We are working to develop the first additive manufacturing (AM) technique that utilizes photopolymerization to produce high-resolution objects made of recyclable thermoplastics. Currently, AM techniques for recyclable thermoplastic polymers rely on local heating to melt and reshape the material. Other AM methods use photopolymerization, which can produce parts with superior surface finish and detail. In these methods, the polymer solid polymer forms within a bath containing the monomer. These methods rely on an intrinsic crosslinking mechanism in thermoset polymers-- therefore the intricate detail and quality achieved in the output products come at the expense of compatibility with large-scale recycling processes.

Wind energy is a fast-growing source of renewable energy; however, it is also a fast-growing source of solid waste. While the concrete and steel bases are long-lived, the wind turbine blades are typically replaced every 20-25 years. This project aims to establish realistic end-of-life options for materials from wind turbine blades by examining processing options and identifying re-use pathways with mitigated environmental impact and high likelihood of adoption.

Mosquitos are more than a nuisance: they are one of the most dangerous animals to human health. Every year, there are hundreds of millions of cases of mosquito born disease (e.g. malaria, dengue, Zika, yellow fever) that overwhelm healthcare systems across the world, and the effects of climate change are exacerbating the spread. Therefore, there is a need to find higher-performing solutions to decrease vector and host contact and effectively stem the spread of these diseases.
