Radiology Personnel

David Zamora, MS, DABR

Medical Physicist
Diagnostic Physics


David is a Texas native with a background in engineering. He took a position as a Physics Technologist at MD Anderson Cancer Center in Houston, TX where he learned the fundamentals of being a Diagnostic Medical Physicist.  Now David enjoys using that experience in the wide variety of clinical settings offered at the University of Washington.  In his spare time, he loves spending time with his expanding family while exploring the Pacific Northwest.

Research Interests

David is primarily involved in research projects with a clinical or practical emphasis, often focused on process-driven implementation/improvement or radiation dose calculation.
