Luisa recently finished her PhD in Biomedical Sciences at the ISPM where she has been since 2011. The topic of her thesis was mathematical modelling in HIV and Hepatitis C. She used mathematical models to simulate disease progression and estimate the impact of public health interventions on health outcomes. Her projects included the development of an individual based model of pediatric HIV to estimate the impact of different strategies to monitor children on antiretroviral therapy; and a hepatitis C virus transmission model to evaluate the effect of behavioural and treatment interventions on the spread of this virus among HIV-positive men who have sex with men. Previously, Luisa studied physics with a focus on theoretical physics and applied mathematics specializing in numeric methods at the National University of Colombia in Bogotá. Luisa is very interested in mathematical modelling of infectious diseases and Monte Carlo simulations of dynamic systems in nature. Currently, Luisa is working at the ISPM on mathematical modelling and molecular epidemiology of hepatitis C virus transmission among people living with HIV.
