My laboratory focuses on chromatin remodeling factors, which utilize the energy of ATP to slide, remodel, or assemble nucleosomes. Understanding the normal function of these proteins is critical since their loss can lead to mis-regulation of the genome and several distinct forms of disease, including cancer.
Molecular modeling as a way of understanding the mechanism of chemical processes with a particular focus on thermally induced rearrangements of organic molecules.
Animal physiology, especially interaction between neural physiology and behavior in crayfish
Insect mating systems � ladybird beetle aggregations
Analysis of animal locomotion (computer aided motion analysis and electro physiology)
Cell and molecular biology
Pre-mRNA splicing in yeast
Lethal ring-Y chromosomes
Satellite divergence and hybrid incompatibility
Effects of selfish B chromosomes
Spiroplasma-induced male killing
Students in my lab work on ecological questions involving coastal marine invertebrates. Past/current projects include:
- The preference of predatory snails for native and nonnative oysters in Newport Bay
- The effect of temperature on the metabolic rates of intertidal animals
- The effects of air and water temperature on the feeding rates of predatory snails
- Using sound to monitor the feeding behavior of predatory snails
- The growth and survival of intertidal barnacles under warm and cool temperatures

I support thesis research by science students interested in a variety of disciplines in Earth Science or Geology, especially geomorphology, soil genesis, soil mineralogy, GIS-based mapping, and paleoenvironmental reconstructions. Field and/or laboratory project topics (proportions of Environmental Science, Geology, Chemistry, Physics, and Biology are flexible) might include:
- Field and GIS mapping of soil-geomorphology and floral biogeography (Geomorphology/Ecology)
- Experimental soil genesis (Geochemistry)
- Mineral stability experiments (Geochemistry)
- Optical and/or scanning electron microscope (SEM) analysis and interpretation of soil/paleosol microstructures (Micromorphology)
- Clay mineral analyses
Cancer chemotherapy using conventional and less conventional approaches
Drug resistance in tumor cells
The bacterium, Proteus mirabilis, can move rapidly on a solid surface and while doing so forms cells that are ~40x longer than normal. Understanding how these extra-long cells are formed and maintained will improve our understanding of bacterial physiology.

1. Cell signaling for the interplay between cell-division cycle and gene expression events such as pre-mRNA processing in eukaryotes involving several protein kinases including Dsk1p and Kic1p.
2. Genes required for the cellular sensitivity and resistance to platinum-based anticancer drugs.
3. Response networks for environmental phenol stress factors
