Research: I am a molecular ecologist/ conservation biologist with broad interests in quantitative ecology, evolution, and various 'genomics' (i.e., meta-, phylo-, and conservation). Much research in our lab focuses on the genetic variation found in communities, species, populations and metapopulations, and the manner by which it is impacted by historical and contemporary habitat fragmentation (where connectivity is defined as the amount of gene flow — or effective dispersal — amongst habitats). To do so, we derive and analyze ‘legacy’ molecular markers [i.e., microsatellite (msat) fragments] and those more contemporary [i.e., single nucleotide polymorphisms (SNPs)] that identify migrants, define corridors, and gauge the potential for adaptive management (such as assisted migration). Our taxonomic focus is broad, and includes endangered, threatened and relictual species (i.e., with smaller population sizes), as well as those with distributions more global. We also work actively with invasive species and use molecular tools to quantify the biodiversity of parasitic helminths.
Student projects employ next generation sequencing strategies to identify thousands of informative SNPs spanning the entire genomes of diverse study species. For example, one project identifies those genomic regions evolving under natural selection in a broadly distributed North American freshwater minnow (Speckled Dace, Rhinichthys osculus). A second develops SNP panels that diagnose and characterize admixture among endemic freshwater fishes (genus Gila) and their introduced, non-native relatives in the Colorado River of western North America. A third detects signatures of selection among adaptively divergent radiations of freshwater suckers (Catostomidae).
Others characterize microbiomes of freshwater streams impacted by fracking, quantify movements of invasive Brown Tree Snake (Colubridae, Boiga irregularis) in Guam using SNPs as molecular tags, and assay zones of hybridization/ introgression in North American Box Turtles (genus Terrapene). Each project operates at the population level and generates data at the terabyte scale. All share an inordinate reliance upon resources at the Arkansas High Performance Computing Center (AHPCC). Expectations focus on timely completion of computationally intensive tasks such as de novo aligning of ‘reads,’ parsing/ analyzing thousands of loci across hundreds of samples, and deriving phylogenomic inferences from massive SNP supermatrices.
Outreach: We also utilize our molecular markers to decipher the long, convoluted history of the North American biota, and to devise adaptive management scenarios that conserve its genetic variability within regions and across landscapes. We interact closely with applied conservation practitioners, thus ensuring that our broad, multidisciplinary research reflects the best science available, and that our managerial recommendations are adaptive, relevant, and sustainable.
Education: Our research approach transects multiple disciplines and embraces cutting-edge technologies. We employ them to instruct a new generation of scientist in the theories and methods of biodiversity recognition, definition, conservation, and restoration. We are committed to these goals and believe our stewardship will help motivate students, colleagues, and cooperators as we move into an uncertain future.
