The role of matrix metalloproteases in disease and the inhibition of these enzymes as potential therapy in destructive lung diseases.



Research Activities

The major goal of my research program is to develop insight into lung physiology and pathology through understanding the mechanisms altering lung injury and repair and translating these findings into practical clinical solutions. My research studies mainly focus on the role of matrix metalloproteinases (MMP) in normal physiology and in human disease integrating both in vitro and in vivo approaches. My laboratory is also uniquely situated to characterize the molecular changes in the study of smoke-induced injury and disease so as to identify potential therapeutic targets for smoke induced disease processes.
