Professional Background

Jiwoong Choi, PhD, is a research-track assistant professor of Division of Pulmonary, Critical Care and Sleep Medicine (chief: Mario Castro), Department of Internal Medicine, University of Kansas School of Medicine and affiliate professor of Department of Bioengineering, University of Kansas. Dr. Choi received B.S. and M.S. at Seoul National University, studying turbulent flow simulation in Mechanical Engineering. Dr. Choi joined the University of Iowa in 2005, and has studied CT image-based lung modeling and structural and functional relationships in normal and diseased human and animal lungs since then, through Ph.D. (advisor: Dr. Ching-Long Lin at Mechanical Engineering) and Roche Postdoctoral Fellowship (co-mentors: Dr. Ching-Long Lin at Mechanical Engineering and Dr. Eric A. Hoffman at Radiology; Biomedical Engineering; Internal Medicine) programs. After working in Seoul National University Hospital as a senior researcher in 2015 and 2016, Dr. Choi joined back in the University of Iowa as a research scientist of IIHR-Hydroscience andamp; Engineering. Dr. Choi joined University of Kansas School of Medicine in January 2020 as an expert in pulmonary imaging and computational modeling. Dr. Choi continues collaborative contribution as an adjunct professor of Department of Mechanical Engineering at the University of Iowa and an adjunct senior researcher of Department of Radiology at Seoul National University Hospital. The uniqueness of his research comes from multidisciplinary approaches including quantitative CT imaging, image processing, and computational modeling such as computational fluid dynamics (CFD) simulations. Cross-volume and cross-time CT image matching via image registration and 3D-1D coupled CFD simulations of pulmonary gas flow and particle transport in the entire conducting airways, using supercomputing resources, empowers to investigate multiscale lung structural and functional phenotypes and imaging biomarkers. Recent implementation of machine learning has delivered cluster-guided subject-specific characterization for inhaled particle deposition in asthma and COPD, being extended to bronchial thermoplasty response in asthma. Dr. Choi has been studying physiological and pathophysiological features in normal lungs as well as a variety of lung diseases, including asthma, chronic obstructive pulmonary disease (COPD), interstitial lung disease (ILD), lung metastasis of cancer, and environmental lung diseases.
