Lung development; bronchopulmonary dysplasia; pulmonary hypertension; asthma; pulmonary fibrosis
Timothy LeCras, PhD, investigates the causes of chronic lung diseases, including pulmonary hypertension, bronchopulmonary dysplasia, pulmonary fibrosis, and asthma. The goal of his laboratory is to use this knowledge to identify therapeutic targets and preventative measures. Our efforts are aided by very productive collaborations with other groups at Cincinnati Children's as well as other groups in the U.S.
Postdoctoral fellow: University of Virginia, Charlottesville, VA, 1993-1996.

PhD: University of Cambridge, UK, 1988-1992.

BSc: Biochemistry, Brunel University, London, UK, 1983-1987.
