Former Director of Proton Therapy, Dept. of Radiation Oncology, University of Miami Sylvester Comprehensive Cancer Center.

Adjunct Clinical Professor, Dept. of Radiation Medicine and Applied Sciences, University of California at San Diego.

Co-Chair of the Publication Committee and member of Executive Committee of PTCOG (Particle Beam Therapy Co-Operative Group) (2013 – 2019.)

Co-Editor-in-Chief for the International Journal of Medical Physics, Clinical Engineering, and Radiation Oncology.

Co-Editor-in-Chief for the Translational Cancer Research Journal.

Dr. Giap received his graduate degree in nuclear engineering (cum laude) from Texas A&M University in 1986. After working at a commercial nuclear reactor in Texas for several years, he was accepted into the M.D./Ph.D. Medical Scientist Training Program at the University of Texas Health Science Center at Houston (UTHSCH), where he completed both Medical Doctor and Doctor of Philosophy in Medical Physics degrees at the University of Texas M.D. Anderson Cancer Center in 1994.

For his dissertation, he developed a three-dimensional treatment planning software for systemic radionuclide therapy, and his research won him the award at the Young Investigator Symposium at American Association of Physicists in Medicine annual meeting 1993. He did his residency training at Loma Linda University Medical Center with focus on proton beam therapy. After that, he completed a clinical fellowship at Scripps Clinic in stereotactic radiosurgery and brachytherapy.

He worked as a clinical radiation oncologist at Scripps Clinic from 1998 to 2008. He was the Director of Clinical Research and Chief of GI, Lung, and Breast at the Scripps Proton Therapy Center.

While serving on PTCOG’s Publication Committee and Executive Committee,  he created subcommittees for GI, H&N, breast sites. As PTCOG’s Congress President, he organized and hosted the annual international PTCOG 54th annual meeting in San Diego for 2015.

He has done research in, published, and given talks in the field of particle beam therapy, vascular brachytherapy to prevent coronary artery restenosis, biophysical modeling, radio-labeled antibody, stereotactic radiosurgery, partial breast irradiation, and radio-embolization with Y-90 microspheres.

He has an affiliated volunteer appointment of Clinical Professor in the Department of Radiation Medicine and Applied Sciences at UCSD and is currently developing the University of Miami’s proton therapy program.

He is the editor for the book “Particle Beam Therapy: Contemporary Trends and Reviews” (AME Publishing 2014). He was one of the contributors to the American College of Radiology (ACR) and American Society of Radiation Oncology (ASTRO) for several clinical guidelines (Radioembolization with Brachytherapy Device Yttrium-90 micro-spheres and Total Body Irradiation). He gave refresher courses at the annual ASTRO national meetings (2001, 2005, and 2006) on the topic of “Vascular brachytherapy” and “Radiation therapy for benign diseases.” He served as a member of the ASTRO Annual Meeting and Program committee as well as the Information Technology Development and Resource Committee.
