I have been working on yellow fever (YF) related research since my MSc in Epidemiology at Imperial College London in 2015.

Following this I stayed on in the department, developing work on the influence of climate and seasonality on transmission in Africa. My research focus quickly branched out to encompass further YF activities such as outbreak response during the 2015-2016 outbreak in Angola and the Democratic Republic of the Congo, as well as Nigeria 2017-2018.

Additionally I have developed and maintain a web-based tool for visualizing YF vaccination coverage across Africa for 1950-2050, which has garnered substantial interest and use from the World Health Organization (WHO) and other relevant parties in public health policy.

Since January 2017 I have been undertaking a PhD under the supervision of Dr Tini Garske and Professor Neil Ferguson investigating the influence of climate and the environment on YF in Latin America, including work on the role of non-human primates.
