Professional Summary:

I am an acute care surgeon board-certified in both surgery and surgical critical care. The most important part of my job is providing compassionate care to my patients, who are often acutely injured and/or critically ill. I have a deep awareness of, and empathy for my patients’ suffering, and I do my best to alleviate it. My clinical focus is in trauma, critical care and emergency general surgery. I also perform laparoscopic surgery, gastrointestinal surgery (small bowel, colorectal and biliary), complex hernia surgery, as well as endoscopy and wound care.

My research is focused on improving care for injured and critically ill patients, including topics in gut-origin bacterial translocation, aspiration and acute respiratory distress syndrome (ARDS), damage control resuscitation and imaging in trauma. I was a co-investigator on NIH-funded grants for evaluation of aspiration biomarkers in trauma and surgery, as well as on an SIS multicenter study on duration of antibiotics for abdominal infection. I encourage medical students and residents to approach me for collaborative research opportunities. The research experience will enable them to develop critical thinking and help shape their practice of medicine. I have mentored numerous surgical residents and medical students in research, which has led to them receiving national research awards.

I have a passion for teaching medical students and residents. I find satisfaction in sharing my knowledge and experience with those in the training phase of their careers. In return, their questions help me stay current in my field and ultimately help me render the best care to my patients. I am the course director of the elective internship in trauma. I also give lectures on traumatology to medical students. As a surgeon, role model and educator, I have inspired many medical students to pursue surgery as a career.
