Research Interests:

Current research in my lab focuses on plasticity costs, using vernalization-mediated flowering-time plasticity in Arabidopsis thaliana as our model system. To detect plasticity costs, we have planned a series of parallel lab and field experiments. These experiments exploit parental ecotypes that differ in flowering habit and currently available recombinant inbred (RI) populations developed from these parents. I am learning Quantitative Trait Loci (QTL) mapping so that my students and I can related phenotypic variation in flowering time and detected costs to chromosomal regions and potential candidate genes. We will be very carefully reviewing and possibly revising the design of these experiments, so that we can enhance the insights that can potentially emerge from QTL mapping studies and from the application of other genomic tools.
