Team Science Toolkit is an interactive website to help support, conduct, and study team-based research. Interdisciplinary, transdisciplinary, or cross-disciplinary research is becoming more and more important to scientific breakthroughs and progress. But doing this kind of work can be challenging because of different disciplinary values, cultures, and communications and researchers are typically trained within a single discipline. This is a great resource for researchers or faculty planning research projects that include multiple disciplines, facing challenges, or needing ideas. Despite being housed in the National Cancer Institute, it is relevant for researchers from a wide variety of disciplines.
