Dustin Valdez
Postdoctoral Researcher
I am a Postdoctoral Researcher at the University of Hawaiʻi Cancer Center, building on my PhD in Nutritional Sciences at UH Mānoa. My research focuses on cancer prevention and risk stratification in medically underserved and multiethnic populations, integrating deployable imaging technologies, epidemiology, and interpretable artificial intelligence. During my doctoral training, I investigated breast cancer disparities among Native Hawaiian women using population-based cohort and registry data, clarifying the role of metabolic risk factors in shaping cancer incidence and stage at diagnosis. In my postdoctoral work, I am expanding this program to metabolic dysfunction–associated liver disease and hepatocellular carcinoma, developing structured imaging-based models to support equitable, scalable cancer prevention strategies. I am committed to advancing data-driven, prevention-focused frameworks that translate rigorously evaluated technologies into real-world impact in resource-constrained settings. In my free time, I enjoy practicing taekwondo and taiko drumming.
