In 2010, Girardi transitioned to the Harvard T.H. Chan School of Public Health as the Senior Associate Dean for Research in the Department of Global Health. In this capacity, she coordinated interdisciplinary research projects on food insecurity, nutritional epidemiology, and agricultural policy. She also served as the faculty liaison for the Harvard Institute for Quantitative Social Science, fostering the application of data analytics to policy questions.
From 2015 to 2023, Girardi held a joint appointment at Stanford University’s Center for Sustainable Systems, where she focused on integrating machine learning techniques into environmental monitoring and climate modeling. Her research has explored the use of satellite imagery and AI-driven predictive models to forecast crop yields under varying climate scenarios.
Consultancy and Advisory Work
In addition to her academic appointments, Girardi has maintained an active consultancy practice. She has advised governments in Brazil, Kenya, and Vietnam on implementing climate‑smart agriculture policies. She also collaborated with the World Bank on the “Agriculture for Development” initiative, providing evidence‑based recommendations for rural development projects.
Key Achievements and Contributions
Scientific Contributions
Girardi's scientific contributions span ecological modeling, agricultural economics, and public health. Her research on integrated pest management has been cited over 1,200 times and has informed the development of regional pesticide regulations. She pioneered the application of Bayesian hierarchical models to assess the resilience of smallholder farms to climatic shocks, a methodological innovation that has been adopted by researchers worldwide.
In the realm of data science, Girardi contributed to the creation of the “Crop Yield Prediction Atlas,” a global database that integrates climate, soil, and management data to generate high‑resolution yield forecasts. This resource has been used by policymakers to design targeted interventions during drought periods.
