Biography
I am passionate about the use of statistics and geospatial sciences in addressing problems in environmental sciences.
Expertise Summary
I am interested in understanding how uncertainties in the spatial prediction of soil and crop micronutrients can be communicated effectively to diverse stakeholder groups (e.g., agronomists and nutritionists), and how stakeholder groups interpret the information when making decisions to address micronutrient deficiencies in sub-Saharan Africa.
Research Summary
In my current role, I am a data scientist contributing to harmonized scripting approaches for data cleaning, e.g., identification of outliers, for micronutrient surveys conducted at the national… read more

Current Research
In my current role, I am a data scientist contributing to harmonized scripting approaches for data cleaning, e.g., identification of outliers, for micronutrient surveys conducted at the national scale for Malawi, Ethiopia, and India. I also undertake mathematical and/or statistical modelling of survey datasets for nutritional assessments for population micronutrient supply, using harmonized scripts.
