Exploiting Biology-Inspired Electrochemical Sensing to Study the Fate of Molecules in the Body

The ability to monitor arbitrary molecules in situ in the body as we undergo normal daily routines could empower us to make educated decisions regarding our diet, fitness, medical treatments and overall health status. Our laboratory pursues this vision by developing biology-inspired electrochemical sensors that support real-time, continuous measurements of a wide range of physiologically-important molecules in vivo. Our research blends chemistry with engineering, biophysics and pharmacology to, for example, study factors involved in the recognition of small-molecule targets by nucleic acid- or peptide-based receptors, develop metabolism-responsive drug delivery approaches, and produce diagnostic platforms for personalized health care. We pursue these goals in an environment that nurtures creativity, inclusivity of ideas, and innovation.
