Heather Liddell is an Assistant Professor at Purdue University in West Lafayette, Indiana, USA. Her research group applies interdisciplinary engineering approaches to address multiscale research challenges in manufacturing sustainability, including an emphasis on input-output approaches.

Details

Heather Liddell is an Assistant Professor at Purdue University with joint appointments in Mechanical Engineering and Sustainability Engineering & Environmental Engineering. She studies resource use and environmental impacts in manufacturing, focusing on technical strategies for improving the sustainability of the industrial sector. Her research integrates top-down strategies (e.g., supply chain modeling) and bottom-up strategies (e.g., impact assessments at the product or process level). Prior to joining Purdue, Dr. Liddell was a senior scientist and group leader at Energetics, where she worked closely with the U.S. Department of Energy to develop strategies for resource-efficient and decarbonized manufacturing in the United States. Dr. Liddell holds BS and MS degrees in mechanical engineering and a PhD in materials science from the University of Rochester. She completed postdoctoral training at the U.S. Naval Research Laboratory.

Research Interests

industrial decarbonization strategies; country-level energy modeling for U.S. production systems; environmentally extended input-output modeling; life cycle assessment for early-stage manufacturing technologies; automated life cycle assessment; sustainable supply chains and circularity
