Five Bemidji State University students participated in the 2025 Red River Valley American Chemical Society Research Symposium on Feb. 21-22.

Three students presented research posters at the event. Chloe Knott and Ridge Flatness showcased their work with Dr. Kate Peterson, while Derek Hoffman presented his research with Dr. Bob Quandt.

All three earned a Judges’ Choice Presentation Award. Hoffman also won a periodic table trivia contest.

“I’m so proud of Chloe and Ridge for their hard work on their research project, their growth and willingness to challenge themselves,” Peterson said. “At the conference, they gained valuable experience communicating their work, received feedback on their project and networked with regional scientists and graduate students. The experience was invaluable for their academic and professional development.”

Their wins were significant, as they competed against undergraduates, graduate students and postdoctoral researchers. Participants included students from the University of North Dakota, North Dakota State University, Minnesota State University Moorhead, Mayville State University and Concordia College.

Knott and Flatness are synthesizing and evaluating molecules that emit light after reacting with hydrogen sulfide. These fluorescent probes help measure hydrogen sulfide levels in cells, aiding biochemists in studying its biological roles in cellular functions.

Hoffman’s research uses high-level computer-aided calculations to map the energy path of oxygen atoms and propargyl amine as they transition from reactants to products. He focuses on the formation of the formyl radical, an important species in combustion and atmospheric chemistry. Insights from his work could lead to a better understanding of fundamental reaction mechanisms and improved pollution controls.

“He is a great student doing some very difficult research all while taking a full load of classes and pitching for the BSU baseball team,” Quandt said. “I don’t know how he finds the time to get all of his work done.”

Hoffman is conducting this complex research while taking a full course load and pitching for the BSU baseball team. Knott and Flatness are also varsity athletes, competing in track and football respectively.
