Callum crop

Callum J. Bell, Ph.D., President

In addition to leading the organization, Dr. Bell has two main research interests. He provides technical leadership to a collaboration with Washington State University funded by the National Science Foundation to understand the genome of red alder and its symbiosis with the nitrogen-fixing bacterium, Frankia alni. This project aims to understand the complex interactions among tree genes, bacterial strains, soil types, and microbial communities, and how these influence growth of this important tree crop, which is used for many timber applications and as a biofuel. Another project, funded by the Gordon and Betty Moore Foundation, aims to develop technology to enable transcriptome studies of individual plant cells. Plant cell walls present challenges to single cell studies that are not encountered in animal investigations. This project aims to bring the benefits of single cell biology to plant researchers. Dr. Bell received his Ph.D. From the University of Edinburgh where he carried out pioneering work on the gravitational biology of Arabidopsis thaliana.   


Andrew crop

Andrew Farmer, Bioinformatics Fellow

Mr. Farmer's work focuses on the use of bioinformatics to address questions in plant biology, with an emphasis on enabling crop improvement efforts though the development of clade-oriented information resources utilizing phylogenetic and comparative genomic analyses. He leads NCGR participation in the USDA-funded  Legume Information System ( as a collaborative effort with partners at Iowa State University and USDA-ARS. He also serves as co-PI on an NSF-funded grant to develop a federation of independently developed and separately maintained web-based genomic data resources in the legume family, the Legume Federation ( His current research interests are focused on how plant species have adapted to a wide range of environments through diversification mechanisms associated with large scale genome duplications, while at the same time maintaining core functions. He participates in a variety  of open source  software development  projects and in other efforts to facilitate data sharing and improving adherence to standards among groups involved in information resource management in plant biology.   


Joann crop

Joann Mudge, Ph.D., Senior Research Scientist

Dr. Joann Mudge works on structural genomics, studying how genomes are organized and how genome structure affects gene expression, phenotypes, and genomic plasticity. Her main area of focus is in plant genetics, especially of nitrogen-fixing species in the bean and pea family (legumes). Her current projects include de novo sequencing, assembly and analysis of multiple genomes in Medicago truncatula and its relative, alfalfa. She also has a project on pangenomics algorithm development and is applying these algorithms to gain biological insights in multi-genome datasets, including Medicago truncatula. In addition, she works in the area of plant microbiomes, especially looking at plant/fungal interactions that buffer plant growth against abiotic stressors and implications for climate change. Dr. Mudge has also worked in human genomics, playing a major role in the sequencing of the 6th ever human genome (of a Korean individual) and of female monozygotic twins discordant for multiple sclerosis. Dr. Mudge is also dedicated to outreach and helping the upcoming generation to develop an interest in science. An NIH-supported project allows her to work with elementary and secondary education teachers to teach them about genomics and bioinformatics and to help them develop computer-based case studies for their classrooms. She also has an innovative high school intern program in which she works with high school students, teaching them about DNA sequencing and bioinformatics and helping them to develop case studies. She regularly visits schools and science fairs to teach and promote science.

Stephanie crop

Stephanie Guida, Ph.D., Senior Bioinformatics Analyst

Dr. Guida-English’s main research interest is identifying the role of epigenetic mechanisms in human disease. She is currently working with collaborators at the University of Wyoming to study how the obese maternal environment in the model species of ovine influences the regulation of biological pathways in the fetus. The group is also interested in establishing how epigenetic mechanisms are involved in stabilizing the pathways altered in the fetus in response to the maternally obese environment, predisposing offspring and possibly future generations to disease later in life through heritable epigenetic marks, such as DNA methylation. She has been involved with the Marine Microbial Eukaryotic Transcriptome Sequencing Project (MMETSP), a large effort funded by the Gordon and Betty Moore Foundation to sequence, assemble, and annotate nearly 700 diverse marine microbial eukaryote transcriptomes. Through a collaboration with Northwest Advanced Renewables Alliance (NARA), she has also assisted in the development of a Douglas Fir SNP chip to aid in forestry breeding programs.

 NCGR Adjunct Faculty

GregMayGreg D. May, Ph.D.,  Research Fellow

Dr. May’s interests are in the understanding of the recruitment of genes to serve new biological functions and in the biology of the genome.  When novel organs or biological functions such as vision evolve, genes are often recruited to serve new purposes. Lens proteins in the eye, for example, were recruited from metabolic enzymes and in some instances still retain metabolic activity. Plant genome duplication or increased ploidy facilitates genome plasticity and the opportunity for genes to be recruited to serve novel functional roles. The effect of these duplication events on the biology of the genome, in particular, the molecular mechanisms, such as DNA methylation and histone modification employed to compensate for changes in genome content are also of interest.

Craig BCraig Beattie, Ph.D., Program Leader

Dr. Beattie works on the structural and functional genomics of pathogen entry into eukaryotic cells, the genetics of disease susceptibility in multiple mammalian species, and structural and comparative genomics. The subjects of his research include commercial animal species where his group’s efforts led to the first comprehensive genomic and sequence maps for livestock as well as the discovery of unique, clinically active agents for use in human and veterinary medicine. His current research is focused on applying RNA-seq to identify structural differences in differentially expressed gene clusters and potential allelic imbalances relevant to host susceptibility to disease and the etiology of infection, and computational modeling of pathogen entry and neutralization to improve vaccine development. 

FieldsMatthew Fields, Ph.D.  Research Fellow

Dr. Matthew Fields is an associate professor in the Department of Microbiology at Montana State University.  His lab is in the Center for Biofilm Engineering, and he is also associated with the Thermal Biology Institute and the Energy Research Institute at Montana State University.  His laboratory uses molecular ecology to study microbial communities associated with different environments in the field that include subsurface sediments, groundwater, coal, and industrial environments. Laboratory work includes sulfate-reducing bacteria, methanogens, and lipid-producing algae, and these types of organisms are important to bioremediation, metal corrosion, and biofuel production, respectively.  Ultimately, a driving question is to understand the relationships between structure and function at different scales of biology and how ecological and physiological responses help shape the structure and function relationships. An improved understanding of structure/function relationships will allow predictive modeling and design for a variety of natural and engineered systems.
