Heriati Sitosari Named Recipient of the 2025 IADR John Greenspan Travel Award

Published on: June 4, 2025

Alexandria, VA, USA – The International Association for Dental, Oral, and Craniofacial Research (IADR) has announced Heriati Sitosari as the 2025 recipient of the IADR John Greenspan Travel Award. Sitosari, from Universitas Gadjah Mada, Yogyakarta, Indonesia, was recognized during the Opening Ceremonies of the 103rd General Session of the IADR, which was held in conjunction with the IADR/Pan European Regional Congress on June 25-28, 2025 in Barcelona, Spain.

Sitosari, a current member of the IADR Mineralized Tissue Group, will travel to the General Session to present the abstract, "Role of O-GlcNAc Transferase in Extracellular Vesicle-Mediated Osteoblast Differentiation." This study explores the role of OGT in regulating EVs and how these vesicles influence osteoblast differentiation. Its results provide novel insights into the regulatory mechanisms of OGT in bone formation, and demonstrate that OGT plays a critical role in EV-mediated osteoblast differentiation by modulating calcium levels within EVs.

Funded by generous contributions from IADR donors, the IADR John Greenspan Travel Award is given annually in the amount of $2,000 to new investigators residing in low to middle-income countries to attend and present their research at the IADR General Session. IADR members who are new investigators within 10 years of completing their last terminal degree (Ph.D., D.D.S., D.M.D., or equivalent) at the time of the submission deadline are eligible to apply for the award when submitting an abstract for an IADR General Session. The award is in memory of John Greenspan, a past president of IADR with a distinguished five-decade career in oral pathology, oral medicine, and global oral health initiatives.
