Dr. Ashwin Singh Parihar, an assistant professor of radiology at Washington University School of Medicine’s Mallinckrodt Institute of Radiology (MIR), has been selected as the 2026 William W. Olmsted Fellow in Radiology Education Journalism.
The prestigious program, awarded by the Radiological Society of North America (RSNA), is highly competitive and designed to cultivate emerging leaders in radiologic scholarly communication and scientific publishing. The fellowship provides early-career radiologists and trainees with a mentored, immersive experience within RSNA’s publication and editorial activities.
Parihar, a member of MIR’s nuclear medicine clinical section, completed his foundational medical training in India. He earned his MBBS degree in 2014 from the Veer Chandra Singh Garhwali Government Medical Sciences and Research Institute in Uttarakhand, India.

He then completed a nuclear medicine residency in 2019 at the Postgraduate Institute of Medical Education and Research (PGIMER) in Chandigarh, India. After serving as a senior resident at PGIMER, he moved to the United States to complete a postdoctoral research fellowship and a nuclear medicine residency at MIR, where he also served as chief resident.
As part of the Olmsted Fellowship, Parihar will receive a $5,000 stipend and work directly with the RSNA editorial offices to tailor the experience to his specific areas of interest.
“I deeply value and appreciate the roles of scientific journals that ensure important research gets communicated clearly, rigorously and to the right audiences,” Parihar stated noting that the fellowship represents an opportunity to gain an in-depth and firsthand understanding of the full editorial process.

At MIR, Parihar’s research focuses on the use of functional imaging to improve disease characterization and patient outcomes, as well as identifying novel theranostic targets in radio theranostics.
Parihar already has an extensive background in medical journalism. He currently serves as an associate editor for the journal Radiology and previously held roles as a deputy editor and associate editor on the Radiology Trainee Editorial Board. His contributions earned him the journal’s Editor’s Recognition Award with Distinction in 2024, alongside Special Distinction honors in 2023 and 2025.
His leadership extends beyond academic writing. Parihar serves as co-chair of the Committee on Quality and Evidence for the Society of Nuclear Medicine and Molecular Imaging and sits as an at-large member on the board of directors for the American College of Nuclear Medicine.
