I am an epidemiologist with a background in disease control and research in humanitarian crises. I am interested in the control of cholera and other epidemic diseases, public health and surveillance in crises, spatial epidemiology, and epidemiology as used for decision-making. I also work on noncommunicable diseases and community health.

Previously (2011-2018), I was the lead epidemiologist for the International Rescue Committee (IRC), supporting humanitarian programmes worldwide. I have a Masters of Health Science from Johns Hopkins School of Public Health and was an FETP fellow with the Canadian Field Epidemiology Program of the Public Health Agency of Canada. I continue to work with IRC, the World Health Organization, and humanitarian organizations.

I am pursuing a PhD supervised by Francesco Checchi and John Edmunds where I focus on the mathematical modelling and evaluation of targeted interventions for cholera outbreaks (see doi.org/10.1016/S1473-3099(20)30479-5). The work is generously supported by a Doctoral Foreign Study Award from the Canadian Institutes of Health Research.
