Dr. Chua is an assistant professor in the Department of Neurology and Division of Movement Disorders at  Johns Hopkins. He received his training at the University of Michigan, where he obtained medical and graduate degrees, then completed a residency in neurology and a combined clinical/research fellowship in movement disorders and neurodegeneration.

Dr. Chua’s primary research interests are in neurodegenerative disease with a special focus on autophagy — an essential housekeeping process in cells that is particularly important for the health of neurons. Autophagy may provide a way to break down the buildup of toxic proteins found in neurodegenerative diseases, thereby forming the basis of new treatment strategies for these incurable conditions. He has received multiple research grants to support his work, including from the National Institute of Neurological Disorders and Stroke and the American Academy of Neurology (AAN).

He is the primary author and co-author of multiple peer-reviewed scientific publications and online learning modules as part of the AAN. Dr. Chua is a contributing author to The Little Black Book of Neurology by Osama Zaidat, Alan Lerner and J. Douglas Miles, and he has been a peer reviewer for the scientific journals Autophagy, eLife and Neurobiology of Disease. He currently serves on the scientific advisory board for the Don't Forget Morgan Foundation, a private organization supporting research and outreach regarding the disease beta-propeller protein-associated neurodegeneration (BPAN). 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.
