Dr Shaun Pennington

Lecturer in Infection and Immunity

Shaun was awarded a PhD in Infection and Immunity from the University of Liverpool in 2017. His interests lie in human immunity and the interplay between host and pathogen.


Shaun utilises controlled human infection as well as advanced ex vivo models for studies investigating disease pathogenesis and host immune defence. His activities support a broad translational research portfolio towards delivery of new vaccines and novel therapeutic strategies to the clinic.


Shaun currently lectures and leads teaching tutorials on the topics of ‘Pharmacodynamics’ and the ‘Immunology of Tropical Disease’ at LSTM.

Shaun is a member of the Royal Society of Biology.
