Research Interests

As the director of the Arthroplasty Service at the Hospital for Special Surgery, I am continually presented with clinical scenarios that serve as the basis for my published research. Whether it's understanding whether or not a patient really needs a certain test before a procedure, or understanding an elevated heart rate after a procedure, I find the daily dilemnas of perioperative care point me towards avenues of research that are of a high clinical importance in orthopedic surgery.

In my role as a medical director for an orthopedic surgical service, I am able to collaborate effectively with my surgical colleagues to address clinical issues relevant to the orthopedic patient. For example, through collaboration with colleagues in my own department as well as the Departments of Orthopedic Surgery, I published a project to the Journal of Arthroplasty examining the role of End Tidal CO2 in assessing patients for pulmonary embolism in the post-operative period.

I also recently collaborated with colleagues in the Department of Population Health and the Department of Anesthesia to complete "Use of Pre-Operative Testing and Physician Response to Professional Society Guidance," examining national trends in the use of pre-operative testing and published in JAMA Internal Medicine.

Finally, I am collaborating with my colleagues in Orthopedic Surgery and Rheumatology to address the best way to identify who may have a pulmonary embolus after surgery.
