Amritanshu develop computational methods and models for electrical energy systems with a real-world impact. His focus areas are sustainable smart cities, renewable integration, electric mobility, grid reliability and resilience, cybersecurity, and energy equity. In the past, Amritanshu (with his colleagues) developed a novel circuit-theoretic simulation and optimization framework for power grids. The project culminated in a new grid analytics tool: Simulation of Unified Grid Analysis and Renewables (SUGAR), which has since been commercialized at Pearl Street Technologies, Inc.
