Young-Hoon Ahn, PI
ya426@drexel.edu

Ahn received his B.S. and M.S. degrees in Chemistry from Pohang University of Science and Technology (POSTECH) in Korea. He received his Ph.D. in Bioorganic Chemistry from New York University working with Professor Young-Tae Chang. His research focused on the development and application of fluorescent bio-imaging probes. He did his post-doctoral research in Pharmacology at Johns Hopkins University School of Medicine with Professor Philip A. Cole. His post-doctoral research focused on investigating cysteine-based signaling pathways with chemical probes. He began his tenure-track faculty position in the Department of Chemistry at Wayne State University in 2012 and was promoted to Associate Professor in 2018. He moved to Drexel University Department of Chemistry in 2022.
