RESEARCH
EXPERTISE:
Dose Calculation Algorithms in Radiation Therapy - The first part of my career was devoted to the
development of novel algorithms for the calculation of dose in radiation therapy treatment planning. My
work on Monte Carlo algorithms and the convolution / superposition algorithms was incorporated into the
commercially available treatment planning systems, and is now considered the state-of-the-art algorithm.
I continue to work on this clinical research area, with the on-going development of a new Monte Carlo
based algorithm that explicitly accounts for density and atomic composition of the human body.
Inhomogeneity Corrections in Treatment Planning - I have been investigating the effect of tissue
heterogeneity on dose prediction for photon beams for several years. I have an extensive publication
record in this area, and I chaired the Task Group for the American Association of Physicists in Medicine
(AAPM) that developed the Standard of Practice for dose calculation with the inclusion of tissue
heterogeneities. I continue to work in this area and study the effect of tissue heterogeneity in the delivery
of hypofractionated regiments to lung and upper GI patients with stereotactic Body Radiotherapy.
Intensity Modulated Radiation Therapy - Over the past ten years, I have worked in the development of
novel techniques for the planning and delivery of complex beams that conformally deliver the prescribed
dose to the target. This area of research parallels my clinical interest in image-guided radiotherapy. My
collaborators and I have developed several algorithms and software tools that have enabled us to
improve on the accuracy and the quality assurance of intensity modulated radiation therapy. I developed
a clinical training course for physicians, medical physicists, and dosimetrists to share the clinical tools
that we have developed and implemented, and I have published and presented extensively in this area.
We continue this research effort with the inclusion of biological evaluation and optimization of treatment
plans based on toxicity data. We have already published in this area and we have an active collaboration
with Karolinska Institute in Sweden to further exploit the possibilities of a radiobiologically based
treatment planning environment in radiation therapy.
PROJECTS:
Curriculum Development
07/200812/2008
Medical Residency Program, Developed a one-year residency training program for
master‘s level medical physics graduates, compliant with American Association of
Physicists in Medicine program guidelines at the University of Texas Health Science
Center at San Antonio
01/200609/2007
Medical Residency Program, Developed a new curriculum for the medical residency
program based on the American Society of Therapeutic Radiation Oncologists / American
Association of Physicists in Medicine training guidelines at the University of Texas Health
Science Center San Antonio.
01/2006Present
Medical Dosimetry Training Program, Restructured curriculum and developed formalized
coursework (instead of on the job training) for the Medical Dosimetry training program at
the Cancer Therapy and Research Center.
01/2006Present
Medical Physics Graduate Clinical Practicum, Developed a two year program offering
clinical experience for those students enrolled in the graduate medical physics program at
the University of Texas Health Science Center San Antonio. The clinical practicum
curriculum was designed to expose the student to all aspects of clinical medical physics in
radiation therapy. Through individual instruction and under the supervision of the faculty
medical physicist the student performs a number of defined tasks and documents his
progress in well defined checklists for each rotation.
05/200111/2005
Medical Physics Residency Program, Developed a two-year residency training program
for master‘s level medical physics graduates, compliant with American Association of
Physicists in Medicine program guidelines at the University of Arkansas for Medical
Sciences
05/200108/2004
Medical Dosimetry Bachelor of Science program, Developed the curriculum for this
degree-granting program (one of three formal programs in medical dosimetry in the
country) at the University of Arkansas for Medical Sciences.
Departmental Projects
05/200110/2005
Clinical Program Development, Established a medical physics program in the Department
of Radiation Oncology at the University of Arkansas for Medical Sciences. This was a new
department that was set up with new equipment. I assembled a medical physics group;
we established several clinical programs including: Intensity Modulated Radiation
Therapy, tomotherapy, total body and total skin radiotherapy, respiratory gated imaging
and delivery of radiotherapy, digital imaging with electronic portal imaging (EPID) and
photostimulable phosphor cassettes, real time image based prostate brachytherapy in the
operating room, Gamma knife radiosurgery, High Dose and Low Dose Rate
comprehensive brachytherapy. In addition to the clinical development there was teaching
of the student therapists, medical dosimetrists, and medical physics residents on the use
and development of clinical protocols for those new treatment modalities.
05/200110/2005
Stereotactic Radiosurgery, After completing a Gamma Knife stereotactic radiosurgery
training course, I developed a comprehensive stereotactic quality assurance program at
the University of Arkansas for Medical Sciences. In addition to clinical protocols, it
contained a database that was created for patient data entry and outcome analysis. A
Training and Procedure Manual was also developed which was used for the training of
medical residents, medical physics residents, and dosimetry students.
Teaching Projects
03/2008Present
Medical Dosimetry Board Review Course, Developed a review course that is offered
nationally to medical dosimetry students and junior medical dosimetrists that are preparing
to take the board certification examination. The course offers 20CE credits
03/200303/2003
Developments in Modern Treatment Planning and Radiation Delivery Techniques,
Organized and delivered a week long teaching and refresher course on new
developments in intensity modulated and image guided radiation therapy. The course was
held at the IASO teaching hospital in Athens Greece and was attended by medical
physicists, radiation oncologists and medical oncologists.
07/199402/2000
Review course on modern treatment planning algorithms, Developed the curriculum and
taught this course to practicing clinical medical physicists from the US and abroad. This
was a symposium-style teaching course that was offered six times a year for three days,
of which I taught one day, on the physics of modern treatment planning algorithms.
