Dr. Ramani is an Associate Professor for the Division or Neuroanesthesia, and comes to us from Yale University School of Medicine where he was an Associate Professor in the Department of Anesthesiology. Dr. Ramani earned his Bachelor of Science, Bachelor of Surgery from Delhi University in India. He completed his Medical Degree at the Institute of Medical Education and Research in Chandigarh, India. Dr. Ramani worked at Maimonides Medical Center in Brooklyn, New York, for his residency training, where he was Chief Resident, and he completed a Neuroanesthesia Research Fellowship at the University of Iowa. He is also approved by the National Board of Examination in New Delhi, India, and is certified by the American Board of Anesthesiologists. Dr. Ramani’s primary research focus is in functional MRI and its applications in anesthesia. He is an active member of the Education Committee of the Society of Neuroanesthesia and Critical Care and the Postoperative Visual Loss study group. He serves as an ad hoc reviewer for many journals such as Anesthesia & Analgesia, European Journal of Neurology, and PloS ONE, just to name a few. We are excited to have such an accomplished doctor joining us, and we ask you to help us welcome him to the department and university!

Research Interest:

Primary focus of research is functional MR imaging and its applications in anesthesia. Listed below are the fMRI studies done by our research group at the Yale Magnetic Resonance Research Center: Anesthesia fMRI studies carried out from 2003 to now in healthy volunteers: 1) Effect of 0.25 MAC sevoflurane on visual, auditory and motor activation 2) Effect of 0.25 & 0.5 MAC sevoflurane on auditory activation 3) Effect of 0.25 & 0.5 MAC sevoflurane on memory activation 4) Effect of 0.5 MAC sevoflurane on functional connectivity 5) Effect of 0.5 MAC sevoflurane on rCBF as measured by pulsed arterial spin labeling technique 6) Effect of 0.5 MAC sevoflurane on somato-sensory activation 7) Effect of 0.5 MAC equivalent propofol (2 µg/mL plasma level) on functional connectivity, rCBF and GABA, glutamate. 8) Fluorine imaging under 0.5 MAC sevoflurane anesthesia in volunteers.
