Our Team

Research teams at the Center for Outcomes Research (COR) conduct applied research, lead innovation in research design, promote capacity to conduct health outcomes research, and provide national and international leadership in transformations in healthcare delivery and improvements in patient outcomes. In 2019 alone, COR scientists published over 50 papers in leading peer-reviewed journals and were invited by the Centers for Medicare and Medicaid Services (CMS), U.S. Congress, and the United Nation’s International Atomic Energy Agency (IAEA) as experts on topics such as sepsis recognition and response, the state of telemedicine, and public health research methodology. The COR is uniquely positioned to draw support and direction from the rich clinical environment that characterizes Houston Methodist and to engage multi-disciplinary research faculty and students from Texas A&M University in the fields of health services research, health policy and economics, health systems engineering, architecture, computer science, public health, and architecture. Our interdisciplinary research portfolio focuses on improving the outcomes for patients treated in acute-care settings and throughout the cycle of their care to the ambulatory setting and their communities.
