Sangwoon Chung received his undergraduate and Master of Science degree at Pusan National University in South Korea prior to obtaining a Ph.D. in Pharmaceutical Sciences from Kanazawa University in Japan. Dr. Chung joined Dr. Christman’s lab group at the University of Illinois at Chicago as a Postdoc Researcher, and in 2013 he moved with Dr. Christman to the Davis Heart and Lung Research Institute at the Ohio State University. Since joining The Ohio State University, he has developed expertise in many areas of pre-clinical animal models and subsequent analysis to define the role of alternatively activated macrophages in asthma pathogenesis.

Research Interests

  • Role of macrophages in asthma pathogenesis
  • Mechanism of electronic-cigarette-induced lung injury
  • The role of macrophages in ARDS and lung inflammation

Current Research

  • Defining a novel therapeutic tool using optimized exosomes-cellular components that exist outside the cell-to provide pre-clinical evidence for mitigating the inflammatory asthmatic features for neutrophilic severe asthma patients.
  • Sex-specific difference on mitochondrial dysfunction after Electronic-cigarette exposure that contributes to increased asthma exacerbations.
  • The hypothesis that recruitment and polarization of macrophages are important in airway inflammation in order to design new and effective treatments.
