Her early interests were in the areas of oxidative stress and musculoskeletal diseases. Her initial interest in lung disease was through studies of oxidative stress markers in COPD patients. She has been involved with the COPDGene study since 2007 when the project was funded by the National Heart, Lung and Blood Institute (NHLBI) with principal investigators, Drs. James Crapo and Edwin Silverman. As Associate Director for the study she participated in the initiation of the project and continues to be actively involved in study management and data analysis. This project provided an opportunity to oversee a 10,000 subject longitudinal cohort along with colleagues at National Jewish Health and Brigham and Women’s Hospital as well as other institutions across the US. Major research interests within the cohort have been: assessing occult disease in heavy smokers, osteoporosis and fractures, other comorbid disease in the cohort and longitudinal assessment of incident disease and mortality. She has continued to develop cohorts in chronic diseases especially seeking out opportunities to decrease diagnostic error and increase early identification of diseases like lung cancer and adrenal insufficiency. Dr. Regan also enjoys teaching and mentoring with college interns, medical students, residents, fellows and post-docs frequently engaged in summer rotations through the Crapo Lab studying oxidative stress markers in joints and adrenal tissue. She also teaches Problem-Based Learning, diagnostic skills and patient-physician communication at the University of Colorado School of Medicine to first- and second-year medical students. Discussion A major focus of my research group is the engagement with the COPDGene Study. This is an exciting cohort of smokers that was enrolled 2007-2012 to study the genetics and subtypes of COPD. We initially enrolled more than 10,000 smokers across the United States at 21 Clinical Centers. The project was funded by the NHLBI and has been re-funded twice permitting us to re-evaluate our subjects in Phase 2 (2012- 2017) and now in Phase 3 (2017 – 2022). The subjects have been extensively evaluated with spirometry, chest CT scans, blood collection and questionnaires about their symptoms and function.
