Research

My lab and I are interested in the evolution of plant morphology. Lab projects include evolution of plant architecture in grasses (Poaceae), developmental genetics of domestication events in foxtail millet and other grasses, and evolution of fruit shape and of seed oils in Paysonia and related mustard species (Brassicaceae). We use phylogenetic, quantitative genetic, developmental genetic, developmental morphological, and, increasingly, phenomic and digital analysis techniques in these analyses.

Research

I have longstanding research interests in the developmental and molecular genetics of multicellular eukaryotes, the establishment of Arabidopsis thaliana as a model organism for plant biology, and the isolation and characterization of embryo-defective mutants of Arabidopsis, which have provided valuable insights into hundreds of essential genes with diverse functions in plant growth and development.  Most recently, my research has focused on the developmental consequences of a loss of chloroplast translation in Arabidopsis and the relationship between genotype and phenotype for an essential protein involved in fatty acid biosynthesis.  I am also interested in human genetics and medical genomics, the emergent fields of genetic testing and personalized medicine, and the complex interactions between genetics, technology, and public policy.  Most urgently, I believe that public policy should be guided whenever possible by scientific evidence, and not by personal or political ideologies.  Because I am retired, I am no longer accepting graduate students into my research program.  But my passion for genetics in particular, and science in general, remains unabated.

Teaching

  

PBIO 5110 Professional Development, fall semesters.
This course provides a foundation of skills needed to succeed in graduate school and prepare for a career following graduation.
 
PBIO 5541 Phylogenomics
Current topics in the theory and application of genome and transcriptome sequencing to phylogenetics, prediction of gene function, and evolution of genes.

Research

The overarching context of my research program is to bridge the understanding that ecologists and evolutionary biologists have gained about how evolution operates within populations and the understanding that systematists and evolutionary biologists have gained about the patterns of biodiversity observed at large spatial and temporal scales. In pursuit of my research goals, I have conducted intensive studies on the phylogenetic relationships of milkweeds (Apocynaceae, Asclepiadoideae), selection on floral traits by pollinators, the dynamics of hybridization driven by variation in floral scent chemistry, and the evolution of defenses against herbivory. My approach emphasizes (1) phylogenetics analyses of plant lineages and (2) the inference and hypothesis testing of evolutionary and ecological processes that produce biological diversity.

Research

I study the determinants of species richness at all spatial scales, from the microcosm to the continent. I have used a variety of methods, including meta-analysis of floristic data, greenhouse microcosms, computer simulations, permanent plot data, and field experiments. Particular projects include an analysis of North American floras, analysis of ordination methods, studies on microcommunities emerging from soil seed banks, the flora of the Tallgrass Prairie Preserve, the vegetation of the Tallgrass Prairie Preserve, the distribution of Costa Rican rain forest trees, analysis of species-area curves, methods for extrapolating biodiversity, applications of fractal geometry, forest dynamics in an old-growth North Carolina forest, succession following catastrophic wind disturbance in Minnesota, and several others.

My two largest projects currently are the Floras of North America Project and the Plant Virus Biodiversity and Ecology project.

Research

My research program is focused on using phylogenomics as a framework to address systematic and evolutionary questions in the Asteraceae, commonly known as the sunflower, daisy, or aster family. I am specifically interested in understanding evolutionary relationships within and among the clade comprised of Tribes Anthemideae, Astereae, Calenduleae, Gnaphalieae, and Senecioneae. This lineage has its origin in Africa before extensive migrations worldwide and diversification. I am particularly interested in understanding patterns of historical biogeography, species diversifications, and whole genome duplications in a paleoclimate context.

Research

My core interests are in the area of algal stress physiology and algal biofuels.

Current research focuses on the project Continuous Cultures of Algae: Basic Research Toward Biofuels funded by the Oklahoma Center for the Advancement of Science and Technology (OCAST). We are exposing pure and mixed cultures of salt tolerant green algae, diatoms and cyanobacteria to variable temperature, salinity, and nutrients to test the hypotheses that mixtures of the algal classes will maintain higher biomass, productivity and yields of neutral lipids (the direct feedstock for biodiesel) compared to monocultures. Longer term goals include (1) design of process control mechanisms and algorithms based on an empirical understanding of community dynamics and algal physiology derived from this project, and (2) scale-up to outdoor mesocosms.

Recent past research focused on the phylogeny and physiological ecology of broadly halotolerant algae and cyanobacteria from the Salt Plains National Wildlife Refuge near Cherokee in northwestern Oklahoma. This work comprised two NSF-funded projects:

Collaborative Research: Salt Plains Microbial Observatory(MCB-0132097).

LExEn: Response of photosynthetic microbes of the Salt Plains National Wildlife Refuge to dynamic extreme conditions (MCB-9978203).

Current research directions and possible thesis/dissertation topics include:

Growing algae for biofuels: optimizing growth and yield conditions, comparing productivity/yields and/or stablility of pure single isolates vs. communities of mixed genetic strains (addresses fundamental ecological concepts)

Global phylogeography of the halophilic alga Dunaliella (addresses fundamental ecological concepts)

Demonstrating and characterizing obligate or facultative interactions between (halophilic) algae/cyanobacteria and heterotrophic bacteria/archaea (addresses fundamental ecological concepts)

Characterization of putatively primitive isolates of cyanobacteria from the Great Salt Plains: morphology, physiology and molecular genetics

Physiological ecology of aquatic plants and algae/phytoplankton in local lakes and the the Great Salt Plains

Research

I provide research support for the College of Arts and Science. I assist faculty, post docs and students with advice, troubleshooting, and repair on a variety of modern biological instruments. I mainly provide support for the life sciences but also work with other researchers in the College. I am part of the new Biodiversity group in the Henry Bellmon Research Building and work with the faculty and students in that lab with technical issues and general lab management. I help researchers install, write scripts, and use phylogenetic and bioinformatic programs on the high performance computers at OSU. I am also the Facility Manager of the new Advanced Infrared Structural Biology Core Facility.
