Liberty Cantrell
MSc BSc
Medical Statistician & DPhil Student
Liberty joined the Oxford Vaccine Group in 2021 after graduating from the University of Nottingham with a BSc in Mathematics and an MSc in Statistics. Since joining the team she has worked across a variety of research areas including COVID-19, pertussis and group B streptococcus (GBS).
Liberty started her DPhil in 2023 studying correlates of protection for vaccines against GBS. During this work, she is investigating antibody levels associated with a reduced risk of infant disease using case-control data from countries across Europe and Africa. She has also been conducting simulation studies to investigate the impact of the choice of analysis method on the results.
Her research interests include vaccinations during pregnancy and correlates of protection.
