  • My research project involves designing, building and testing a polarized energy dispersive x-ray fluorescence and energy dispersive x-ray diffraction system. The goal is to use this equipment to analyze biological tissue samples to help further our understanding of diseased tissue. X-ray fluorescence gives us the elemental composition of the sample, while x-ray diffraction will yield structural information. Together, these two sets of data can be used to classify unknown samples as diseased or healthy, and provide insight into disease development and prognosis.

  • I am currently involved in the NEUDOSE CubeSat team, as the Systems Engineer. Together with the project leader, Dr. Andrei Hanu, I help oversee the design and construction of the satellite and all its subsystems.

    I really enjoy the design aspect of both my research project and the NEUDOSE project. As such, I am very interested in designing and testing new medical and radiation science equipment.
