I am currently a Principal Consultant in the Sustainability Consulting group at Sphera. I have been actively working in the areas of environmental systems analysis and decision support, life-cycle assessment, optimization, and sustainable materials management since 2006. I have published over thirty peer-reviewed journal articles in these research areas. I work on diverse research and consulting projects for domestic and international government agencies, industry, and non-governmental organizations. I co-authored two of the three best environmental policy analysis papers in Environmental Science & Technology in 2019.
