Laboratory for Sleep Neurobiology

Man agonizing about sleep

Focused on basic sleep and brain research, with ongoing studies that examine sleep-disordered breathing, circadian rhythm disorders, cognitive and cardiovascular consequences of disordered sleep, and narcolepsy

Katherine Durham Maki

Katherine Durham Maki, MS, APRN

Maki’s research focuses on the cardiovascular consequences of disrupted sleep (e.g., shift work, sleep fragmentation). She is interested in studying the mediating effect of the microbiome on cardiovascular pathophysiology, and the role of circadian misalignment in this model. As a cardiac electrophysiology nurse practitioner at the Jesse Brown VA Medical Center, her goal is to translate this research into interventions that reduce cardiovascular morbidity in veterans.

Sara Mithani

Sara Mithani, BSN

During her undergraduate studies, Mithani developed expertise in the application of high density electroencephalography to explore sleep function and neurophysiology. Currently she is studying optogenetic manipulations of cholinergic neurons in the pons to define sleep and cardiovascular function. Mithani is interested in identifying physiologic and genetic alterations following traumatic brain injury with a focus on sleep abnormalities and the development of neurodegenerative diseases.
