Overview

  • Dr. Szul's broad research background and training has been rooted in membrane trafficking and molecular mechanisms that regulate the delivery of proteins to their cellular destination. Since his transition to the Division of Pulmonary, Allergy, and Critical Care Medicine, his research interests have evolved into two overlapping fields; first: to understand the mechanisms of secretion of key enzymes involved in chronic lung inflammation (MMP9, PE, LTA4H); and secondly: to map out the role that single nucleotide polymorphism (SNP) in combination with conventional cigarettes/e-cigarettes plays on expression and activity of these enzymes.
