I am an anesthesiologist who specializes in the care of general surgery, off-site and neurosurgical patients. After completing residency training at the MGH, I joined the faculty at the MGH/Harvard Medical School while conducting research as part of the Harvard Anesthesia T-32 training grant. My area of expertise is in disorders of cognition, sleep and circadian rhythm, and neurotrauma. I have a background in computational neurosciences and non-linear dynamics that have enabled me to develop new prognostic tools in traumatic brain injury and further define mechanisms of anesthesia using electroencephalography. I currently work with Drs Kun Hu and Frank Scheer at the Brigham and Women’s Hospital Sleep Medicine group, Dr Oluwaseun Johnson-Akeju at the MGH, as well as Dr Richa Saxena at the Broad Institute to explore environmental (e.g. shiftwork), behavioral (e.g. sleep hygiene, meal timing, social jetlag) and genetic markers of poor cardiovascular (e.g. metabolic syndrome and diabetes), neurological (e.g. Alzheimer’s disease), and pain outcomes. My hope is to integrate these disciplines to improve the early detection and treatment of poor outcomes in the perioperative period (e.g. delirium, and post-operative cognitive dysfunction).
