Marie G. Gantz

Senior Fellow, Statistics

Education

PhD, Biostatistics, University of Kentucky

MS, Applied Statistics, George Mason University

BA, Rhetoric & Communications Studies, University of Virginia

Marie G. Gantz is an expert in statistics, focused on leading data coordinating centers (DCCs) for clinical studies. She is skilled in randomization schemes, power and sample size considerations, outcome selection, interim monitoring, and statistical analysis methods. She provides oversight for every aspect of DCC operations, including development of protocols, case report forms and manuals of operations, electronic data capture systems programming, study progress and safety reporting, quality assurance including centralized and on-site data monitoring, statistical analysis, dissemination of results, public data sharing, study drug and placebo manufacturing, biospecimen collection and transport, capitation payments to clinical sites, and logistics and communications coordination. She has expertise in a variety of statistical methods, including hierarchical models for multilevel and longitudinal data, and survival modeling.

Dr. Gantz joined RTI in 2004. Currently, she serves as Principal Investigator (PI) for the Data Coordinating Centers of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Pelvic Floor Disorders Network, and the National Institute of Diabetes and Digestive and Kidney Diseases-funded Fecal Incontinence Treatment multi-site clinical trial. She is PI of the Research Coordinating Center of the NIH Common Fund’s Nutrition for Precision Health (NPH) Consortium, the first large ancillary study to the All of Us Research Program. 

In these roles, she collaborates with clinical investigators to design, implement, analyze, and publish data from randomized clinical trials and observational studies across a variety of clinical conditions impacting neonates, children, and adults. Her experience includes studies of gut microbiota, metabolites, and fungi, as well as microbiota from urinary and vaginal specimens. She studies clinical conditions including pelvic organ prolapse, fecal incontinence, urinary incontinence, extremely premature birth, and Prader-Willi syndrome. In NPH, she is part of a collaboration to understand how different people respond to various foods and dietary patterns.


Get To Know Marie Gantz

Dr. Gantz resides in Asheville, NC with her husband Lance, daughter Delia, and son Afton. She shared her experience at her first job, what made her interested in statistics, and the best part about working at RTI. 

My first two jobs after undergrad were as a housekeeper at a guest ranch in Wyoming and an office manager for a small construction company in Albuquerque, New Mexico. Those were a fun couple of years that allowed me to figure out my next move.

After graduating with a B.A., I became interested in research broadly speaking. Recognizing that any type of research involves statistics, I decided I wanted to be someone who could apply and interpret them, so I studied statistics as a graduate student. Earning a degree in statistics as opposed to a specific research field has allowed me to be involved in a range of research projects.

As my research interest have evolved, being at RTI has allowed me to pursue opportunities that excite me. The Fellow Program is the ultimate example. In 2013, my then-infant son was diagnosed with Prader-Willi Syndrome (PWS), and today my Fellow Program work involves accelerating research in rare diseases, including PWS. As a Fellow and a mentor, I believe strongly that if people are supported in doing research that excites and motivates them, that is a win-win situation for the individual and RTI.

Outside the Office

Dr. Gantz did not study statistics until she was in graduate school. Surprisingly, she majored in rhetoric and communication and minored in studio art during her undergraduate time at the University of Virginia.

When she’s not at work, Dr. Gantz enjoys knitting, reading, hiking, biking, and camping with her family. She also has a pet Aussiedoodle named Inigo after a character in the Princess Bride.
