Brady

Riesgraf

Clinical Associate

Brady Riesgraf graduated from the University of Notre Dame’s Engineering, Science, and Technology Entrepreneurial Masters (ESTEEM) program, after receiving his undergraduate degree in neurobiology. Brady’s graduate capstone thesis focused on medical device analysis—specifically, the study of neuromodulator spinal implants for the Feinstein Institute for Medical Research (FMIR) and their Center for Bioelectronic Medicine. Prior to attending to Notre Dame, he also worked with Mayo Clinic Ventures, integrating his background in clinical and biological research to enhance patient care through device development within the departments of pediatrics and neurology.

Following acceptance to medical school, Brady decided to pivot to the commercial sector, spending 18 months overseeing an innovation group with Booz Allen Hamilton before returning to medicine and joining the BalancedBack team.

In his role as a clinical associate, Brady touches on multiple parts of the BalancedBack operation, primarily focusing his efforts on patient qualification, as well as business development, data collection, and clinical trial refinement. In the latter, Brady’s experience with Mayo Clinic and FMIR will be especially important as we leverage his expertise with trials and grant writing for device approvals.
