My research lies in preventive medicine, primarily focusing on cancer and vaccine epidemiology. I use methodologies that employ observational designs leveraging electronic health records as well as modeling techniques to support preventive programs. The research output is pivotal in advancing the global effort in controlling human papillomavirus (HPV)-related diseases, particularly aligning with the WHO's global strategy to eliminate cervical cancer as a public health problem.

The main areas of my research contain:
1) An extensive evaluation of HPV vaccination in Sweden, encompassing both girls-only and gender-neutral vaccination programs. This includes studying the vaccine's effectiveness and its impact on reducing HPV-related diseases in the population.
2) Investigating the relationship between HPV, HPV vaccination, and reproductive outcomes.
3) Developing risk prediction models for cervical diseases, which incorporate screening trajectories and other risk factors.
4) Forecast the impact of HPV vaccination on the six types of HPV-associated cancers
