Dr. Cazalas has research interests in the application of nuclear and radiation physics for the design, development, and application of radiation detector technologies and science. Some of these applications include building and understanding detectors for neutron dosimetry, spectroscopy, imaging, detection systems for nuclear security, and testing detectors, dosimeters, and materials in various radiation environments.
Another area of interest is the development and testing of new nano and thin film materials, including quantum dots, in architectures designed for radiation sensing and/or hardness. This includes performing radiation exposure experiments of new semiconductor designs, including those that utilize 2d or quantum materials. This work involves building understanding of how various radiation types and energy interact with different electronic device components, and how the released energy (electrons) impact the function of these devices.
Dosimetry is an important component of work as it is required to assess the amount of energy absorbed into test objects of interest (e.g. detector crystals) or indicate a level of potential exposure to living beings (e.g. humans). Work in dosimetry focuses on quantifying dose with the development of new dosimeter designs, and by simulations. Work in dosimetry also includes minimizing unwanted dose, though effective shielding design, or reduction/elimination of potential exposure pathways.
Finally, the experimental work carried out in lab is guided through creating, executing, and understanding various computational simulations and models, such as Monte-Carlo based radiation transport codes (i.e. MCNP, GEANT4). These simulations provide a virtual testbed for efficiently testing new detector, dosimeter, and shielding designs and for comprehension of experimental setups or operational scenarios.
