Dr Charlotte Hammer
Everitt Butterfield Research Fellow at Downing College, epidemiologist
Dr Charlotte Hammer is an applied infectious diseases epidemiologist. She completed her PhD in the Health Protection Research Unit for Emergency Preparedness and Response under the supervision of Professor Paul Hunter on outbreak risks in humanitarian emergencies.
