The following list provides some examples of topics on which faculty in Ecology and Evolutionary Biology at the University of Tennessee, Knoxville, would be interested in recruiting graduate students for entry in August 2019.
This list is not exhaustive – indeed, far from it. There are other faculty members who will be recruiting students in the Department. Also, the listed faculty members may recruit students who have different interests to those listed. But we prepared this list just to illustrate to prospective students some of the diversity of topics on which we envision recruiting, spanning conservation, macroevolution, global change ecology, molecular genetics, biology education, and systematics, among many other topics.

- How do assembly costs and translation errors shape selection on codon usage and how do they play themselves out in the face of biased mutation and genetic drift?
- Some pathogens replicate intracellularly within hosts and move between host cells through budding or bursting. How does the rate of intracellular replication affect the rates of immune response clearance by the host? How, in turn, does this lead to changes in the survival of the host and transmission of the pathogen between hosts?
Lou Gross (tiem.utk.edu/~gross/)
- How are biological processes integrated across scales and levels of biological resolution from within organism level to those operating at population/community/landscape levels?

Susan Kalisz (kaliszlab.weebly.com)
- How do invaders and antagonistic interactions alter soil fungal communities, the function of key plant mutualisms and shape the demography and life history evolution of native community members?
- What role does the ecological context, specifically selection driven by the absence of mates and pollinators, play in the evolution of selfing and genomic changes within and between species? Is selfing an evolutionary dead end or a reversible mating system?
