  Clinical Interests  

Special interest in General Thoracic Surgery problems relating to lungs, mediastinum and esophagus. Secondary interest: General Surgery, Intensive Care, Trauma. Strong believer in minimally invasive surgical approaches to thoracic pathology including Video Assisted Thoracoscopic Surgery (VATS). Also strong advocate of multidisciplinary approach to evaluation and treatment of lung cancer.

  Educational Interests  

I strongly believe that it is our professional duty to pass on wisdom and experience to the next generation of surgeons. Interacting with surgery residents and seeing them grow from timid interns to well educated, technically skilled and overall competent chief residents is the most rewarding aspect of being in academic practice. I am especially interested in the overall organization of the residency to maximize the residents learning experience and the latest educational and evaluation methods such as OSCE's, Simulation labs and incorporation of the six core competencies into the curriculum and clinical teaching.
