BIO
My research addresses the emergence, evolution and transmission of viruses with epidemic and pandemic potential, with particular focus on arboviruses and viral haemorrhagic fevers. I lead multidisciplinary research that integrates molecular virology, vector biology and genomics to investigate virus–host and virus–vector interactions, supporting risk assessment, surveillance and outbreak preparedness.
I lead experimental studies on mosquito-borne orthobunyaviruses such as Tahyna virus, alongside broader work on viruses within the class Bunyaviricetes, including nairoviruses such as Crimean-Congo haemorrhagic fever virus and Hazara virus, and phleboviruses such as Rift Valley fever virus. My research also extends to other medically important arboviruses, including alphaviruses and flaviviruses, and to emerging zoonotic pathogens such as Nipah virus, as well as New World arenaviruses, important rodent-borne agents of viral haemorrhagic fever in the Americas.
Alongside my academic research, I contribute to applied public health virology through collaborative work with the UK Health Security Agency, including laboratory-based studies on emerging and high-consequence viruses at Porton Down.
I lead a research programme that includes supervision of postgraduate students and contributes to international capacity building in virology through collaborations with partners in Africa, Asia, Europe and Latin America, including links with the Institute of Tropical Medicine (NEKKEN) at Nagasaki University.
My laboratory will be offering an MRes project from September 2026 as part of the London School of Hygiene & Tropical Medicine MRes programme in Infectious & Tropical Diseases (see: https://www.lshtm.ac.uk/study/courses/masters-degrees/mres-infectious-tropical-diseases#mres-projects).
MRes project: Non-infectious tools for differentiating Chikungunya and other alphaviruses
This project will develop safe, non-infectious diagnostic approaches to distinguish closely related alphaviruses, including Chikungunya virus. The work will combine assay design using synthetic RNA standards, serological assays based on reporter viruses, and integration into a practical diagnostic framework for surveillance. The majority of laboratory work will be based at UKHSA Porton Down.
