Our laboratory believes that the progress in science can be made through better measurement techniques. To that end, we are developing novel microfluidic, electrophoretic, electrochemical, and mass spectrometric techniques that can be used for a variety of problems in chemical biology. We are using droplet microfluidics interfaced to mass spectrometry to enable high-throughput screening at the nanoliter scale without requiring labels. This technology can be used to screen for drugs and chemical probes of enzymes and protein-protein interactions. We are presently screening for modulators of sirtuins and chaperone proteins. This technology can also be used to evolve enzymes for specific reactions. Another thrust of the group has been to develop new ways to measure neurochemicals in vivo. This allows the concentration dynamics of neurotransmitters to be correlated to behavior, drugs, and pathophysiology, e.g. Parkinson's Disease. We have developed microfluidic and LC-MS methods for these measurements. A third thrust of the group is to better understand insulin and glucagon secretion and how they are disrupted in type 2 diabetes. We are using LC-MS based metabolomics and sensors to measure release at single cells to study hormone secretion.
