Dr. Nianogo is an Assistant Professor in the department of Epidemiology at the UCLA Fielding School of Public Health. He is a general medicine physician-scientist and epidemiologist. The goal of his research lab, CiPreme (Causal Inference for Preventive Medicine and Epidemiology) is to develop and utilize innovative and rigorous epidemiologic, econometric and causal inference methods, as well as computational modeling and simulation tools for investigating the impact of lifestyle, metabolic and social interventions in preventing chronic diseases and translating such evidence into effective clinical, public health and policy interventions. To this end, Dr. Nianogo has developed interests and expertise that are both methodological and substantive in nature. Methodologically, his work has involved the application of advanced epidemiologic tools including: (1) population impact assessment methods (e.g. g-computation, population attributable fraction), (2) longitudinal analytics methods (e.g. causal mediation analysis, causal survival analysis), (3) quasi-experiments and instrument-based methods (e.g. difference-in-difference, synthetic control methods) and (4) predictive modeling and simulation tools (e.g. machine learning, microsimulation). Substantively, Dr. Nianogo’s work has focused on the prevention and treatment of chronic diseases including cardiovascular diseases (CVD), diabetes, obesity, cancer, Alzheimer's diseases and related dementias as well as the reduction of health disparities.
Dr. Nianogo received his MD in general medicine from the Université de Ouagadougou in Burkina Faso, his MPH in Community Health Sciences at UCLA, his PhD in Epidemiology at UCLA and completed a post-doctoral fellowship in systems science modeling at UCLA.
