGENETICS: A MOLECULAR APPROACH (3e) ((c) 2010, Pearson–Benjamin/Cummings). A related version is iGENETICS: A MENDELIAN APPROACH (1e) ( (c) 2006, Pearson–Benjamin/Cummings). I am also one of the authors of an introductory biology textbook, BIOLOGY: A DYNAMIC SCIENCE (3e), by Peter Russell, Paul Hertz, and Beverly McMillan ((c) 2014, Brooks/Cole Cengage Learning). Covers of the books are below.
We were a molecular genetics lab using budding yeast, Saccharomyces cerevisiae, as a model host to identify and characterize host genes involved in pathogenic RNA plant virus gene expression and replication.
Our general research goal was to obtain an understanding of virus-host interactions at the molecular level. We studied Barley yellow dwarf virus (BYDV), which is a plant pathogenic, single-stranded RNA virus. Our primary research focuses were: 1) to identify and characterize host genes for the virus sequence-programmed stop-codon readthrough event involved in expression of the capsid proteins of this virus; and 2) to establish a replication system in yeast with which to identify host gene for viral genome replication.
