Roxanne Hayes

PhD Candidate

Email: roxanne.hayes@louisville.edu

Education: BA and MA in Anthropology at the University of Louisville

Research Interests: Through my experiences as both a biological anthropology and molecular biology graduate student, I have remained fascinated by the flow of genetic information through time and across geological space. My research focus moved from human population genetics to functional genetics in fungi but there has always been an underlying interest in the factors that shape genomes. My dissertation topic will focus on the genetic basis of infection strategies that smut fungi use to infect their plant hosts.

PhD Student

Email: andrew.seiler@louisville.edu

Education: B.S. in Biology, A.A. in Chemistry, Thomas More University

Research Interests: I am interested in the fall of arthropods from tree canopies (“arthropod rain”) and the fates of those fallen arthropods (climbing back to tree canopies, falling prey to other organisms, etc.). I will quantify the amount and composition of arthropod rain, then conduct elemental analyses of carbon, nitrogen, and phosphorus. This will allow me to investigate the role arthropod rain plays in nutrient cycling in forest ecosystems.
