BS: University of Montana, 1976 PhD: North Carolina State University, 1999 Postdoctoral: North Carolina State University. I conduct research on the genetics of life history evolution in plants. The genes responsible for evolution of complex patterns of growth form and resource allocation have key roles in shaping how plants respond to new environments such as those brought about by changing climates. However, these processes have received much less study than those regulating other important adaptive traits such as flowering time. We have been using the rock cress Arabidopsis lyrata as an experimental organism for this research. We have discovered that A lyrata is highly variable in resource allocation properties, and its extensive genomic resources make it uniquely valuable for studying these traits. Mapping of genes affecting variation in complex traits (quantitative trait loci, or QTLs) has provided insights on genetic co-regulation of resource allocation traits and their relationship to fitness in different environments. We have been making and testing models of trait networks in order to gain insights on the cause-effect mechanisms by which QTLs coordinately regulate developmental processes, and thus give rise to correlated patterns of variation in multiple traits. I am interested in providing research opportunities for undergraduates and graduate students who combine mathematical aptitude with curiosity about how genetic variation shapes complex sets of traits.

Characters as Groups: A New Approach to Morphological Characters in Phylogenetic Analysis 2007 1500 A new method for working with morphological characters is described and explored in experiments using human participants. The method uses direct comparison and sorting of images to produce hierarchical character-cladograms. A character-cladogram is a...
Complex Data Produce Better Characters 2004 956 Abstract: Two studies were conducted to explore the use of complex data in character description and hybrid identification. In order to determine if complex data allow the production of better characters, eight groups of plant systematists were given...
Detection of the Dinozoans Pfiesteria piscicida and P. shumwayae: A Review of Detection Methods and Geographic Distribution 2005 462 Molecular methods, including conventional PCR, real-time PCR, denaturing gradient gel electrophoresis, fluorescent fragment detection PCR, and fluorescent in situ hybridization, have all been developed for use in identifying and studying the distribu...
Effects of Causal Networks on the Structure and Stability of Resource Allocation Trait Correlations 2012 179 Discovering the mechanisms by which genetic variation influences phenotypes is integral to understanding life-history evolution. Models describing causal relationships among traits in a developmental hierarchy provide a functional basis for understan...
Game theoretic model of brood parasitism in a dung beetle Onthophagus Taurus 2009 239 We present a game theoretic model of brood parasitism in the dung beetle Onthophagus taurus. Female O. taurus engage in brood parasitism when they attack a brood ball made by another female, destroy the existing egg and place one of their own eggs to...
Genetic Basis of Local Adaptation and Flowering Time Variation in Arabidopsis lyrata 2013 564 Understanding how genetic variation at individual loci contributes to adaptation of populations to different local environments is an important topic in modern evolutionary biology. To date, most evidence has pointed to conditionally neutral quantita...
Local adaptation, phenotypic differentiation and hybrid fitness in diverged natural populations of Arabidopsis lyrata 2011 436 Selection for local adaptation results in genetic differentiation in ecologically important traits. In a perennial, outcrossing model plant Arabidopsis lyrata, several differentiated phenotypic traits contribute to local adaptation, as demonstrated b...
On Deterministic and Stochastic Models of Kleptoparasitism 2009 243 Kleptoparasitism, the stealing of food items, is a common biological phenomenon that has been studied mostly with the help of deterministic dynamics for infinite populations. The infinite population assumption takes the models far from the biological...
Partitioning adaptive differentiation across a patchy landscape: shade avoidance traits in Impatiens capensis 2008 393 Adaptation to different habitat types across a patchy landscape may either arise independently in each patch or occur due to repeated colonization of each patch by the same specialized genotype. We tested whether open- and closed-canopy forms of Impa...
Paths to Selection on Life History Loci in Different Natural Environments Across the Native Range of Arabidopsis thaliana 2013 365 Selection on quantitative trait loci (QTL) may vary among natural environments due to differences in the genetic architecture of traits, environment-specific allelic effects or changes in the direction and magnitude of selection on specific traits. T...
Taxonomy of Pfiesteria (Dinophyceae) 2006 1276 The dinoflagellate species originally described as Pfiesteria shumwayae Glasgow et Burkholder, recently transferred to a new genus, Pseudopfiesteria Litaker et al., is reclassified into the redefined genus Pfiesteria Steidinger et Burkholder, as Pfie...
Timing of shoot development transitions affects degree of perenniality in Arabidopsis lyrata (Brassicaceae) 2015 167 BackgroundPerenniality is best understood in quantitative terms, involving the relationship betweenproduction vs. turnover of meristems, biomass, or energy reserves.
