    Dr. Lindsay Renfro is an Associate Professor of Research at the University of Southern California and the Associate Group Statistician for Children's Oncology Group (COG). COG is the pediatric cooperative group member of the NIH/NCI's National Clinical Trials Network and the world's largest organization dedicated exclusively to pediatric cancer research. Within COG, Dr. Renfro is also a faculty statistician for the Renal Tumors Committee, where she leads the design and analysis of therapeutic and biology-driven clinical trials for Wilms Tumor and related projects in pediatric renal cancer. Her expertise and methodological interests also include novel trial designs (e.g., adaptive, Bayesian, biomarker-driven, and master protocols), evaluation and validation of surrogate endpoints in clinical trials, and construction, validation, and implementation of disease-specific prognostic calculators for clinical use and decision-making. Dr. Renfro also enjoys teaching statistics to non-statisticians, mentoring students, traveling, and enjoying the mountains and beaches of Southern California with her son, Will.
