Through various roles with increasing responsibilities, I engaged in discovery and development of small molecule pharmaceuticals from natural sources while applying or evolving my experience in the following areas: • managing small groups • working with multi-disciplinary teams • conduction natural product analysis and identification by applying nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry (MS). Significant contributions were made to strategic initiatives for improving Natural Product drug-discovery workflow, resulting in accelerated identification of novel natural products.
