Chao Guo PhD

Dr. Chao Guo, PhD, is a Diagnostic Medical Physicist at Cedars-Sinai Medical Center, a leading academic health system and research hospital in Los Angeles, California, where he contributes to clinical imaging quality, radiation safety, and quantitative evaluation of diagnostic procedures using advanced physics methods.

Dr. Guo completed his Doctor of Philosophy (PhD) in Medical Physics at the University at Buffalo Graduate School, where his training prepared him for clinical and research roles in diagnostic imaging physics, radiation dosimetry, and quality assurance. Before that, he earned his Master of Science (MS) from the University of Florida, also in Medical Physics.

In his current role at Cedars-Sinai, Dr. Guo applies his expertise in medical imaging physics—including X-ray imaging, Monte Carlo simulation, and radiation exposure assessment—to optimize imaging protocols, enhance patient and staff safety, and support high-quality diagnostic services. He has authored and co-authored technical publications and conference presentations focused on practical and task-specific evaluation of imaging systems, radiation dose estimation, and image quality metrics.

Dr. Guo’s work bridges clinical service and scientific investigation, advancing evidence-based improvements in imaging practice and contributing to the broader medical physics community’s efforts to integrate sophisticated physics methods into everyday clinical workflows.
