Research Abstract:

My laboratory focuses on the characterization of perioperative neural markers of cognition and consciousness, with the goal of elucidating the mechanisms underlying reversible pathological recovery. The rationale is that interventions during the critical period of perioperative care may 1) enhance patient outcomes and 2) provide insight into underlying neural mechanisms for higher order brain function.

The current scope and rationale of my laboratory include three broad aims:

1) Elucidate the role of preoperative brain function during both sleep and wakefulness and on subsequent recovery in the postoperative period.
2) Characterize the changes in correlated brain activity and cognitive function associated with sleep, sedation, and general anesthesia.
3) Clarify the relationship of early postoperative neural activity and subsequent development and resolution of cognitive dysfunction.
