Ambarish Nag is a senior data scientist in 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, photovoltaics (PV), and the electric grid. His recent transportation research projects include 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 worked with the team that developed the RdTools open-source library to support reproducible technical analysis of time-series data from PV energy systems. He also participated in the development of microservices for the DOE North American Energy Resilience Model. As a part of the Deep Green Project funded by DOE's Biological and Environmental Research program, Ambarish contributed to the bioinformatics analysis and de novo structure predictions of conserved unannotated green lineage proteins. In addition, he developed data management software infrastructure for the Center for Bioenergy Innovation, one of the four Biological and Environmental Research Centers within the DOE’s Office of Science. So far, he has made significant contributions to the bioinformatics and computational biology research at NREL.
