David earned his Ph.D. at Georgia Institute of Technology, performing research both as a synthetic and analytical chemist and then added molecular and structural biology expertise as a postdoctoral fellow. After several years working in small technology-based companies, he returned to Georgia Tech to join the Fernández group to advance metabolomics and lipidomics research efforts. He is currently a senior research scientist in the lab, investigating metabolomic profiling of biological systems to understand system perturbation, for example, from exercise, injury, disease, or therapeutic administration. As part of the NIH funded Molecular Transducers of Physical Activity Consortium (MoTrPAC), he leads the global lipidomic assays at the Georgia Tech chemical analysis site. One goal of the consortium is to establish a molecular basis for the benefits of exercise. Since 2015, David directs the metabolomic/lipidomic and small molecular analysis services in the Systems Mass Spectrometry Core (SyMS-C) at Georgia Tech.
