My research focuses on molecular evolution and ecological genetics. I am primarily interested in speciation, adaptation genetics, and mutation dynamics. My previous studies have involved laboratory research, manipulative field experiments, and computational approaches. I am more interested in concepts than organisms, and I have worked with plants, insects, and bacteria. I typically take mathematical models and test them under experimental conditions.
Current interests include using a candidate gene approach to study restricted dispersal and philopatry in the cryptic insect species complex Enchenopa binotata, testing predictions from adaptive landscape models in plants, and investigating the qualitative predictability of phenotypic noise and its role in adaptation.
I am also involved with the SEA-Phages program for Intro Biology 113. This engages students in authentic research experiences discovery novel bacteriophage. I am interested in pursuing research into phage host diversity, applying my previous work with host plant shifts in phytophagous insects to investigating when phage shift to novel bacterial hosts and diverge vs extending their host range. This initiative will help inform attempts to use phage therapy as an alternative to antibiotics as a way to mitigate the increasing problem of antibiotic resistance.
All of my projects can be completed in one or two academic years, and I encourage my students to submit small grants, present at local conferences, and to work towards producing results to be published in the scientific literature.
