Students and Faculty Present at the EPA National Student Design Expo

Josh Sedarski (‘24, Physics), Maddie Sowinski (‘23, Applied Physics), and Dr. Lifeng Dong will present their project, “Increased Sensitivity for Lead Detection in Drinking Water Using Surface Enhanced Raman Spectroscopy,” at the virtual National Student Design Expo on June 21 to 25, 2021. Last year, 32 innovative technology projects were awarded grants to design “solutions for a sustainable future” by the US Environmental Protection Agency (EPA) through the People, Prosperity, and the Planet (P3) national competition.

Lead contamination in drinking water poses a serious health risk for communities across the United States, especially for children. As such, affordable, ultrasensitive detection at miniscule levels of contamination is crucial to maintain healthy and safe communities. The Hamline student team is developing an affordable and sensitive Raman spectroscopy-based method of lead detection that will be accessible and easy to use in a range of communities.

For each project, viewers will have access to a brief video summary, as well as their poster and a short written description. Upon making a free account on the National Student Design Expo website, audience members will be able to leave questions or comments they may have about the research.
