The research done in Dr. Larry Forney’s laboratory centers on the diversity and distribution of prokaryotes. Both field and laboratory studies are done to explore the temporal and spatial patterns of community diversity, as well as factors that influence the dynamics of inter- and intra-species competition. In addition research is done to understand how spatial structure and the resulting environmental gradients influence the tempo and trajectory of adaptive radiations in bacterial species and the maintenance of diversity. Most of these studies are highly interdisciplinary in nature, and done in collaboration with mathematicians, statisticians, computer scientists, geologists, environmental engineers, physicians, and clinical scientists.

- Human Microbiome
The microbiota normally associated with the human body have an important influence on human development, physiology, immunity, and nutrition. The vast majority of these indigenous microbiota exists in a mutualistic relationship with their human host, while others are opportunistic pathogens that can cause both chronic infections and life-threatening diseases.
- Biodiversity and Biogeography
Recent advances in genomics and high throughput sequencing make it possible to characterize the extraordinary microbial diversity found on Earth in ways that were never before possible. The data obtained enables us to test hypotheses regarding patterns and processes in microbia communities, and to gauge responses to changing environmental conditions, perturbations, and treatments.
Mechanisms that lead to the genesis and maintenance of diversity in communities have intrigued both geneticists and ecologists alike for decades. This is particularly challenging in studies of microbial communities in which ecological and evolutionary processes occur on roughly the same timescale and where the outcome of these processes are affected by the spatial structure in which these communities grow.
