Scott Anthony Robson
Structural Biologist / NMR Spectroscopist
I am a research scientist in Gerhard Wagner's group at Harvard Medical School, where I study protein structure and function. Our group uses a number of biochemical and biophysical techniques, but principally we used Nuclear Magnetic Resonance (NMR) to study proteins. NMR is a powerful tool to observe protein structure, but is invaluable for studying protein dynamics and function at the atomic level. It is through these studies we are uncovering how protein-protein interactions, small molecule binding and enzymatic reactions are mediated by a protein's ability to flex and move.
I am primarily interested in understanding how proteins adopt multiple structural states while acting as enzymes and transporters in pathogenic bacterial systems. While NMR is a powerful technique, it is often limited in the types of systems were it can be applied successfully. Part of my research efforts focus on circumventing these limitations by using advanced data acquisition techniques and novel chemical labeling schemes.
