Research Interests Molly E. Brown, PhD

My research focuses on the nature-society interface, where environmental variability and change affects food security, nutrition outcomes, agricultural development and other aspects of society.  I use satellite remote sensing to understand environmental dynamics, and social and economic datasets that allow for exploration of the impact of these dynamics on communities at a continental scale.  I conduct research in four areas: using long term data records in vegetation and rainfall to understand environmental change, particularly in Africa; research to develop new methods for ensuring the use of new and existing satellite remote sensing in applications with societal benefit; use of satellite data with demographic and nutrition household surveys to measure the impact of environmental shocks on human health outcomes; and the development of models and methods that enable the quantification of the impact of environmental and international food price shocks on local food prices. Ongoing projects include:

  • Developing new methods to integrate remote sensing data into econometric, nutrition, and food security models to improve our understanding of the effect of weather and climate on society;
  • Exploring the use of long term records of vegetation, rainfall, soil moisture and evaporative stress in agriculture insurance programs in Africa;
  • Working with local, national and international organizations to incorporate Earth science data and models to improve hazard early warning and understand of the threats of climate change;
  • Understand the value of satellite remote sensing data in decision making communities; and
  • Engaging with decision makers across the agriculture value chain in tropical countries.

I recently have begun working with 6th Grain Corporation as their Chief Science Officer. 6th Grain is an innovative and agile digital agriculture technology company with solutions being used by leading input suppliers and other large international companies in both low and high-income country settings. 6th Grain provides high quality, actionable intelligence via mobile device that will guide focused marketing and infrastructure investments by growers and agricultural companies.
