Bio

I have been working at the Bruno Kessler Foundation in Trento, Italy, since my PhD in Information and Communication Technology (University of Trento, 2011). Previously, I had received a MSc in Biomedical Engineering (University of Pisa, 2006). During my PhD, I have spent 6 months at the Denise Kirschner’s lab at the University of Michigan Medical School. My main research interest is infectious disease modeling with a focus on public health applications, i.e. risk assessment, outbreak investigation, and the evaluation of the effectiveness of interventions. I am also interested in the epidemiological impact of immunological dynamics. Diseases I have studied include tuberculosis, varicella and herpes zoster, meningococcal meningitis, human papillomavirus, hepatitis A, mosquito-borne infections, antimicrobial resistant pathogens and SARS-CoV-2. I am currently Editorial Board Member at BMC Public Health.
