Saumya Sinha

Hello! I am a Postdoctoral Researcher at the National Laboratory of the Rockies (formerly named NREL) in Boulder, Colorado. My research lies at the intersection of advanced Machine Learning (ML) and the physical sciences, specifically within the domain of Scientific Machine Learning (SciML). I completed my Ph.D. in Computer Science at the University of Colorado Boulder in 2023, advised by Prof. Claire Monteleoni. My academic foundation was built at the Indian Institute of Technology (IIT) Kharagpur, where I earned my Integrated BS and MS in Mathematics and Computing.

At the lab, I am working in the Artificial Intelligence, Learning, and Intelligent Systems (ALIS) group, developing multimodal generative AI systems for building energy modeling and investigating LLMs to enhance scientific reasoning.

Previously, I have worked on modelling environmental impacts:

Sea-level Predictions: Building ML frameworks to fuse climate model simulations with satellite altimetry for future sea-level rise projections.
Renewable Energy Forecasting: Developing deep sequence learning architectures for probabilistic solar irradiance forecasting.
Extreme Event Detection: Using unsupervised deep learning to detect anomalies like avalanches from satellite imagery. (Spotlight talk at a NeurIPS workshop: link)

My long-term research goal is to develop physics-informed and interpretable AI systems that enhance scientific reasoning and transparency in high-stakes scientific applications.

Outside of research, I love to cook, watch tennis, and bike, and I am enjoying my time in Boulder!
