David “David S. Lopez” Lopez, DrPH, M.P.H., M.S. Titles and Appointments Associate Professor Schools School of Public Health Departments Public Health | Harold C. Simmons Comprehensive Cancer Center Biography Download Curriculum Vitae My research program is at the intersection of cancer epidemiology, pharmacoepidemiology, causal inference, and advanced epidemiologic methods, with a particular focus on underserved and understudied populations. I apply rigorous methodological approaches, including target trial emulation, to investigate the etiology and progression of obesity-related cancers and chronic diseases among cancer survivors. My research focuses on the impact of obesity, and its treatments, including anti-obesity medications (e.g., glucagon-like peptide-1 receptor agonist- GLP-1 RA), repurposed medications (e.g., metformin, statins and testosterone replacement therapy), and bariatric surgery on cancer risk, progression and survivorship outcomes. I have led studies leveraging large-scale real-world data sources, including SEER-Medicare, electronic health records, and claims databases, to advance understanding of obesity-, hormonal-, and cardiometabolic-related cancer outcomes. I have established a highly productive collaborative research program that has generated multiple high-impact publications and novel evidence on GLP-1 receptor agonists, bariatric surgery, and obesity-related cancers.
