Research & Publications

Research Summary

Dr. Kolb’s research interest is on disorders of the pulmonary circulation, with a primary focus on the function of the right ventricle in chronic pulmonary hypertension. He conducts laboratory research aimed at understanding basic mechanisms of right ventricular adaptation to this life threatening condition, focused primarily on adaptations of the vascular supply to the right ventricle.

He also collaborates with investigators from multiple Departments on clinical research projects focused on the physiology, assessment, and management of various forms of pulmonary hypertension, including those complicating acute respiratory failure and the acute respiratory distress syndrome. Dr. Kolb has over 40 publications, most of which address problems in pulmonary hypertension and the pulmonary circulation.
