Group leader/Professor, Academy of Immunology and Microbiology (AIM), Institute for Basic Science (IBS), and Pohang University of Science and Technology (POSTECH), Republic of  Korea
 

Short Biography:

Dr. Im completed his PhD degree at the department of immunology, Weizmann Institute of Science by studying the development of antigen-specific immunotherapy to treat autoimmunity using experimental myasthenia gravis as a model. He then completed post-doctoral training at the Harvard Medical School where his work focused on the epigenetic regulation of cytokine gene regulation in the CD4 T. Dr. Im is currently Professor in the Division of Integrative Biosciences and Biotechnology, Pohang University of Science and Technology (POSTECH) and a Group leader, Academy of Immunology and Microbiology (AIM), Institute for Basic Science (IBS), KOREA, where he is applying this training to understanding how our immune system maintains immune homeostasis by balancing between the immunity and tolerance. His research provide a close link between basic research and translational approach to treat hyper-immune disorders such as autoimmunity and allergic disorders.

Research Interests: Dr. Im's laboratory has five main areas of interest: 1) Role of transcription factors (Ets1 and NFAT1) in immune regulation and Tolerance 2) Molecular mechanism of IL-10 gene regulation in lymphocytes and antigen presenting cells (DCs and macrophages). 3) Elucidation of the signaling pathways and underlying mechanism for IL-10 generation by probiotics. 4). Characterization of regulatory DCs and iTreg cells induced by probiotics. 5) Development of antigen-specific immunotherapy for autoimmune disorders (Myasthenia gravis and rheumatoid arthritis)
