Research Areas

  • Alterations of the Nitric Oxide Physiology in the presence of circulation plasma cell-free hemoglobin.
  • Emerging approaches in the prevention of Ventilator Acquired Pneumonia.
  • Characteristics of the inflmmatory response of patients undergoing surgical procedures.
  • Acute Respiratory Distress Syndrome (ARDS).

Description of Research

In my early research career I worked at the NationalInstitutes of Health, under the supervision of my mentor Dr. Theodore Kolobow(2000-2005). We developed several new methods and medical devices to avoidaspiration and ventilator associated pneumonia: such as novel rotating beds,care of intubated patients, novel endotracheal tube designs, new methods of ventilation,and novel approach to prevent bacterial colonization of the respiratory tract.In animal models we experimented and successfully showed feasibility andefficacy of those methods. In order to test these hypotheses and other novelapproaches to prevent lung injury in mechanically ventilated patients, Dr.Robert Kacmarek and I established a Respiratory and Critical Care Research Teamin the department of Anesthesia, Critical Care and Pain Medicine at MGH. Under thementorship of Dr. Warren Zapol, I also expanded my studies on the role oftransfusion and hemolysis on hemodynamics, inflammation, endothelialdysfunction and organ dysfunction.
