Ph.D., University of Montana
My research is focused on the empirical study of adaptation in natural populations. I am particularly interested in how trade-offs are resolved during the process of adaptive evolution in life history, behavioral, and physiological traits. We use a variety of field and lab techniques to test and develop theory while also striving to understand the natural history of the organisms we study.

I am interested in the evolutionary ecology of parasite-host interactions. I study the effects of parasites on animal behavior, as well as the effects of parasites on other parasites in communities.

Rachel Mueller
Rachel Mueller - Associate Professor
Ph.D., University of California, Berkeley
I am interested in three basic questions in evolutionary biology: (1) How do genomes evolve, particularly those at the extremes of genome size? (2) How do transposable elements shape genome biology and evolution? (3) How does genome size impact phenotype and the evolutionary trajectories of lineages?

Dhruba Naug
Dhruba Naug - Professor
I combine my interests in behavioral and cognitive ecology to understand the functioning of individuals and social groups. My research involves experimental work in behavior and physiology complemented by approaches based on individual based modeling.

Jennifer Neuwald
Jennifer Neuwald - Special Assistant Professor
Ph.D., Washington University in St. Louis
I am an evolutionary ecologist interested in using a multidisciplinary approach to investigate how environmental variation and evolutionary processes converge to influence the patterns of demographic, genetic, and genomic variation in natural populations, especially those of conservation concern.

Elizabeth Pilon-Smits
Elizabeth Pilon-Smits - Professor
Ph.D., Utrecht University, The Netherlands
In the Pilon-Smits lab we are interested in processes by which plants accumulate and detoxify environmental pollutants, as well as in ecological and evolutionary aspects of selenium hyperaccumulation. We study these processes from the molecular level to the field. Our approaches include genomics, genetics, biotechnology, biochemistry, whole-plant physiology, and ecological studies. These studies are aimed to gain knowledge about basic biological processes, but have applications for the use of plants for environmental cleanup or as fortified foods.

Ph.D., Colorado State University
My research interests are guided by the broad consideration of how ecological processes and patterns are constrained by habitat structure and environmental variability at multiple scales in aquatic ecosystems. Our results provide a basis for predicting aquatic community attributes at geographic scales and for ecological responses to land-use alterations and regional climate changes.

A.S.N. Reddy
A.S.N. Reddy - Professor
Ph.D., Jawaharlal Nehru University
One of the fundamental questions in plant biology is how plants sense and respond to environmental (abiotic and biotic) and hormonal signals that regulate diverse cellular processes and various aspects of plant growth and development. Our group has been studying i) calcium-mediated signal transduction mechanisms with emphasis on calcium sensors and their target proteins, ii) mechanisms that regulate basic and alternative splicing of pre-messenger RNAs in response to stresses, iii) disease resistance, iv) cell wall degrading enzymes for biofuel production and iv) synthetic signal transduction circuits in plants. We use molecular, cell biological, genetic, biochemical, bioinformatics and computational tools to accomplish our research goals. Arabidopsis, maize, potato and Miscanthus are used in our research. Studies on computational aspects of alternative splicing and protein-protein interactions are being done in collaboration with Asa Ben-Hur in the Department of Computer Science at CSU (http://www.cs.colostate.edu/~asa/projects.html).

Kristen Ruegg
Kristen Ruegg - Assistant Professor
PhD, University of California, Berkeley
My research is focused on ecological and evolutionary genomics in a changing world.  I am co-director of the Bird Genoscape Project, a large, multi-institutional effort to use genomic methods to facilitate migratory bird conservation. As part of this effort we are addressing questions such as: 1) How are genetically distinct populations connected across breeding, migratory and wintering areas, 2) What is the role of migration in generating avian diversity? and 3) Which populations will have to adapt most to keep pace with climate change?

Mark Simmons
Mark Simmons - Professor and Curator of the Charles Maurer Herbarium
Ph.D., Cornell University
My research program consists of two interrelated components: phylogeny and taxonomy of the flowering-plant family Celastraceae (spindle-tree family), and conceptual aspects of molecular phylogenetics. Molecular phylogenetics uses genomic data (typically DNA sequences) to reconstruct evolutionary relationships among species. This field is playing an increasingly central role in biology, from inferring the diversification of multigene families, to tracking invasive species, conservation of protected species, as evidence in criminal investigations, and fighting bioterrorism.

Dan Sloan
Dan Sloan - Assistant Professor
Ph.D. University of Virginia
My research investigates the evolutionary forces that create diversity in genome size, structure, and function. I am particularly interested in the evolution of so-called "resident genomes" that exist inside the cells of another organism, including those of mitochondria and plastids in eukaryotes and endosymbiotic bacteria in many insects. Much of my current work focuses on how these resident genomes co-evolve with the host genome.

Melinda Smith
Melinda Smith - Professor, Director Semi-arid Grassland Research Center
Ph.D., Kansas State University
My research focuses on understanding the consequences of human-caused global changes, especially the impacts of climatic changes, biological invasions, eutrophication (e.g., increased N deposition), and altered disturbance regimes for biodiversity and ecosystem structure and function. Within this context, my research addresses questions about the functional roles of species in ecosystems, the causes and impacts of loss and gain of genetic and species diversity, the factors that influence species coexistence and patterns of species abundance, and the relative strength of bottom-up (resources) vs. top-down (consumers) controls in structuring communities. My research employs a mixture of empirical approaches (observational, experimental, comparative and synthetic) and utilizes C4-dominated grasslands as experimentally tractable and dynamic model systems.

Ph.D., Ecology & Evolutionary Biology, Cornell University
I study how the atmosphere develops its greenhouse gas composition. In natural ecosystem, this work investigates how the function of ecosystems is structured by the interactions among humans, plants, the soil and soil microbes. In urban ecosystems, I study the human activities that lead to methane emissions.

Diana Wall

Ph.D., University of Kentucky
My research focuses on soil ecology and how soil invertebrate biodiversity influences ecosystem processes. Experimental research in field and lab measures factors affecting distribution patterns of soil animals at small to global scales and their influence on above-belowground linkages. A key aspect is understanding how soil biodiversity contributes to long term sustainability of soil ecosystems.
