I am the Principal Investigator of the Radiological Physics Laboratory. With over two decades of experience as a trained clinical radiation oncology physicist and research scientist at various institutes in the USA and Canada, I bring a unique perspective to the everyday challenges encountered in the clinical practice of medicine. This extensive background in clinic informs and guides my research.
Lordina worked on investigating the radiochromic films for radiotherapy of cancer patients
Rania will investigate thermoluminescent materials for dose measurements
During her MS in Medical Physics, Ravneet focused her graduate research on addressing the computational challenges of targeted alpha particle therapy involving chain emitters. This therapy is gaining interest due to its ability to selectively target and destroy cancer cells while sparing healthy tissue. However, the decay chains of radionuclides such as Th-227, Ra-224, and Ac-225 present significant challenges in activity measurement due to complex ingrowth, decay behavior of progeny, and uncertainties in nuclear decay data.
Aaron graduated with an MS in Medical Physics, before starting his clinical residency training. His graduate research focused on chemical dosimetry, specifically using ferrous ammonium sulfate, also known as Fricke dosimetry, to measure radiation doses from high-energy photon beams
Shadab pursued his Ph.D. in volumetric modulated arc therapy (VMAT) for multiple energy photon beams. His groundbreaking research focused on solving nonlinear optimization problems for full 360-degree arcs across various energies simultaneously, resulting in the creation of fluence maps. He then converted these fluence maps into contiguous MLC patterns, successfully delivering and verifying the concept through phantom measurements. This innovative approach demonstrated significant robustness in treating deep-seated tumors.
Philip's Ph.D. research addressed the limitations of intensity modulated radiotherapy (IMRT), which uses a single photon energy spectrum ( mostly 6 MV) for all treatment beams. Traditional IMRT, allowed only for the optimization of spatial modulation of photon fluence. However, the single photon energy spectrum deposits most of its energy near the surface, which is less effective for deeper tumors. Philip's work focused on optimizing photon beam energy and spatial fluence for various organ geometries and beam angles, aiming to develop a new modality called modulated photon radiotherapy (XMRT). This approach to achieved a dose distribution that closely matches the desired outcome specified by radiation oncologists.
