Overview
My research program focuses on identifying mechanisms of mitochondrial dysregulation by environmental toxicants that correlate with increases in mortality of chronic lung diseases, such as pulmonary fibrosis and pulmonary hypertension. An additional aspect of this research is to identify whether platelets can be used as biosensors of metabolic perturbation and surrogates for lung tissue. This research integrates biochemical techniques with ultra-high-resolution metabolomics for metabolic pathway detection, mitochondrial bioenergetics for metabolic flux studies, chemical profiling for toxicological surveillance, heavy metal quantitation, and lastly, integrating these data using systems biology approaches with novel bioinformatics tools.
