We study the physiological state of colonized bacteria in the mammalian large intestine. With NIH funding we characterize the symbiotic relationship between E. coli and anaerobes that degrade complex polysaccharides, which in turn release simple sugars to cross-feed E. coli. In addition, we develop intuitive displays and computational environments for functional genomics data analysis. Our E. coli Gene Expression Database serves as a community resource.

Burnap 
We research the oxygenic photosynthetic mechanism in cyanobacteria. We have projects looking into the catalytic capabilities of specific photosynthetic enzymes and projects examining the adaptive mechanisms that enable cyanobacteria to thrive and survive diverse environments. The projects address basic scientific questions as well as applied questions relevant to solar energy, green chemical production, and CO2 mitigation. Hypotheses are addressed using advanced molecular genetic and bioinformatic tools to reprogram the DNA sequences encoding specific molecules and pathways. To evaluate the hypothesized changes due to the genetic reprograming, we utilize a variety of biochemical and biophysical to probe the targeted molecules and pathways.

Epithelia of the skin, and mucous membranes (of the respiratory, gastrointestinal and genitourinary tracts) are especially susceptible to infection. Upon infection, specialized leukocytes within the epithelia, termed dendritic cells, take in and carry foreign substances from these tissues to lymphoid tissues in order to stimulate immune responses that fight infection. We study proteins that modulate the capacity of these cells to stimulate immune responses following their arrival in lymphoid tissues.

We are an environmental microbiology group with broad research interests. We are active on multiple research fronts, spanning all three domains of life. Currently, our work is focused on two main research areas: Environmental genomics of novel yet-uncultured microbial phyla, and diversity, metabolism, genomics, and biotechnological potential of the anaerobic gut fungi. Please visit the research section for additional details.

Fathepure 
Research in Babu Fathepure’ s lab focuses on aerobic and anaerobic biodegradation petroleum hydrocarbons in hypersaline environments. We use genome-based tools to characterize hydrocarbon degrading microbial communities and their metabolic capacity. We seek to isolate novel hydrocarbon degrading bacteria and archaea and study their ecology, physiology and molecular mechanisms of hydrocarbon degradation at elevated salinity. Also, our lab explores degradation of plant lignin using bacteria and fungi for enhanced saccharification and efficient biofuel production. We use genomic and proteomic approach to understand lignin-active genes and proteins (enzymes) involved in the delignification of plant biomass.

Hadwiger 
Eukaryotic cells respond to a wide variety of external signals that can regulate cellular growth, division, differentiation, migration, and function. Many of these signals are detected by G protein coupled receptors stimulate specific cell responses. The goals of Dr. Hadwiger's research program are to identify the molecular components of G protein mediated signal transduction pathways and to elucidate how these components act together to transmit signals important for developmental processes such as cellular migration and differentiation. Dr. Hadwiger's laboratory has investigated signaling pathways that regulate the foraging and development of Dictyostelium. This model organism provides an excellent system for the genetic and biochemical characterization of cell movement, cell differentiation, and cell-cell signaling. The research in Dr. Hadwiger's lab has provided insight into proteins and mechanisms that are important for signal transduction pathway specificity.

We use photoreceptor proteins as model systems for studying protein folding, function, and signaling, and have started to explore biotechnological applications for these proteins. Our long-term goal is to uncover fundamental principles in these processes, and to develop biosensors with useful applications. In addition, we are developing novel highly sensitive, specific, and fast biodetection devices based on engineered proteins that allow a direct optical readout.

My broad research interest is to study the structure and function of azoreductase, an oxidoreductase, in Enterococus faecium, Clostridium perfringens, and Pseudomonas aeruginosa. These bacteria are potential pathogens in humans. We have rescued the genes and characterized the proteins for azoreductase and quinone reductase activity. This multi-functional role may provide a mechanism for bacterial survival and pathogenicity. Techniques used in our studies include molecular biology, enzyme kinetics, computer modeling, and X-ray crystallography.

Our lab is interested in understanding the molecular mechanisms of calcium (Ca2+) signaling in bacterial physiology. Since Ca2+ regulates essential processes in eukaryotes, even slight abnormalities in cellular Ca2+ homeostasis are associated with many human diseases, including those caused by bacterial infections. We aim to characterize Ca2+ signal transduction cascades regulating virulence in Pseudomonas aeruginosa, a human pathogen causing severe chronic infections.

My scientific interest emphasizes biological views of how and why simple eukaryotes decide to convert one functional molecule into another. Currently we are involved in a metaproteogenomic effort to determine biomass degrading enzymes which function at extreme high temperatures (95 0C). These enzymes are useful to further engineer crop plants (corn) the biomass source for biofuel production.

My lab is interested in the molecular interactions between obligate-intracellular bacterial pathogens and their eukaryotic host-cell. I have worked with Rickettsiae, Chlamydiae, and Coxiellae species during my career.Our current research is focused on the obligate-intracellular bacteria, Coxiella burnetii. C. burnetii is the etiologic agent of Q fever and chronic diseases such as endocarditis, hepatitis, and chronic fatigue.

Our lab is interested in exploring the metabolic diversities in single cell genomes of not-yet cultured Bacteria and Archaea. We analyze single-amplified-genomes (SAGs) of candidate phyla including the candidate bacterial phyla WS3 "Latescibacteria," and WWE1 "Cloacimonetes," and the candidate archaeal superphylum DPANN. We are also interested in studying the evolutionary history of the Neocallimastigomycota, the fungal phylum of the anaerobic gut fungi (AGF). Currently, we are conducting a pan genomic survey of all 6 known AGF genera, and utilizing the data for an extensive phylogenomic analysis of this phylum, especially for resolving the evolutionary history of Neocallimastigomycota within the fungal tree of life.
