I am a pharmacologist with over 28 years of academic and industry experience. As a professor of pharmacology at Hanyang University in Korea, I conducted research on G protein-mediated cell signaling and drug mechanisms. I also worked as a senior researcher at LG Life Sciences, focusing on early-phase drug development. My work has resulted in numerous peer-reviewed publications in pharmacology. Currently, I am active in medical writing, AI-assisted drug discovery, and science communication through my YouTube channel *Pharmalogue*.
