I am broadly interested in the conservation of Earth's biological diversity in the face of many interrelated threats, such as climate change, altered disturbance regimes, and land-use conversion. My research interests are in using remote sensing, geospatial technology, and machine learning to map and monitor our changing coupled human and natural systems at multiple spatial and temporal scales, with the goal to deepen our understanding the drivers of change and to find practical solutions.
I am currently working locally in California with wildfire science and citizen science-driven biodiversity applications, including sensors on unoccupied aerial systems (e.g., drones) to satellites. I also have a new international research project in South Africa focused on understanding patterns of animal diversity from ground-based acoustic analysis and spatial information from advanced hyperspectral and lidar remote sensing technology.
