Dr. Kim’s research focuses on the development of mathematical and computational models of transport-related biological systems, which includes characterization of light-tissue interaction, 3D tomographic imaging of physiologically relevant parameters in biological systems such as oxy-hemoglobin and deoxy-hemoglobin, 3D molecular imaging, and modeling of chemical species transport.
Dr. Kim has been applying these models and related technologies in preclinical and clinical studies that focus on the ultrahigh spatiotemporal resolution direct imaging of neuronal brain imaging, diagnosis of rheumatoid arthritis and Lupus in finger joints, the early detection and treatment monitoring of breast cancer, imaging of prostate cancer and risk stratification, cancer diagnostics and drug efficacy based on fluorescence and bioluminescence molecular imaging, assessment of peripheral arterial disease, Melanoma early diagnosis, and detection and monitoring of infantile hemangiomas.
