Department: PREC UNIC ME

Statistics, descriptive analysis, regression models, logistic regression, multilevel regression models, survival analysis, Cox regression (proportional hazards models).

Sara Tous received her degree in statistics in 2001 from the Universitat Politècnica de Catalunya, Barcelona. From 2001 to 2003, she was working for the Catalan Centre of Innovation and Business Development as a data manager for the Department of Quality Control (Catalonian Government). In 2005, she started working at the Catalan Institute of Oncology (ICO). She received her specialisation in sciences and techniques in statistics in 2008 from the Universitat Politècnica de Catalunya, Barcelona and over the last 10 years, Sara has been involved in research of statistical regression models to study the relationship between anogenital and head and neck preneoplastic lesions and cancers and HPV infection in UNIC. She is a member of different groups (AGAUR, HPV VVAPO, RIS HPVTT) supporting research of the relationship between HPV and genital and head and neck preneoplastic lesions and cancers.
