Meghan Rossi is a PhD student in the UCSD Neurosciences Graduate Program. As a member of Dr. Richard Daneman's lab, Meghan is focused on examining the effects of peripheral factors, including dietary intake and exercise, on the special properties of the blood vessels in the brain termed the "blood-brain barrier." In addition, she is interested in the role of blood-brain barrier circadian rhythm on Alzheimer's disease pathogenesis, as well as the potential role of the gut microbiome in modulating properties of the blood-brain barrier.
