Profile Navigation


Hunki Paek, Ph.D., currently serves as Associate Research Scientist at Columbia University Medical Center, where he specializes in basic science research regarding the hearing loss and potential therapy. Dr. Hunki Paek graduated from Korea University and obtained his Ph.D. of Genetics and Neuroscience in Albert Einstein College of Medicine. After his Ph.D. he started to work at Columbia University Medical Center investigating cell surface markers of putative quiescent adult neural stem cells from their in vivo niche and characterizing a novel protein PDZD8 involved in ER-Mitochondrial tethering of neurons in the mouse brain. At Columbia University Medical Center the research of Dr. Hunki Paek is focused on understanding cellular and molecular changes in the peripheral/central auditory system in response to noise-induced hearing loss.
