Brief Bio:
Dr. Li joined the Cleveland State University in Fall 2013. Her research is in the physics of medical imaging. In particular, she is interested in the assessment and reduction of radiation dose from clinical imaging procedures. One area of her research has been patient-specific organ dosimetry in computed tomography (CT). She develops Monte Carlo simulation models for multi-slice CT systems and performs organ dosimetry studies for patients of various ages and body sizes. Her work in pediatric CT showed that organ dose and cancer risk index can be estimated for individual patients based on age, gender, and a simple measurement of the patient's body circumference. Another area of her research has been protocol optimization in pediatric CT. For the detection of lung nodules representing pulmonary metastatic diseases, her work has established the continuous degradation of diagnostic accuracy with incremental dose reduction. Dr. Li collaborates with imaging physicists at the Cleveland Clinic Foundation and scientists in the medical imaging industry.

Before coming to CSU, Dr. Li completed her residency in imaging physics at Duke University Medical Center. She is certified by the American Board of Radiology (ABR) in Diagnostic Medical Physics.
