Biography

Reed Selwyn, PhD, DABR is a practicing, board-certified (ABR) diagnostic medical physicist, Medical Physics Section Chief, and Executive Vice Chair of the Department of Radiology at the University of New Mexico. He has served in leadership roles in the Society of Nuclear Medicine and Molecular Imaging and in the Navy. Dr. Selwyn is a retired Naval officer who started in the Naval Reactors program and was the Training Director for Naval Nuclear Power Training Command before transferring to the Radiation Health Program. While in the Navy, Dr. Selwyn developed and directed a translational imaging facility to study traumatic brain injury, deployed to Afghanistan to install multiple MRI scanners, and served as technical advisor to the DOD for the Fukushima nuclear accident. Dr. Selwyn has received approximately $9M in DOD and NIH funding and has served on study sections for NIH, Brain Canada, Lerch Rett Foundation, Los Alamos National Laboratory, and as a Network of Experts for the FDA. Since coming to UNM in 2014, Dr. Selwyn received $1.8M S10 NIH High-End Instrumentation grant and installed the first Bruker 7T PET/MRI system in the U.S., developed and launched a Human Imaging Research Core, initiated a Medical Physics Outreach Program to provide quality services to underserved communities throughout New Mexico, and was instrumental in launching our first theranostics treatment (LUTATHERA). Dr. Selwyn has a research interest in targeted radiomicrosphere therapy for liver cancer with PET-based dosimetry and in advanced PET/MRI neuroimaging techniques for mild traumatic brain injury (mTBI).

Personal Statement

My research is focused on developing novel radioactive microspheres for imaging and
treating liver cancer. I have a patent for a radioactive glass microsphere, and I am actively
developing new resin and glass microspheres with biomedical engineering. Equally
important is my research involving traumatic brain injury and developing a novel biomarker
for mild concussion injury. A pilot study with arena football players was recently completed,
and small brain changes were detected using PET/MRI. In addition, I recently received a
High-End Instrumentation Award (S10) from the National Institutes of Health (NIH) to install
a state-of-the-art 7T MRI for preclinical imaging of neurological disorders and cancer. This
was the first S10 award received at UNM. I recently installed a PET scanner in the MRI,
which is the first commercial preclinical simultaneous PET/MRI scanner in the U.S. Overall,
there is tremendous opportunity to improve health care by advancing imaging techniques
and by developing novel biomarkers for many diseases. To this end, I collaborate with
numerous investigators spanning several departments and colleges, including UNM School
of Engineering.
My educational interest is focused on developing a medical physics pipeline for minority
and underserved communities in New Mexico. I direct a CAMPEP-accredited medical
physics graduate program within the Nuclear Engineering Department, and I developed
and direct a medical physics residency program within the Department of Radiology,
which recently received CAMPEP-accreditation. The accreditation team noted that our
program was one of the most comprehensive programs with over 800 competencies.
We are only 1 of 10 universities that offer both accredited programs. I also provide
fundamental medical physics education to radiology residents during our medical
physics teaching block and medical students in the Radiology Clerkship (Phase III).
Radiology residents receive both didactic and hands-on training, which is an optimal
method for teaching physics. I teach radiology residents and cardiology fellows and
directed the revision of the 80-hour Basic and Advanced Nuclear Medicine Authorized
User Course. The medical physics section is committed to providing the very best
educational environment for medical students, graduate students, and residents.
As a senior faculty member in Radiology, I am dedicated to mentoring junior faculty in
medical physics and radiology. I have mentored our two departmental clinical medical
physicists in clinical, education, and research areas and both were recently hired as
Assistant Professors in Radiology. I mentored our medical physics fellow, who was
recently hired as an assistant professor in our department, and mentored our first
medical physics resident, who is leading the medical physics program at Nellis Air Force
Hospital. I enjoy mentoring junior radiologists in neuroradiology and nuclear medicine by
meeting routinely to discuss research and scholarly activities. I actively mentor several
faculty members that includes 1 Associate Professor, 5 Assistant Professors, and 1
Lecturer. In addition, I mentor graduate students in biomedical sciences and medical
physics.
I oversee and provide clinical medical physics services for the University of New Mexico
hospital and Sandoval Regional Medical Center. I provide annual testing of imaging
Page 10 of 41
equipment, acceptance testing of newly installed scanners, and post repair or upgrade
testing to ensure optimal image quality and acceptable radiation dose. In addition, I
provide patient dose estimates such as peak skin dose for high dose fluoroscopy cases
and CT doses for wrongly imaged patients. I have special expertise in MRI physics and
MRI safety, I am certified by the state to provide mammography services, and I have
unique expertise in Y90 microsphere therapy and PET imaging. I develop room
shielding designs and review architectural plans to ensure that room construction meets
or exceeds state

Research and Scholarship

My research is focused on developing novel radioactive microspheres for imaging and treating liver cancer, and my lab is actively developing new resin and glass microspheres in collaboration with Chemical and Biological Engineering. Overall, we are interested in developing PET-based dosimetry for pre- and post-planning treatment of radiomicrosphere therapy. In addition to liver cancer therapy, I also actively study mild traumatic brain injury (mTBI) and use PET and MR imaging techniques to detect subtle brain changes. I have developed preclinical imaging facilities for the DOD and the University of New Mexico for studying brain injury and various cancer models.
