Stavros Melemenidis, PhD

I am a physicist and radiation biologist and a first-year Medical Physics Resident at the University of Colorado Anschutz Medical Campus. My academic journey began with a B.S. and M.S. in Physics—where I specialized in radiation modalities, detector instrumentation, and quantitative dosimetry—and continued through a second M.S. and D.Phil. in Radiation Biology. During a five-year postdoctoral fellowship, I designed and characterized both primary and metastatic murine tumor models and pioneered in vivo, contrast-enhanced molecular imaging strategies to detect micrometastatic disease and evaluate combined pharmacologic–radiation therapies.

Before residency, I served as Director of the Pre-clinical Radiotherapy Core in Stanford’s Department of Radiation Oncology, leading:

• Dose-calibration methodologies for orthovoltage irradiators and TrueBeam linac configurations


• Quality-assurance protocols and custom shielding/anesthesia solutions for small-animal FLASH and conventional studies


• Cross-functional collaboration with biology and engineering teams to translate ultra-high dose-rate research into reproducible workflows

As a new resident, I will rotate through external-beam, brachytherapy, and diagnostic-imaging services—developing expertise in treatment planning, machine commissioning, and collaborative clinical care. My long-term goal is to incorporate cutting-edge radiobiological insights and precision-dosimetry methods into everyday practice to enhance patient outcomes and overall treatment experience.
