"As a prospective graduate student for medical physics, I wanted to get as much experience as I could with research. Academically, my goals for the year include: seeking out and applying to multiple medical physics programs, complete my research project and write a technical paper on it, and graduate with my degree in nuclear engineering sciences from UF."
Nuclear Engineering Sciences
Academically I am interested in nuclear engineering as well as mathematics and physics. My research interests pertain more to the medical physics department, more specifically with phantom construction and CT (Computed Tomography) mA-modulation.
Academic and Other Awards
- University Scholars Program Scholarship (2011-2012)
I have volunteered at Shands Hospital in their radiology department.

Quantifying Organ Dose Reduction using Tube Current Modulation in CT
Under the supervision of Dr. Wesley Bolch, Elliott Stepusin constructed an anthropomorphic phantom to evaluate organ dose measurements using a fiber optic dosimetry system developed by Hyer. The purpose of this study was to validate Monte-Carlo simulations on a 3D-computational hybrid phantom(UF10MF). The study focused on tube current modulation techniques used in CT imaging. The phantom was constructed using soft tissue, lung tissue, and bone substitutes that represent the attenuation characteristics at diagnostic energies. The phantom consisted of a series of 5mm slices of the tissue equivalent substitutes. Each slice was generated by a milling machine that outlined the soft tissue regions. These voided regions were filled with the soft tissue substitute and finished with the lung and bone equivalents. Slices were than grouped according to strategically positioned dose points. Fiber optic dosimeters were later placed at these dose points to evaluate organ doses with and without tube current modulation. These measurements will be compared with the calculated computational values.
