Fraser

Research in the Fraser Lab is concerned with materials chemistry—synthesis, properties, and applications, along with environmental, health and societal impacts. While developing routes to polymeric metal complexes—well-defined hybrid inorganic-organic materials inspired by metalloproteins, combining coordination chemistry and controlled polymerization—we made two important discoveries involving luminescent boron complexes.  Difluoroboron β-diketonate dyes show intense fluorescence, 2-photon absorption, and environment sensitive emission.

DuBay

The design of self-assembling nanomaterials stands as one of the great challenges in modern molecular science. The DuBay group employs theoretical and computational tools to address this challenge through investigations that lie at the intersection of soft condensed matter physics, polymer chemistry, biophysics, and nanomaterials.

Membrane proteins facilitate the transfer of information across lipid bilayers, comprise approximately 25% of a typical proteome, and represent over half of all drug targets. The membrane proteins that mediate interactions between bacterial pathogens and hosts are of particular interest to our laboratory. Invasive bacterial pathogens are responsible for many lethal diseases and epidemics, including plague and meningitis. Although these bacteria have diverse mechanisms of cellular invasion, all of the pathways rely upon interactions between host and bacterial membrane proteins.

Membrane Proteins and Cell Signaling

Membranes and membrane proteins participate in some of the most important and interesting cellular processes. Energy transduction, cell signaling, membrane excitability, secretion and immune recognition are examples of a few of the processes mediated by membrane proteins. However, the molecular mechanisms by which lipids and membrane proteins accomplish these tasks are largely unknown. We primarily use  EPR spectroscopy and high-resolution NMR to investigate the structure and function of membrane proteins.

Our lab is fundamentally interested in understanding, from a structural and biophysical perspective, the functioning of proteins involved in regulating transcription, particularly those involved in the dysregulation associated with the development of cancer. Structural and functional characterization of the native forms of these proteins and their relevant complexes via NMR spectroscopy, X-ray crystallography, and a variety of other techniques provides a baseline of understanding.
