Position description
Dr. Boya Xiong at the University of Minnesota, Twin Cities seeks 1 postdoc and 1 PhD student to study nanoplastic generation and release using advanced atomic force microscopy (AFM) tools. This work will be supported through the NSF CAREER award. The project leverages the novel single-asperity nanoscratch method and other advanced AFM modes to visualize the mechanism of nanoplastic release and to identify unique nanoscale properties that result in health impacts. Outcomes will include how abrasion conditions, plastic properties, and UV-exposure shape release profile, enabling risk assessment and screening tools for future polymers.
Anticipated start: Flexible, preferably before Jan 2026. For PhD, Fall 2026 will be considered.
