Preparation for Allele Swapping

This summer, I am researching possible mechanisms behind speciation in the yeast Saccharomyces paradoxus. I hope to determine if the evolution of sexual adhesin genes, which are required for sexual reproduction, drives speciation. Recently, there was a migration of a Saccharomyces paradoxus population from Europe to North America. This migrant population has displayed evidence of speciation in its mating preferences. In my project, I am analyzing the mating behaviors of North American, European and migrant strains after switching sexual adhesin alleles among the different populations.

Looking at Viruses and Bacteria in Water Column Samples

I am currently on my third week of research, and for the most part I have been processing nice months of water samples that I collected during the past school year. My project focuses on viral ecology in streams; specifically if viral community composition and abundance changes over time and space and how they infect bacterial biofilms on streambeds. Beginning in October of 2016, I have sampled the Crim Dell Stream on campus at three locations (named CDP, CDU, and CDL) every month. That has amounted to twenty-seven water column samples that I have spent the last two and a half weeks working with.
