Dr. Thai is also the residency program site director for Suburban Hospital. He is board certified in neurological surgery by the American Board of Neurological Surgery and practices out of Bethesda, Maryland.

Dr. Thai has expertise in treatments of the degenerative spine, including neck and back pain, disc herniations and stenosis, which may require surgery using minimally-invasive techniques or traditional open procedures. Dr. Thai performs surgery for primary and metastatic brain tumors using computer-assisted neuronavigation. He also evaluates and treats patients on an outpatient basis for issues such as carpal tunnel syndromes and compression fractures. He specializes in adults, ages 18 and older. 

Dr. Thai earned his medical degree from The Johns Hopkins University School of Medicine and earned a graduate certificate in Business of Medicine at The Johns Hopkins Carey Business School. He completed a residency in neurosurgery at The Johns Hopkins Hospital, where he served as chief resident and became an advanced specialty trainee in spine, oncology and vascular neurosurgery. Dr. Thai also served as senior resident of neurosurgery at Johns Hopkins Bayview Medical Center and completed a fellowship in cerebrovascular research at The Johns Hopkins University School of Medicine. He is currently part of the Management and Leadership Executive Certificate Program at Massachusetts Institute of Technology. 

Dr. Thai previously owned his own neurosurgery practice in North Carolina. He has taught many Continuing Medical Education (CME) courses and has also served as a clinical assistant professor of neurosurgery at the University of Texas Medical School at Houston.

Dr. Thai is a fellow of the American Association of Neurological Surgeons and the American College of Surgeons. He is also a board medical consultant in neurosurgery for the Maryland Board of Physicians and a consultant in neurological devices for the Medical Devices Advisory Committee of the Center for Devices and Radiological Health in the Food and Drug Administration. 

Dr. Thai has earned many scholarships and awards for his research, such as the Agustus McCravey Resident Research Award from the Southern Neurosurgical Society, the Harvey Cushing Neuroscience Research Award from Johns Hopkins University School of Medicine and the Michael J. Stanton, M.D., Surgeon of the Year Award from Suburban Hospital. He has contributed to numerous publications, book chapters and abstracts with his research. He was part of a clinical study that focused on the efficacy of shunt surgery in normal pressure hydrocephalus. Dr. Thai is on the editorial board for Techniques in Neurosurgery & Neurology, and has acted as a guest editor and peer-reviewer for scientific papers and articles. more
