Dr. Lai’s research has been focused primarily on investigating pathogenesis and development of alternative therapies for effective treatment of cardiopulmonary diseases, with the particular emphasis of metabolic syndrome, pulmonary hypertension, and heart failure with preserved ejection fraction (PH-HFpEF). She has made several important contributions to the field of pulmonary hypertension research, which include publishing research articles on 1) the effects and mechanisms of nitrite and metformin in a newly developed rat model of PH-HFpEF; 2) establishing mouse model of PH-HFpEF; 3) developing tools for rapid and accurate measurement of pulmonary vascular remodeling; and 4) identifying candidate genes associated with high-fat diet-induced pulmonary hypertension with a genome-wide association study.
Currently, much of her effort is focused on unraveling the role of sirtuin-3 (SIRT3) in skeletal muscle and its modulation of endocrine signaling pathways in PH-HFpEF.
Additionally, Dr. Lai studies effect of Remodulin (with Dr. Mark Gladwin; University of Pittsburgh), effect of Rapamycin (with Dr. Elena Goncharova; University of Pittsburgh), exercise effects (with Dr. Tim Lahm; Indiana University School of Medicine), and the role of NAMPT (with Dr. Roberto Machado; Indiana University School of Medicine) in PH-HFpEF.
