Work Summary

Stefano Guerra's work includes an epidemiologic study, which used a household-based approach to assess prevalence and longitudinal changes in respiratory health. Other biomarker projects include a study on molecular biomarkers of asthma and COPD from the European Community Respiratory Health Survey.

Research Interest

Stefano Guerra, MD, PhD, is a professor of Medicine, the Director of the Population Science Unit at the Asthma and Airway Disease Research Center, and a leading expert in the natural history and biomarkers of obstructive lung diseases, including asthma and chronic obstructive pulmonary disease (COPD). As principal investigator, he is engaged in the leadership and coordination of multiple studies that use bio-specimens and phenotypic information from independent epidemiological cohorts to characterize the natural history, profile the risk factors, and identify novel biomarkers of lung diseases.

The study of circulating biomarkers and their association with disease outcomes has become progressively complex due to advances in the measurement of these biomarkers through multiplex technologies. The Least Absolute Shrinkage and Selection Operator (LASSO) is a data analysis method that may be utilized for biomarker selection in these high dimensional data. However, it is unclear which LASSO-type method is preferable when considering data scenarios that may be present in serum biomarker research, such as high correlation between biomarkers, weak associations with the outcome, and sparse number of true signals. The goal of this study was to compare the LASSO to five LASSO-type methods given these scenarios.
