Children’s Medical Center Research Institute at UT Southwestern (CRI)
Children’s Medical Center Research Institute at UT Southwestern (CRI) was established in 2011 as a joint venture designed to combine Children’s Health’s comprehensive clinical expertise and the internationally recognized scientific environment of UT Southwestern Medical Center.
Located in the heart of Dallas’ Southwestern Medical District, CRI represents an unprecedented opportunity for interdisciplinary groups of high-caliber scientists and physicians to pursue research at the interface of stem cell biology, cancer and metabolism. Together, these fields hold unusual potential for discoveries that can yield groundbreaking advances in science and medicine and further drive CRI’s mission — curing someone who otherwise would not be cured.
Celebrating 10 Years of CRI
Join us on the road to discovery
Ever since Hippocrates first investigated the causes of sickness, an understanding of basic science has been humankind’s only hope to overcome disease. However, discoveries that lead to medical breakthroughs do not come easily. Hard work, determination and sustained resources are necessary to bring scientific findings from the bench to the bedside and yield new strategies for treating disease.
To invest in research is to invest in the future. Research discoveries at CRI chart new pathways for understanding and treating disease, helping to transform medical outcomes for all patients, big and small.
Several early, generous donations helped CRI create a solid foundation for growth. Initial major funding came in 2012 when the Hamon Charitable Foundation donated $10 million in the second-largest gift ever made to Children’s Health at the time. Also in 2012, Children’s Health honored Ric and Debbie Scripps for their volunteerism, leadership and philanthropy through the establishment of the Scripps Society. The Scripps Society recognizes friends of CRI who have made contributions of $1 million or more and embody the Children’s Medical Center mission — to make life better for children.
