Summary
The main focus of my current research is to extend existing deterministic and individual-based mathematical models that can inform malaria eradication strategies - how, where and when should resources be invested to most effectively reduce the global case burden and eventually eradicate Plasmodium parasites?
I also work on determining the cost-effectiveness of the recently recommended RTS,S/AS01 and R21/Matrix-M malaria vaccines, relative to scale-up of existing interventions such as insecticide-treated nets and seasonal malaria chemoprevention.
Prior to my post-doc I worked on HIV, sickle cell disease, Burkitt’s lymphoma, cervical cancer, and the RTS,S malaria vaccine. I have spent time living abroad in Kenya and Malawi, working with the U.S. National Cancer Institute’s Center for Global Health, national Ministries of Health, and other academic partners. I also serve as an epidemiology consultant for the Pan African Academy of Christian Surgeons (PAACS) and a member of the African Esophageal Cancer Consortium (AfrECC).
