Dr Ruy M. Ribeiro got his Ph.D. in Mathematical Biology at the University of Oxford, UK. He then joined Los Alamos National Laboratory (LANL) in 2000, as a Postdoctoral Researcher, later becoming a staff scientist working on viral and immune system dynamics. His main research interests are the pathogenesis of infections, and the use of quantitative modeling tools to gain insight into viral and immune system dynamics. His work has always entailed close collaborations with experimental researchers to develop proper statistical and dynamic models to analyze experimental data. His modeling work spans multiple scales from the intracellular (eg. a model of the molecular details of HCV infection) to the epidemiological (including HIV and influenza epidemics). He was Professor of Statistics at the Medical School of the University of Lisbon, while on leave from LANL, between 2017 and 2020. Ruy Ribeiro has over 140 peer-reviewed papers in this area, and he is/was the PI of several research projects funded by the National Institutes of Health, the European Union, and the Department of Energy.
