My research interests at NIST have centered on modification of surfaces for optimization of biosensors, protein arrays, protein structure-function studies, and ultrathin film metrology. Currently, much of my work is directed toward the synthesis of lipidic anchor molecules that form the basis of tethered bilayer lipid membranes (tBLMs) for the study of integral membrane proteins (IMPs). The lipidic tether compounds contain an oligo(ethylene oxide) [OEO] motif to provide a flexible, polar segment capable of supporting an aqueous submembrane reservoir of the tBLM, a condition necessary for optimal IMP functional reconstitution. The tBLMs enable a wide range of metrology, including neutron scattering techniques, to further probe IMP structure and function. Other work has focused on understanding the control of protein adsorption. We have shown that, for the OEO motif, loosely packed, conformationally mobile, uniformly-distributed, surface-bound molecules are the necessary and sufficient conditions for inhibition of nonspecific protein adsorption. Synthetic targets are those in which the optimal spacing between OEO segments and lateral stabilization interactions result directly from the molecular structure.

Originally from Iowa, I am married with three kids (all grown now) and assorted pets. Although replaced hips have stopped my (previous) sport interests (handball, running, hiking, skiing), I am a strong advocate of fitness through exercise and nutrition. I teach a cycle class.
