Ambarish Nag is a senior data scientist in the Data, Analysis, and Visualization Group at the Computational Science Center. He joined NREL as a postdoctoral researcher in 2009.  His current interests involve the application of data science and machine learning to multiple aspects of renewable energy research with emphasis on bioenergy, transportation, and photovoltaics. His recent transportation research projects have included data analytics for the development of a digital twin of the Chattanooga, Tennessee, traffic system as part of the U.S. Department of Energy (DOE) Vehicle Technologies Office-funded Regional Mobility project and the creation of an R-Shiny prototype application for customization and visualization of the MEP (Mobility-Energy-Productivity) metric as part of a collaboration between NREL and the Ford Motor Company. Ambarish has been actively involved in the bioinformatics and computational biology research at NREL. He is a co-principal investigator for DOE's Biological and Environmental Research program's Deep Green Project, and as part of this project, he has contributed to the bioinformatics analysis and de novo structure predictions of conserved unannotated green lineage proteins.
