About Me

I am an environmental geographer interested in how global environmental change is affecting human well-being. Before academia, I lived all over the world - from Mali to Alaska to the Philippines - working at the intersection of policy and research. Now, I work with large datasets at global scales using data science methods, but with my research questions and hypotheses deeply informed by my experiences in the field and in the policy sector.

In my research, I work with “big micro-data”: surveys conducted at individual and household levels, combined and harmonized to give a global, high-resolution picture of human well-being. Combining these data with information on prevailing ecological, agricultural, and climatological conditions, I use machine learning methods to better understand how the environment affects human well-being. I’m particularly interested in understanding which populations are most vulnerable to environmental change and which policy interventions could lead to the greatest improvements in well-being, as well as using scenarios to attribute well-being to historical change and forecast what the future might look like.

Developing a global indicator for Aichi Target 1 by merging online data sources to measure biodiversity awareness and engagement

Due to the importance of public support in fostering positive outcomes for biodiversity, Aichi Biodiversity Target 1 aims to increase public awareness of the value of biodiversity and actions that help to conserve it. However, indicators for this critical target have historically relied on public-opinion surveys that are time-consuming, geographically restricted, and expensive. Here, we present an alternative approach based on tracking the use of biodiversity-related keywords in 31 different languages in online newspapers, social media, and internet searches to monitor Aichi Target 1 in real-time, at a global scale, and at relatively low cost. By implementing the indicator, we show global patterns associated with spatio-temporal variability in public engagement with biodiversity topics, such as a clear drop in conversations around weekends and biodiversity-related topic congruence across culturally similar countries. Highly divergent scores across platforms for each country highlight the importance of sourcing information from multiple data streams. The data behind this global indicator is visualized and publicly available at BiodiversityEngagementIndicator.com and can be used by countries party to the Convention on Biological Diversity (CBD) to report on their progress towards meeting Aichi Target 1 to the Secretariat. Continued and expanded monitoring using this indicator will provide further insights for better targeting of public awareness campaigns.
