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.

Join us on the road to relentless 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.

The Research Team

The CRI is led by Dr. Sean Morrison, an internationally recognized stem-cell expert who is a Howard Hughes Medical Institute Investigator and a member of the National Academy of Medicine, the National Academy of Sciences, and the European Molecular Biology Organization. Dr. Morrison has already recruited more than 150 researchers and scientific staff, who are now laying the groundwork for future research breakthroughs. Children’s Medical Center Foundation aspires to build on this potential and raise more than $200 million to help CRI grow to 200 scientists working in 15 labs.
Sean J. Morrison, Ph.D.
Director of CRI

Dr. Morrison is the director of CRI and a Howard Hughes Medical Institute Investigator. He is also a member of the National Academy of Medicine, National Academy of Sciences, and the European Molecular Biology Organization. He holds the Mary McDermott Cook Chair in Pediatric Genetics and the Kathryne and Gene Bishop Distinguished Chair in Pediatric Research. Dr. Morrison completed his Ph.D. in immunology at Stanford University (1996) and a postdoctoral fellowship in neurobiology at Caltech (1999). From 1999 to 2011, Dr. Morrison was a professor at the University of Michigan, where he directed their Center for Stem Cell Biology. Dr. Morrison was among the first established investigators to be recruited to Texas as a Cancer Prevention and Research Institute of Texas (CPRIT) Scholar in Cancer Research. In December 2024, Dr. Morrison was honored with the American Society of Hematology’s E. Donnall Thomas Lecture and Prize for his paradigm-shifting research that has evolved how hematologists and other understand the regulation of hematopoietic stem cell function.
The Morrison Lab studies mechanisms that regulate stem cell function in adult tissues and the ways in which cancer cells hijack those mechanisms to enable the formation and spread of cancer.

The DeBerardinis Lab is working to understand how altered metabolism at the cellular level contributes to several serious diseases, including inborn errors of metabolism (the result of inherited genetic defects in metabolic enzymes that lead to chemical imbalances in children) and cancer.
Hao Zhu, M.D.
Professor and the Nancy B. and Jake L. Hamon Distinguished Chair in Therapeutic Oncology Research

Dr. Zhu is a professor in CRI and of pediatrics and internal medicine at UT Southwestern. He earned an M.D. from Harvard Medical School and performed research training at MIT. He trained in internal medicine at the University of California, San Francisco, and in medical oncology at the Dana-Farber Cancer Institute and Harvard. From 2008 to 2012, Dr. Zhu performed postdoctoral research at Boston Children’s Hospital, exploring connections between microRNAs, metabolism and regeneration in mouse models. In 2012, he was recruited to CRI as a CPRIT Scholar in Cancer Research. Researchers in his lab seek to determine the genetic and cellular factors that influence liver regeneration and cancer and to determine if these factors are common to both processes. They also are trying to identify protective mechanisms that might suppress cancer formation in the liver.
Prashant Mishra, M.D., Ph.D.
Associate Professor

Dr. Mishra is an associate professor in CRI and of pediatrics at UT Southwestern. He is also affiliated with the Cecil H. and Ida Green Comprehensive Center for Molecular, Computational, and Systems Biology. He earned both his M.D. and his Ph.D. from UT Southwestern’s Medical Scientist Training Program. He conducted his postdoctoral research at the California Institute of Technology, where he focused on studying mechanisms that control mitochondrial behavior.

During his time in the Kaelin Lab, he studied how metabolic reprogramming occurs in glioma and developed new strategies for brain-tumor therapy.
Dr. McBrayer’s lab is working to discover metabolic mechanisms that promote brain-tumor development and developing strategies to exploit altered metabolism for cancer therapy.
Benjamin Ohlstein, M.D., Ph.D.
Associate Professor

Benjamin Ohlstein received his M.D. and Ph.D. degrees from UT Southwestern Medical Center in 2002. He completed a postdoctoral fellowship at the Carnegie Institution in Baltimore, Maryland, in Allan C. Spradling’s laboratory in 2007. During his time in the Spradling Lab, he demonstrated that the adult Drosophila midgut, like the adult human intestine, is maintained by multipotent stem cells. He also found the notch signaling pathway plays a crucial role in how stem cells give rise to enterocytes and enteroendocrine cells.
After his postdoctoral studies, Dr. Ohlstein joined Columbia University Medical Center, where he was an associate professor of genetics and development and a member of the Columbia Stem Cell Initiative. He is a Howard Hughes Medical Institute Faculty Scholar. In 2020, Dr. Ohlstein joined as an associate professor in CRI and of pediatrics at UT Southwestern.
The Ohlstein Lab is working to better understand the mechanisms that guide normal and abnormal tissue functions, particularly in gastrointestinal organs such as the small and large intestines and stomach, using the Drosophila intestine as a model. Ultimately, a better understanding of the biology of the Drosophila intestinal stem cells will help with diagnosis, treatment and cures of various conditions that affect the human gastrointestinal tract.
Sihan Wu, Ph.D.
Assistant Professor

Dr. Wu has an extensive background in cancer genetics and genomics. After graduating from Sun-Yat-sen University (SYSU), where he majored in biotechnology in the Life Science School, he obtained a Ph.D. at the Zhongshan School of Medicine at SYSU. His doctoral research focused on how genetic alterations contribute to brain tumor development. His research led to the discovery that dysregulation of non-coding microRNAs contributes to the development of glioblastoma. Dr. Wu completed postdoctoral research at the Ludwig Institute for Cancer Research at the University of California, San Diego, under Dr. Paul Mischel’s mentorship. There he studied the structure and function of extrachromosomal DNA (ecDNA) in cancer, uncovering its circular shape and the functional impact of its unique physical conformation. In 2021, Dr. Wu joined as an assistant professor in CRI and of pediatrics at UT Southwestern and is a CPRIT Scholar.
