My research examines how economic, political, and environmental disturbances affect food security, nutrition, and health, and how the systems designed to measure and respond to these crises perform in practice. Using causal inference methods, I study both the direct welfare effects of shocks on vulnerable populations and the downstream effects of classification systems, such as IPC, on where aid actually flows, work that treats humanitarian data infrastructure itself as an object of empirical scrutiny. I also develop machine learning and NLP pipelines for triangulating disparate, low-quality data sources into more timely and accurate vulnerability assessments.
I completed my Ph.D. in Applied Economics at the University of Illinois Urbana‑Champaign. [View Full Curriculum Vitae →]

International humanitarian aid is a critical tool for mitigating acute food security crises. However, its effectiveness in responding to institutionalized crisis alerts, such as the Integrated Food Security Phase Classification (IPC), remains empirically understudied at the subnational level. This paper constructs a novel dataset of geocoded aid flows in Afghanistan and uses a staggered difference-in-differences design to estimate the causal impact of an escalation to a severe food security emergency. The analysis reveals that while an alert triggers a rapid and statistically significant increase in aid, the response is both transitory, fading quickly after the initial months, and insufficient, falling substantially short of estimated basic needs.
Evaluating early childhood nutrition shocks and long-term development metrics
This study examines the causal linkage between local market prices of nutritional staples—specifically dairy—during critical early-life development windows and child stunting outcomes across urban and rural Zambia, utilizing comprehensive household survey and market price panel data.
Empirical investigation into global acute hunger monitoring systems and underreporting
An empirical investigation into global acute hunger monitoring systems, revealing systematic undercounts in acute food insecurity assessments and highlighting structural gaps in global crisis targeting.
Evaluating internal consistency and methodological rigor across crisis assessment frameworks
This paper evaluates internal consistency and methodological rigor across global crisis assessment frameworks, analyzing divergence across multiple indicators and institutional analytical workflows.
Guiding principles for ethical and interpretable humanitarian forecasting models
Formulates best practices and guiding principles for deploying machine learning models in humanitarian food security forecasting, emphasizing transparency, interpretability, and decision-maker trust.
Learning, Assessing, Calibrating, and Integrating AI/ML model outputs
Developed the Learning, Assessing, Calibrating, and Integrating (LACI) framework to evaluate AI, ML, and statistical model outputs for IPC integration. Designed operational tools (Learn and Assess Cards) to conduct technical screening, define context-specific limitations, and map outputs to IPC workflows.
Empirical evaluation across 26 countries and 780,000+ households
This project presents a data-driven approach to optimize classification thresholds used in food security monitoring systems. By evaluating pairwise concordance and agreement metrics across multiple indicators, the method seeks to enhance consistency and alignment between measurement tools across 26 countries.
Real-time NLP risk monitoring system extracting early warning signals
Leveraging advances in natural language processing—including transformer-based sentiment analysis and unsupervised topic modeling (BERTopic)—this system processes scraped news articles through a pipeline of geoparsing, thematic classification, and temporal aggregation, aligning results with the IPC framework.
Conducting advanced research at the intersection of climate change, conflict, displacement, and health in fragile settings, developing predictive models and rigorous evaluation frameworks for humanitarian response.
Designed and executed econometric impact evaluations for rural development projects, analyzing household microdata to measure agricultural productivity and income gains.
Co-authored technical diagnostics and spatial mapping reports on poultry hotspots in Tanzania and agricultural dietary diversity in Viet Nam.
Before starting my doctoral studies, I worked for three years as a Project & Training Officer on an agricultural development project in Kilosa District, Tanzania (2015–2017). Working closely with smallholder farmers, I conducted field-based assessments and implemented climate-resilient agricultural practices—an operational foundation that deeply informs my empirical research today. Below is a visual gallery of my fieldwork and analytical research pipelines.
