Dr. Miranda M. Lim, MD, PhD, is an Associate Professor in Neurology at Oregon Health & Science University and a Staff Neurologist and Principal Investigator at the VA Portland Health Care System. She is the Director of a basic and translational research program called Sleep & Health Applied Research Program (SHARP).

Dr. Lim earned a combined MD/PhD degree from Emory University in Atlanta in 2006. She then completed a neurology residency at Washington University in Saint Louis in 2010. There, she studied the role of orexin and the sleep-wake cycle in a mouse model of Alzheimer’s disease; these studies revealed that sleep and orexin modulate the deposition of amyloid plaques in the brain (Kang, Lim et al., Science 2009). She completed fellowship training in Sleep Medicine at the University of Pennsylvania and an NIH T32 postdoctoral fellowship studying sleep and traumatic brain injury (TBI) (Lim et al., Science Translational Medicine 2013). She received a VA Career Development Award early in her career and her research is current supported by VA, DoD, NSF, and NIH to uncover the mechanisms by which sleep promotes brain health in a variety of neuropsychiatric disorders including TBI, PTSD, autism spectrum disorder, Parkinson’s Disease, and Alzheimer’s Disease.
