Description of Research Expertise

Research interests

Current research is focused on the effects of anesthesia and surgery on a vulnerable brain. Our recent studies have shown that surgery with an inhaled anesthetic, but not with propofol, resulted in significant and long-term cognitive impairment in pre-symptomatic Alzheimer mice, possibly due to the transient increase in neuroinflammation and an impaired immune response. In humans, we found significant changes in Alzheimer biomarkers in the CSF of patients during the perioperative period. Further research is underway to examine ways to modulate neuroinflammation after surgery and major illness.
