Dr. Hall helped launch and build the SciTS field through her leadership conducting empirical studies, developing conceptual frameworks, creating practical strategies and resources as well as activities such as editing special journal issues, chairing the Annual SciTS Conferences (2013-2017). Her work aims to build an evidence base for effective team science approaches and support the translation of emerging knowledge into policies and practices. She regularly delivers keynotes to stakeholders throughout the scientific enterprise, including forums for government representatives, scientists, and university administrators and regularly serves on advisory committees of large complex research initiatives and for funding organizations and federal agencies (e.g., USAF, PCORI, NSF, ARO, OSTP). Notably, she served as a member of The National Academies Committee on the Science of Team Science (2012-15), which produced the report Enhancing the Effectiveness of Team Science (listed in the top 25 most downloaded National Academies Press reports out of the more than 9000 released online since 1994). While at NCI, Dr. Hall has helped advance research areas such as dissemination and implementation science, system science approaches, teams/groups in health and healthcare and promote the use, testing, and development of health behavior theory in cancer prevention and control research. Prior to arriving at NCI, Dr. Hall's program of research included the development of behavioral science methodologies such as the design of survey protocols, meta-analytic techniques for health behavior theory testing, as well as on applications of health behavior theory to multiple content areas and the development of interventions to foster health promotion and disease prevention behaviors. Dr. Hall earned her PhD at the University of Rhode Island (URI) in Psychology with specializations in clinical psychology, neuropsychology, and behavioral science.
