I am working with the Tropical Ecology Assessment and Monitoring (TEAM) Network on a project investigating the effects of climate change and land use and cover change around tropical protected areas on biodiversity. We are linking species data from plot and camera trap monitoring to satellite observations to study linkages between land cover change and biodiversity.
Below are several ongoing projects related to TEAM.
teamlucc is an R package to support the preprocessing and classification of satellite imagery for biodiversity monitoring and land cover change modeling.
glcm is an R package for calculating image textures measures derived from grey-level co-occurrence matrices (GLCM).
An open-source agent-based model toolkit written in Python.
ChitwanABM is an agent-based model of the western Chitwan Valley, Nepal, used to explore connections between population and environment.
Land Use and Cover Change in the Chitwan Valley, Nepal
Worked with Dr. Li An on an NSF PIRE project exploring human-environment interactions in the Western Chitwan Valley, Nepal. In order to better incorporate feedbacks between fertility and environmental change, we constructed an agent-based model of population at the individual, household, and neighborhood levels, and modeled interactions between demographic change and land use change. Our research using a spatially explicit agent-based model allows a better representation of spatial variation in the determinants of land use, as well as of the spatial distribution of land use change, which may be an important determinant of habitat quality in the forest areas surrounding the study area.
Health, Poverty, and Place in Accra, Ghana
I was also a part of a team working on a NIH funded project in Accra, Ghana “Health, Poverty, and Place in Accra, Ghana”, (PI Dr. John Weeks), to explore relationships between neighborhood context and health outcomes.
Rural Energy Infrastructure
Studied the impact of population distribution in rural areas on the costs of infrastructure investment. With Dr. Vijay Modi of Columbia University.
Climate System Dynamics
Constructed an agent-based model examining dynamics of coupled human-climate system over long timescales. With Dr. Brad Werner of Scripps Institution of Oceanography.
