Nature exhibits dynamics that span extraordinary ranges of space and time. In some cases, these dynamical hierarchies are well separated, simplifying their understanding and description. But chemistry and biology are replete with examples of dynamically coupled scales. Electron- and proton-transfer reactions couple intrinsically quantum-mechanical and classical-mechanical motions. Molecular motors convert atomic-scale reactions into nano-scale motion and work. And signaling pathways use molecular recognition processes to regulate activities at the cellular level. Understanding processes that bridge dynamical hierarchies is a fascinating and ongoing challenge. Our research focuses on the development of new theoretical methods to simulate and understand complex dynamics in chemistry and biology.

The cell has an incredible aptitude to rapidly adapt to environmental changes by altering its shape, volume and internal composition. Factors that affect protein structure and interactions, including crowding, ionic strength, and quinary interactions can all change due to this adaptation. I take advantage of the cell’s remarkable plasticity, and use it as a tool to perturb and study the dynamics of its proteome.

Chemistry and physics share tremendous potential at the nanoscale. This is where chemistry excels and where physics predicts that many properties can be tuned.  For example, quantum states, charging, spin, phonons, and plasmons show dramatic effects at this scale.  Colloidal synthesis enables the construction of nanostructures by chemical precipitation.  Our research is therefore driven by physical concepts and enabled by synthesis.

Metabolomics: a tool for systems biology, disease diagnosis and drug discovery

Robert Powers

Professor of Chemistry

University of Nebraska - Lincoln

Nuclear Magnetic Resonance (NMR) spectroscopy has proven itself an extremely versatile tool for exploring a variety of biological problems. NMR has been successfully used to determine the structure of numerous biomolecules, investigate biomolecular interactions, screen for potential drugs, determine structures of drug-complexes, and more recently as an important tool of metabolomics and systems biology. Metabolomics is used to monitor in vivo drug activity and to analyze biofluids (blood, urine, etc.) for drug toxicity, disease biomarkers, and personalized medicine. As a result, NMR is widely used in the pharmaceutical industry to aid in drug discovery efforts. Our research interest is focused on the application and development of NMR methodologies to improve the success rate and efficiency of drug discovery. This effort includes the development of NMR- and MS-based methods for metabolomics; and the application of NMR and bioinformatics to understand the structure, function and evolution of novel proteins and their corresponding therapeutic utility in structure-based drug design programs.

Fine structure of fatty acids by gas phase mass spectrometry

Tom Brenna  tom brenna

Professor, Pediatrics

Dell Medical School

Research Web Page

Our research group is concerned with three areas, requirements for polyunsaturated fatty acids in the perinatal period, development of advanced analytical chemical instrumentation, particularly mass spectrometry, for biomedical applications, and development of high precision isotope ratio mass spectrometry for anti-doping applications. Our polyunsaturated fatty acid work focuses on factors that influence demand for omega-3 and omega-6 fatty acids, notably prematurity, and most of our studies are conducted in non-human primates. Our instrumentation work is aimed at development of high precision isotope ratio mass spectrometry for tracer applications and for detection of natural physiological isotopic fractionation.

Imaging Mass Spectrometry of Three-Dimensional Cell Cultures

Amanda B. Hummon amanda hummon

Associate Professor

University of Notre Dame

ORCID ID:  0000-0002-1969-9013

Research Web Page

The Hummon research group seamlessly combines analytical chemistry and the study of cancer biology to explore gene products deregulated in the development and progression of cancer. Cancer arises from insults to the genome. With genomic damage, the expression levels of genes are altered from their normal state. Changes in the genome, transcriptome and proteome are highly conserved among samples from adenomas to carcinomas to metastases. Because genetic changes are commonly repeated among cancer patients, a better understanding of which genes, transcripts, and proteins are affected could have broad health implications. Therefore, the best way to understand the molecular underpinnings of cancer is to dissect the deregulated pathways that are contributing to the cancer phenotype, identify the aberrantly expressed genes and their products, and decipher their effect on downstream targets. The Hummon Research Group develops methods to evaluate both the transcriptome and the proteome in cancer cells.
