Dr Ganna Rozhnova is an Assistant Professor in Infectious Disease Modeling at the Julius Center for Health Sciences and Primary Care and an affiliated researcher at the BioISI—Biosystems & Integrative Sciences Institute in Portugal. Her research centers on the application of infectious disease modeling to answer questions and support evidence-based policymaking in public health. She is interested in the emergence, evolution and spatio-temporal dynamics of infectious diseases on different scales (e.g., host, hospital or population) as well as in the evaluation of the impact of interventions on disease transmission. Her most recent research aims to address the prospects of HIV elimination, the impact of promising HIV cure strategies on HIV transmission, and (post-)pandemic dynamics of SARS-CoV-2. Other applications include influenza, CMV and childhood infections.

Dr Rozhnova is a recipient of highly competitive awards (PhD and postdoctoral fellowships from the Portuguese Foundation for Science and Technology, Award “Stimulus for Research” from Calouste Gulbenkian Foundation), institutional excellence programs (Research Career Development Program) and grants (PI on six projects with the total budget of €730,000 and co-Applicant on two projects with the total budget of €220,000). She held official appointments as an invited visiting scientist at the University of California (Santa Barbara, USA), the Newton Institute for Mathematical Sciences (Cambridge, UK), the Gladstone Institute of Immunology and Virology (San Francisco, USA), and the MRC Biostatistics Unit (Cambridge, UK). The main funders of her current research are Aidsfonds, FCT and ZonMw. 

Side Activities

Dr Rozhnova is an Editorial Board Member for Communications Medicine (Nature portfolio journal) and a member of several professional organizations (European Women in Mathematics, Institute of Physics, Society for Industrial and Applied Mathematics).
