Thomas Mazur, PhD, is an instructor in radiation oncology. He joined the faculty in 2016. He received his PhD in physics at The University of Texas at Austin in 2014, where his doctoral work focused on the development of novel methods of controlling atomic motion with interests in both basic and applied science. This work culminated with an experimental realization of an efficient and scalable technique for stable isotope enrichment. By way of a non-profit foundation, The Pointsman Foundation, this technique will be applied toward the enrichment of stable precursors for the efficient generation of radioisotopes with both therapeutic and imaging applications. Tom is also interested in advancing image-guided radiation therapy, particularly by way of MR guidance. Tom has contributed to ongoing work – such as the development of efficient tools for both motion tracking and dose calculation – that should enable the implementation of advanced feedback of treatment delivery derived from measurements of tumor motion and accumulated dose. Additionally through collaborative efforts, Tom is interested in the application of advanced mathematical methods for refining the predictive capabilities of radiomics, and the development of novel materials for optically stimulated luminescence dosimetry.
