Research Summary
My training in biological research includes study of cell differentiation in cell cultures of vertebrate muscle, but more extensive work in both plant and algal cell biology. Most recently my laboratory has examined the nature, quantity and mode of distribution of DNA genomes of mitochondria and plastids. The second area of laboratory concentration concerns the species problem, how separate species evolve. The work examines particular species and genera of the volvocales, freshwater green algae, brown algae, and abalones, and the analysis includes mating compatibility, chromosome number, and DNA relatedness as determined by sequencing.
In terms of teaching, I have taught courses in subjects ranging from birds to bacteria, and a freshman to advanced graduate student level. I have also taught summer courses for high school teachers, and molecular biology laboratory courses for postdoctoral students at Friday Harbor Marine Laboratory and at the University of Concepcion, Chile.
