Dr. Buddhika Hapuwatte is a researcher working with the Information Modeling and Testing Group in the Systems Integration Division at NIST. His research focus includes modeling product life cycles, system optimization in the circular economy, and quantifying greenhouse gas avoidance through industrial material repurposing.
During his Ph.D., Dr. Hapuwatte conducted research on advancing the circular economy by optimizing the design and production planning of sustainable multi-generation products. His work involved developing sustainability metrics, introducing the dynamic sustainability evaluation of productions, and integrating market diffusion models to forecast a product’s sustainability performance over time. Additionally, he has a keen interest in Lean system application to continuously improve production systems and complement sustainable manufacturing.
Over the years, Dr. Hapuwatte has published his work on the above-mentioned research areas in a number of high-impact journals and international conferences.
