I’m interested in understanding the genetic basis of phenotypic plasticity and adaptation, and I’m exploring these processes by integrating genomics, transcriptomics, and epigenomics to identify the loci and networks that underlie environmentally-labile phenotypes..
Ph.D. Candidate, Biology
I am broadly interested in the extent to which organism can modify the environments that they experience through changes in the timing of development. My dissertation research examines how variation in seed dormancy and germination phenology can lead to differences in the environment experienced by seedlings, and tests how differences in the environment in turn alter natural selection on traits expressed across the entire life cycle. I am combining microevolutionary field experiments using the genetic model plant, Arabidopsis thaliana, with macroevolutionary analyses of the evolution of seed dormancy across all seed plants. Additionally, I have a personal interest in natural history of the southeastern US and am performing complimentary experiments characterizing germination phenology and seedling habitat tracking in two native winter annuals, Phacelia fimbriata and P. purshii.
I am an evolutionary ecologist who thinks about connections between living things through transgenerational plasticity and community biotic interactions. I focus my research on parental effects, regulation of this form of transgenerational plasticity through epigenetic mechanisms, and the effect of neighboring community on individuals. I enjoy the combination of field and laboratory experiments to balance controlled manipulations with natural observations. I routinely think about the effect of the environment on things like phenotype and fitness, the influence of parents on offspring, and the effect of community interactions on traits of individuals. I also just really love plants and birds.
Ph.D. Candidate, Biology
I am broadly interested in how stressful and/or variable environments influence plant physiology, phenology, survival, and reproduction. As habitat fragmentation and changing climatic conditions pose mounting threats to plant populations, it is important to learn more about the traits that may ensure survival of individual plants and the population-level effects of those traits. For my dissertation, I plan to investigate how spatial and temporal dispersal influence plant population demography and adaptation. I will use a combination of large-scale field experiments, greenhouse common gardens, phytotron experiments, genetics, and mathematical modeling. Prior to coming to Duke, I did some work with self-incompatibility, polyploidy, plant aging, and demography.
I started working with Kathleen as her Lab Manager in 2016. I received a B.S. in Plant Biology with a specialization in Molecular and Biochemical Physiology from SIUC. I love plants and am interested in how organisms interact with and are affected by changing environments. I am currently working on projects investigating the basis of phenotypic plasticity to further my understanding of how plants adapt to and experience their environment.
