Dr. Anderson is honored for developing novel improvements to the technique of hydrogen-deuterium mass spectrometry (HDX-MS) that facilitate studies of the complex folding and motion of proteins that make up many new pharmaceuticals. Dr. Anderson's method for removing interfering sample components enables automated analysis of a class of molecules that could not be measured previously by HDX-MS, and he was key to the development of a reduced-temperature system that achieves unprecedented measurement accuracy, thereby providing industry with tools for creating new and effective drugs.
