Since the first public demonstration of ether anesthesia in 1846 (here in Massachusetts), the majority of general anesthetics are accomplished by administering the primary anesthetic agents by inhalation.  Not so for many of my patients.  I prefer administering general anesthesia exclusively via the intravenous route. Intravenous anesthesia is not demonstrably safer nor associated with superior outcomes, but to me it is a lot more intellectually satisfying. Intravenous anesthetic agents also do not smell bad. Most general anesthetic agents given by inhalation smell like dry-cleaning fluid (to which they are closely related chemically!)

My other primary interests in teaching residents are in the areas of preventing postoperative nausea and vomiting, an unpleasant (for both patient and anesthesiologist) but unfortunately still common occurrence, and measuring the depth of anesthesia using the newly-introduced EEG monitors.  Not only was I a co-investigator on an early trial in the development of the BIS monitor, but I was also a volunteer participant.  The fact that a small, but significant, portion of the BIS algorithm is based upon the evaluation of my own EEG waves while under propofol anesthesia may or may not make the anesthesia community feel more confident in this new technology.

I am intimately involved in almost every facet of a resident's training at UMass, from interviewing virtually every applicant to roasting every graduate at our yearly graduation banquets.  As part of our comprehensive didactic program, once a week I preside over our review sessions for the written board exams.  Having authored the best-selling review book in our specialty (McGraw-Hill Specialty Board review: Anesthesiology), I feel that I am in a unique position to help our residents prepare for this dreaded exam.  While we undertake our weekly review of board exam questions, we also eat pizza (50% with meat, 50% without) because pizza is an obligatory part of anesthesiology.  I have also sat in on real oral board examinations and coordinate our department's mock oral exams given to our residents.

My hobbies (that my wife insists are too numerous and time-consuming) include tinkering with vintage electronic devices, computer hacking, and still and video photography.  A paradox is that I aim to have the newest and fastest computer equipment while still relying on vacuum tube technology in my audio system.  I am also the unofficial photographer and videographer for the department.
