December 11, 2023 at 1:00 pm - 5:00 pm

Wanye Gao

Wanye Gao, supervised by Dr. Jeffrey Andrews, will defend their thesis titled “Exploring Spatial Heterogeneity of Radiation with Radiochromic Film and Raman Spectroscopy” in partial fulfillment of the requirements for the degree of Master of Science in Mathematics.

An abstract for Wanye Gao’s thesis is included below.

Defences are open to all members of the campus community as well as the general public. Registration is not required for in person defences.


This thesis delves into a comprehensive analysis of EBT-3 films using Raman spectroscopy, aiming to elucidate the intricate spectral data and spatial heterogeneity associated with radiation exposure. The research two principal peaks serving as pivotal indicators of dose response, which display discernible intensity variations in tandem with dose levels. In juxtaposition, polyester peaks offer a contrasting tableau of stability, acting as markers of spectral consistency regardless of dose alterations. To further explore the spatial intricacies, Moran’s I was employed, revealing analogous patterns between dose-response peaks and Monte Carlo simulated doses, reinforcing the spatial coherence inherent in radiation exposures. A notable finding was the significant positive spatial autocorrelation exhibited by doseresponse peaks, suggesting the presence of underlying systematic patterns in the data. Further texture and consistency analyses were conducted using Haralick features, which underscored the textural and structural disparities across varied dose scenarios. In summation, this research uncovers the profound capabilities of Raman spectroscopy in deciphering the spectral characteristics intrinsic to radiation exposures and its potential applications in precise radiation dosimetry.
