    Wan is an assistant professor of animal and dairy science at UW–Platteville. Her primary research interest is in the application of non-thermal technologies for enhanced food safety and quality to achieve sustainable manufacturing goals. In addition, her research focuses on the utilization of food by-products and wastes for production of value-added ingredients. Wan’s position is funded by the Dairy Innovation Hub.

    Cold plasma has shown promise in safely reducing bacteria, cleaning surfaces, treating water, and even boosting plant health. To build on this potential, the research team is investing in new tools to better control and scale up cold plasma treatments for real-world use. The project includes the installation of specialized equipment that can generate plasma consistently and treat larger samples with greater precision. A new system will also boost production of plasma-activated water (PAW), increasing output fivefold. This special type of water has the potential to safely disinfect produce, protect crops from disease, and treat contaminated water – all without using harsh chemicals.

    Together with monitoring tools that ensure the safety and consistency of the treatments, this new setup will position UW-Platteville students and researchers to test and develop cold plasma solutions that support a safer food system and a healthier environment.
