Academic Appointments

  • Assistant Professor of Pediatrics at CUMC

Administrative Titles

  • Wellness Champion for the Division of Pediatric Critical Care Medicine

I was trained both in General Surgery as well as as in General Pediatrics and Pediatric Critical Care Medicine. My clinical experience encompasses over 30 years as a Pediatric Critical Care Physician and presently spend time in Pediatric Neuro-Intensive Care Unit as an Attending Physician. I also attend on critically ill children in general pediatric critical care unit as well as in Pediatric Cardiac Care Unit. Our patient population consists of critically ill neuro, cardiac, pulmonary, transplant, trauma, cancer, Genetic Metabolic patients with complex medical issues. I'm trained in a wide variety of supportive therapy such as High Frequency Osciilation, Renal Replacement Therapy, Extracorporeal Membrane Oxygenation, the use of ultrasound in accessing blood vessels for vascular access. I was trained in the use of Indirect Calorimeter in assessing energy needs of critically ill as well as non-critically ill children. Burn-out is an important phenomenon that afflicts physician in general and particularly physicians working in Critical area. We conducted our 1st work shop on recognizing physician burn out and train them to acquire resilience. As a champion of wellness in critical care, I plan to conduct periodic assessment of physician burn out in our faculty and fellows that are undergoing training in critical care. We have introduced both burn-out scale as well as grit scale that would track the wellness of our faculty and traines.

My research interest includes immune response following sepsis in rodent models as well as in critically ill pediatric patients. I have worked over the past 25 years studying the role of gastrointestinal associated lymphoid tissue (GALT) in sepsis and burn injury, the relation between coagulopation and inflammation in sepsis and Systemic Inflammatory Response (SIRS) and the role of aldo-ketoreductase Aldose Reductase (AR) in inducing lung injury following septic peritonitis. We have used various techniques to induce septic inflammatory response in both adult as well as rodent pups. These techniques included intra-peritoneal administration of bacteria, lipopolysachharide (LPS), and insertion of rodent fecal pellets containing bacteria into the peritoneal cavity to induce peritonitis as well as cecal ligation and puncture to induce septic peritonitis. My research included working with transgenic adult mice to understand how they differed from their wild type counterparts in their cardiovascular and pulmonary responses following septic peritonitis. In addition, I’m involved in translational research involving pediatric patients. We have investigated the role of peripheral neutrophil AR expression on the outcome in pediatric patients admitted to pediatric critical care unit in acute respiratory failure within the first 24 hours of admission. Another translational ongoing research project involves investigating the role of lymphocytes in viral lower respiratory tract infection is helping us to understand the lung adaptive immunological response following viral inflammation and contrast that with bacterial inflammation that I have studied in the past few years.

In the recent past I have developed my interest in critical care nutrition by working with PCCU nutritional support group and developed PICU enteral nutrition guidelines to be used in both Komansky and Morgan-Stanley Children’s Hospital campuses. We have introduced Indirect Calorimeter (IC) in assessing the resting energy expenditure (REE) in critically ill children which has helped us to tailor appropriately nutritional needs of critically ill children. We have extended IC use to patients admitted to pediatric floor as well as outpatients. We have undertaken outcome studies in this area.
