In 2005 Ghani was appointed to the faculty at the
London School of Hygiene & Tropical Medicine. Here she became interested in malaria, particularly the disease's complexity, and the need to understand many aspects of science and society to better control it. She develops mathematical models that can better describe the transmission dynamics of malaria, to visualise how it impacts both humans and mosquitoes, and use this insight to fight the disease. Ghani serves on the malaria policy advisory committee of the
World Health Organization. In 2017 Ghani was elected to the
Academy of Medical Sciences. Through her understanding of infectious diseases, Ghani looks to better inform public health interventions. In 2020, during the
COVID-19 pandemic, Ghani reported self-isolation, home quarantine and social distancing could limit the number of UK deaths caused by the
coronavirus to 20,000. She worked with
Neil Ferguson to show that during the course of the pandemic, the
National Health Service would become overwhelmed by the number of cases. == Awards and honours ==
