We are developing new metrics and measurement methods to allow designers to assess and plan for the recoverability of these complex products. Additionally, this work focuses on the identification of information and data needs to provide decision-support to consumers and enable end-of-life stakeholders (recyclers, municipalities, waste managers, infrastructure providers) that improve the volume of valuable microelectronics to be recovered.

The methods developed in this work will be used to inform future product design and may be a basis for corporate or open standards. We will drive the state of the art forward with advanced techniques in life cycle assessment, simulation, and AI- and data-driven design. Results will include a suite of decision support tools (metrics, models, and published research) and new standards to improve recovery outcomes, thereby strengthening supply chain resiliency via new material sources, and enabling stakeholders to respond dynamically to material availability challenges in the future.

We seek experienced research candidates with a background in products design, micro and nano engineering, and/or supply-chain interoperability, and a Ph.D. (preferred), M.S. and/or related experience with a record of research in peer-reviewed publications. US citizenship needed.

Key responsibilities will include but are not limited to:
