Two Regenstrief Institute research scientists were invited to present their work at nationally recognized grand rounds events, highlighting the Institute’s leadership in public health informatics and geriatric research.

Mayo Clinic
On October 13, 2025, Regenstrief’s Director of the Center for Biomedical Informatics, Brian E. Dixon, MPA, PhD, delivered an invited talk at the Mayo Clinic Clinical Informatics Grand Rounds.

His presentation, “Modernizing Public Health Information Systems: Progress, Challenges, and Future Directions,” brought together Mayo faculty, clinicians, residents and PhD students.

Dr. Dixon, a professor of biomedical informatics at the Indiana University Fairbanks School of Public Health, highlighted:

  • Regenstrief’s public health informatics research and programmatic work.
  • progress of the CDC Public Health Data Modernization Initiative.
  • how Regenstrief’s projects align with CDC goals to strengthen U.S. public health data systems.

IMPACT Collaboratory
On October 16, 2025, Regenstrief Research Scientist Kathleen Unroe, M.D., MHA, presented “Building the NEXT STEPs Network” as part of the IMPACT Collaboratory Grand Rounds, a national webinar series focused on embedded pragmatic clinical trials among people living with dementia and their care partners.

Dr. Unroe, a geriatrician and nursing home physician, leads NEXT STEPs, an NIA-funded U24 program designed to advance clinical trials in nursing home settings. Her presentation highlighted the initiative’s role in strengthening infrastructure, improving trial readiness, and accelerating research in long-term care.

Regenstrief Institute researchers continue to be recognized nationally for advancing data-driven public health solutions, improving care delivery for older adults, and leading innovative clinical trials across health systems.
