Chan-Hyun Na, Ph.D. has extensive expertise in proteomics including LC-MS/MS-based mass spectrometry, imaging mass spectrometry, bioinformatics, and computer programming. In addition, he has been trained in neurodegenerative diseases and molecular biology. He obtained his Ph.D. from POSTECH, South Korea and then he moved to Konkuk University, South Korea where he established and optimized imaging mass spectrometry for biomarker discovery from renal cell carcinoma tissues. Subsequently, he joined Emory University, where he developed various proteomics methods using Fourier Transform-based mass spectrometry to study ubiquitin biology. After joining Johns Hopkins University, he has been involved in applying proteomics technologies for discovering biomarkers and disease mechanisms of various neurodegenerative diseases, elucidating novel protein-protein interactions in a variety of contexts, identifying cryptic open reading frames encoded in the human genome and identifying long-lived synaptic proteins by measuring turnover of synaptosome proteins. In addition, he served as research director of the Center for Proteomics Discovery, Johns Hopkins University School of Medicine completing over 120 proteomics projects successfully. He is currently an Assistant Professor in the Department of Neurology and the Institute for Cell Engineering. more

Patient Ratings & Comments

The Patient Rating score is an average of all responses to physician related questions on the national CG-CAHPS Medical Practice patient experience survey through Press Ganey. Responses are measured on a scale of 1 to 5, with 5 being the best score. Comments are also gathered from our CG-CAHPS Medical Practice Survey through Press Ganey and displayed in their entirety. Patients are de-identified for confidentiality and patient privacy.
