My research focuses on micronutrient dynamics in food and agriculture systems, and I lead the LSHTM contribution to two projects in this area, both funded by the Bill & Melinda Gates Foundation:

I am co-lead investigator on the GeoNutrition project. GeoNutrition aims to inform strategies to alleviate micronutrient deficiencies (MNDs) primarily in Ethiopia and Malawi, through (1) improving baseline estimates of MNDs, (2) identifying and understanding factors underlying MNDs, and (3) testing interventions to alleviate MNDs. Through this project, I have led the AHHA trial in Malawi, to test whether selenium deficiency can be effectively alleviated in a rural Malawi population through consumption of maize enriched with selenium fertilisers.

I lead LSHTM's contribution to the MAPS project, which aims to develop an online tool to improve access to data on micronutrient status and the potential effectiveness of different interventions in sub-Saharan Africa.

I also work on the BiZiFED project - examining the effectiveness and acceptability of zinc biofortified wheat for alleviating zinc deficiency in Pakistan.

Much of my work involves integrating and analysing large-scale spatial datasets. Sometimes my work is field-based, including implemention of the AHHA trial and, in previous projects, conducting agronomic trials and soil/crop sampling. 

I co-developed the Diet Dimensions game, a multiplayer social game that fosters cross-disciplinary collaboration and learning.
