We study the causes of cellular trait variation. Our primary system is mating pheromone induced cell differentiation in budding yeasts (i.e. baker’s yeast). We use a broad array of techniques from genome editing to fluorescence microscopy to computer modeling. Much of our work focuses on RNA and protein metabolism. Current student projects include:
- Molecular mechanisms of natural variation in protein production and degradation
- Genomic analysis of RNA interference pathway proteins
- Inhibition of CRISPR Cas-9 by nucleosomes
- Influences of genetic and environmental variables on the kinetics of cell differentiation
- Diversity and substrate specialization of yeast species in Whatcom county (outreach project w/ local middle schools)
