Expertise and Research Interests
More than half of the cancer patients receive radiation treatment. The goal of radiation treatment of cancer is to deliver a lethal dose to the tumor volume without exceeding the tolerance of surrounding normal tissues. This is achievable by current treatment techniques for about half of the patients receiving radiation with a curative intent. About half of these patients fail locally within the tumor volume itself. Our research is aimed to benefit these patients who should not have failed locally. The overall objective of the research in radiological physics is to develop and utilize new physical techniques of tumor and normal tissue imaging, dose calculations, dosimetry measurements and delivery techniques, and to develop new physical modalities such as new brachytherapy sources, new radiation devices, etc. Current projects include development of superheated drop detectors, development of samarium-145 and americium-241 brachytherapy sources, electronic portal imaging, stereotactic radiosurgery, ultrasound-guided transperineal implantation of radioactive iodine-125 or palladium-103 sources in prostate cancer patients.
Other Expertise
I wish to be contacted by interested students (medical, graduate or undergraduates) as a potential research mentor/thesis advisor.
