Sungwhan F. Oh, PhD

Assistant Professor, Harvard Medical School
Principal Investigator, CETRI
Department of Anesthesiology, Perioperative and Pain Medicine
Brigham and Women’s Hospital

Sungwhan received his bachelor’s degree in chemistry, summa cum laude, at Seoul National University in South Korea in 2003. He moved to Boston for his graduate studies in the Division of Medical Science at Harvard Medical School. In 2009, under the supervision of Prof. Charles Serhan, he defended his PhD dissertation on the biosynthesis and pro-resolving activity of endogenous lipid mediators. He continued his postdoctoral training on the gut microbiota and its immunomodulatory lipid mediators in the Department of Microbiology and Immunobiology, where he worked as a postdoctoral fellow (2011–2016) and an instructor (2017–2018) in the laboratory of Prof. Dennis Kasper, with support from Crohn’s and Colitis Foundation Research Fellowship Award (2013–2016) and NIDDK Research Scientist Development Award (2015–2020). Sungwhan joined the Center for Experimental Therapeutics and Reperfusion Injury (CETRI) in the Department of Anesthesiology, Perioperative and Pain Medicine at Brigham and Women’s Hospital in 2018. His research interest is focused on the use of high-sensitivity mass spectrometric platforms to identify and characterize novel molecular factors of gut symbiotic origin.

Ji-Sun Yoo, PhD

Postdoctoral Research Fellow

Ji-Sun received her B.S. in Biology, cum laude, in 2009 at Seoul National University, where she subsequently started her PhD work in the laboratory of Dr. Jung-Hye Roe. Her thesis focused on the stress response of Actinobacteria to reactive oxygen species and antibiotics. Ji-Sun earned her PhD in 2017 and joined the laboratory of Dr. Oh in September 2019. Her current research interest is focused on the roles of lipids produced by microbiota components in host health and disease.

Ledia Gebremedhin

Research Assistant

Ledia was born and raised in Addis Ababa, Ethiopia. In 2012, she moved to Boston and attended Bunker Hill Community College before transferring to Mount Holyoke College, where she graduated in 2018 with a BS in biological sciences. She joined the Oh lab in 2019 as a research assistant in charge of the gnotobiotic animals used by the group for various in vivo models.

Da-Jung Jung, PhD

Postdoctoral Research Fellow

Da-Jung received her BS in biochemistry from Chungnam National University in South Korea (2011) and her PhD in immunology from Pohang University of Science and Technology (POSTECH) in South Korea (2017). During her PhD training, which was mentored by Dr. You-Me Kim, she studied the cellular and molecular regulation of B cell responses and regulatory mechanisms of T cell receptor signaling. After postdoctoral training in Dr. Kim’s group (2018–2019), Da-Jung moved to Boston and joined the Oh lab. Her research interest is elucidation of the regulation of host immune systems by commensal microbiota–derived molecules.

Eun-Gyo Choi

Research Assistant

Eun-Gyo earned a BS in chemistry at Seoul National University and a DDS degree at Yonsei University in South Korea. She joined the Oh lab in 2020 and is currently working on lipidomic profiling of symbiont-derived immunomodulatory lipids.

Byoungsook Goh, PhD

Postdoctoral Research Fellow

Byoungsook received her bachelor’s degree in chemistry (2014) and Ph.D. degree in analytical chemistry (2020) at Gwangju Institute of Science and Technology (GIST) in South Korea. During her PhD training at GIST, she conducted her research related to development of an analytical platform for quantitative measurement of biomolecular dynamics under the supervision of Dr. Tae-Young Kim. Her current research is elucidation of lipid biosynthetic pathways associated with host immunomodulation in gut symbionts.
