About Me

Daniel J. Vreeman, PT, DPT, MS, FACMI

Dr. Daniel Vreeman is the Regenstrief-McDonald Scholar in Data Standards at the Indiana University School of Medicine and Director, LOINC and Health Data Standards at the Regenstrief Institute, Inc. His work is focused on creating a global health ecosystem where data is available with open standards that unlock the potential for information systems and applications to improve health decision-making and care. He leads the development of LOINC, the international standard for identifying health measurements, observations, and documents that is used in 175 countries to make data more portable and understandable to different computer systems. Dr. Vreeman is the author of the book LOINC Essentials: A step-by-step guide for getting your local codes mapped to LOINC, and teaches biomedical informatics at Indiana University.


My Vision

A world where people experience optimal health catalyzed by a seamless network of health information systems.


I received a Bachelor of Arts in Biological Sciences from Cornell University, and a Doctor of Physical Therapy (DPT) from Duke University. I also completed a two year NLM-sponsored Medical Informatics Research Fellowship at the Regenstrief Institute, Inc, which is associated with the Indiana University School of Medicine. While an informatics fellow, I earned a MS in Clinical Research with an emphasis on medical informatics, through the NIH-funded Clinical Investigator Training Enhancement (CITE) program.

In 2005 I joined the faculty of Indiana University, first in the School of Health and Rehabilitation Sciences, and now in the School of Medicine. I was also appointed a Research Scientist at the Regenstrief Institute, Inc. in 2005.

Research Interests

Research is a major component of my role at IU and Regenstrief, where I have focused on improving healthcare through the use of information technology. In particular, I am interested in standardized clinical vocabularies to support electronic health information exchange. My primary role is leading development of the international standard, called LOINC, at Regenstrief.

Awards and Honors

In 2018, I was given the inaugural Technology and Innovation Award from the American Physical Therapy Association’s section HPA The Catalyst. In 2017, I was elected as a fellow to the American College of Medical Informatics, which is the honorary college of elected informatics fellows from around the world who have made significant and sustained contributions to the field of medical informatics and who have met rigorous scholarly scrutiny by their peers. In 2017 I was also awarded the Distinguished Alumni Award from Duke University Physical Therapy Alumni Association. The Indianapolis Business Journal selected me for the 2015 Forty Under 40 list. For three consecutive years, my manuscripts were selected as a finalist for the Distinguished Paper Award, an award that highlights the most notable and distinguished papers accepted to the AMIA Annual Symposium. My AMIA 2007 paper ‘A Rationale for Parsimonious Laboratory Term Mapping by Frequency’ won that award. I’ve also been selected as a Distinguished Paper Reviewer in 2013 and 2014. I was senior author on a paper about the urgent need for competencies in biomedical informatics within physical therapy education that was published in the Journal of Physical Therapy Education. This paper earned the 2010 Stanford Award from the Education Section of the American Physical Therapy Association (APTA), given to the paper with the most influential ideas for physical therapist education.

Teaching Experience

I enjoy teaching medical informatics at Regenstrief and IU. Previously I taught P645 Evidence-based Critical Inquiry II and co-instructed P513 – Functional Anatomy and Clinical Biomechanics.

Clinical Interests

I have worked as a generalist on the inpatient wards at two level I trauma center hospitals in Indianapolis.


I’ve been a long-time member of the American Physical Therapy Association where I’m active in the Sections of Health Policy and Administration, Education, and Research. From 2007 to 2013 I served as the President of the Technology Special Interest Group of the APTA HPA section. I’m also a member of the American Medical Informatics Association and the American College of Medical Informatics.

Presentations and Publications

I have presented my work at numerous local, regional, national, and international meetings in physical therapy and medical informatics. Visit my speaking page for more information about talks and presentations I’ve given and the bibliography section of this website for a current list of publications.

Business Adventures

Blue Sky Premise, LLC is the company my wife (the more lovely Dr. Vreeman) and I co-founded to support our commercial activities in health and healthcare IT. Blue Sky Premise is the publisher for my LOINC Essentials eBook.

Personal Interests

Outside of work I enjoy many other diverse activities. I am a creative at the core. I’m passionate about design, music, and technology. When I’m not traveling, I love playing bass guitar and getting my exercise on the basketball court. I’m beginning to explore photography, especially capturing special moments with my boys. Even with all these interests, my favorite activity is spending time with my wife Lorrie (also a physical therapist) and my three young boys.
