For the last 12 years I have been working as a Neuroradiologist at McGovern Medical School at The University of Texas Health Science Center at Houston (UTHealth). I have the pleasure of working with medical students, residents, fellows, and faculty from the Radiology, Neurology, Neurosurgery, Infectious disease, and Ophthalmology departments. My clinical work has led me to specific areas of interest for research, such as Mitochondrial Diseases, Stroke, Pediatric Neuroimaging, and MRI safety. I enjoy creating educational materials that will enhance the learning experience for our residents and visiting students.
