David M. Gauntt, Ph.D. earned a bachelor’s degree in physics from the Massachusetts Institute of Technology, and a Ph.D. in physics from Stanford University. He spent two years as a Medical Physics Fellow at UAB Radiology before entering industry.

During seven years at Lunar Corporation (now GE Lunar), he was instrumental in the development of the Expert fan beam bone densitometer and the Pixi extremity bone densitometer.

He returned to Birmingham to work at X-Ray Imaging Innovations, a UAB spinoff company founded by Dr. Gary Barnes.   While at XRII, he was principal investigator in several projects funded by the National Institutes of Health, developing improved methods of scatter rejection in radiography, mammography, and fluoroscopy.

In 2011 he joined the faculty of UAB Radiology as an Associate Professor in the Division of Medical Physics and Engineering, where he oversees the x-ray quality assurance program and helps with resident teaching.

He has served in several national professional organizations, most recently as a member of the AAPM Task Group 150, the RSNA/AAPM Task Force for Online Medical Physics Education, and the ABR Diagnostic Medical Physics Part II exam writing committee.

He has continuing research interests in scatter control in fluoroscopy, application of dual energy imaging in dentistry and in CT, and the use of physics simulation software in medical physics education. He also works with the BEST Robotics program to help science and technology education in middle school and high school.

Gary T. Barnes, Ph.D., DABR, FAAPM, FACR

Retired Professor Emeritus, Division of Physics and Engineering

Dr. Barnes is the immediate past head of the Radiologic Physics Section and oversees the physics courses given for radiology residents. He teaches the popular 4-month series of board review sessions for Senior residents in addition to several sections of the main physics courses. (Most year's resident classes score at or above the 90th percentile nationwide.) His research interests include image optimization and dose reduction in mammography, stimulable phosphors, and scatter reduction. He also develops new approaches to dual-energy imaging and computed radiography of the chest. Dr. Barnes is a two-time recipient of the Radiology Teacher of the Year Award and is a past president of the American Association of Physicists in Medicine.

Jian-xiong Wang, Ph.D., CCPM-MRI earned his bachelor’s degree in nuclear science from Fudan University, Shanghai, China, followed by a Ph.D. in physics from University of Paris-Sud, France.

After a postdoctoral fellowship at University of Guelph, Ontario, Canada in the Physics Department, Dr. Wang became a Scientist in the USA-Canada-UK collaborative Sudbury Neutrino Observatory which proved neutrino oscillation. As a team member, Dr. Wang was awarded the 2016 Breakthrough Prize in Fundamental Physics.

Dr. Wang joined the Medical Physics field in 2000, and became a certified medical physicist specializing in MRI Physics in 2005. He became an MRI Scientist at GE Healthcare in 2006 developing multi-nuclear MRI system and methodology. In 2013, he became a faculty member in Radiology at UTSW, where he worked on metabolic MRI physics.

Dr. Wang is now an Associate Professor in the Physics and Engineering Division of the Radiology Department at UAB.

Dr. Wang has a broad background and experience in medical imaging physics, especially a wide range of expertise in MRI systems including RF sequences and RF coils. Dr. Wang is also interested in compressed sensing, parallel imaging, and machine learning applied in medical imaging.
