Research collaboration: Cross-disciplinary training in sustainable chemistry and chemical processes Greg M. Swain, Professor of Chemistry in the Department of Chemistry at Michigan State University, is researching cross-disciplinary training in sustainable chemistry and chemical processes. Here, he emphasizes the importance of teamwork for effective research collaborations. The Research Experiences for Undergraduates (REU) program in the Department of Chemistry at Michigan State University aims to educate students majoring in chemistry, biochemistry, and chemical engineering about significant societal sustainability challenges. The program provides graduate-level interdisciplinary research experiences that address various aspects of these challenges.
