Quantifying Uncertainty in Complex Physical Systems: Application to Energy Conversion and Environmen
In search of better-burning fuels, or more accurate projections of climate change, researchers inevitably work through multiple models, sometimes at great cost. Youssef Marzouk hopes to provide energy and environmental scientists constructive and efficient new approaches to modeling complex engineered systems.
