The National Science Foundation (NSF) awarded a $477,340 Project Grant to Montana State University (MSU) for the three-year REU Site: Exploring the Limits of Life - Understanding Biofilms in Extreme Environments program (CFDA 47.041, Engineering). The program supports 10 undergraduate students per year to conduct research on biofilms in extreme environments under the guidance of faculty experts at MSU's Thermal Biology Institute and Center for Biofilm Engineering. Key activities include helping students understand and predict characteristics of extreme biofilms, examine biofilm activities in built environments, and screen for novel biofilm applications. Participants also engage in professional development, community building, and science communication activities. The award period runs from April 1, 2024 to March 31, 2027 and aims to increase participation of underrepresented students in STEM fields.
