Graduate Student Researcher

Ph.D. student in Biomedical Engineering at the University of California, Davis, conducting research in advanced medical imaging, with a focus on Positron Emission Tomography (PET) and the development of accessible, cost-effective imaging technologies. My current research focuses on “Physics-Guided Emulation of J-PET Using Degraded uEXPLORER Total-Body PET Data to Enable Virtual Clinical Studies.” This work investigates how controlled degradation of uEXPLORER PET data can emulate the imaging characteristics of J-PET, enabling systematic evaluation of image quality and quantitative performance through virtual clinical studies.

With a background in Diagnostic Radiography and clinical imaging, I bring a clinical perspective to biomedical engineering research, bridging imaging physics, computational image reconstruction, and healthcare delivery. My broader research interests include advancing innovative, affordable, and accessible diagnostic imaging technologies to expand access to high-quality medical imaging globally.
