I completed my BSc in Physiology at McGill University in 2009 and came to the London School of Hygiene and Tropical Medicine in 2012 to study the MSc Control of Infectious Diseases.

I joined the School as a staff member in October 2013, initially working at the MARCH Centre on various neonatal health projects. 

Currently, I am with the TB Modelling Group where I support the development of TIME Impact, a modelling tool to guide in-country policy making.

I am also responsible for providing epidemiological and mathematical modelling support to National TB Control Programmes to guide discussions around policy development and implementation.

Through dialogue with the country and the Global Fund, I model interventions from the National Strategic Plan in TIME in order to generate short and long-term estimates of epidemiological impact at the national level.

I lead or assist on practical sessions for Modelling and the Dynamics of Infectious Diseases as well as Epidemiology and Control for Communicable Diseases.


My main interests include infectious disease modelling to directly support country-level policy making.

I’m also interested in the epidemiology and impact of control measures for air-borne and respiratory infections, with a particular focus on tuberculosis and vaccine-preventable diseases.

Specific interventions of interest include strategies to maximise case finding, particularly in groups at high risk for TB.
