Fields of interest:
Geophysics; Remote Sensing; Population and Environment. Prior to 1992, the surfaces of Venus and Mars had been mapped in greater detail than the surface of Earth. Recent advances in remote sensing now provide us with detailed maps of seafloor structure and synoptic views of Earth's land surface. Remotely sensed observations also allow us to quantify the spatial and temporal dynamics of the Earth system. Quantifying these dynamics is the first step toward understanding them. Geophysics provides powerful tools and concepts that can be used to quantify and understand the dynamics of the Earth system. My research interests focus on the application of geophysics, remote sensing and spatio-temporal analysis to the study of the Earth system. Remotely sensed observations provide a necessary synoptic complement to field measurements. Similarly, field validation is necessary to calibrate remotely sensed measurements. Field validation also provides justification for travel. Since coming to Columbia in 1993, My interest in the Earth system has expanded to include its biospheric components. Recognition that the tools and concepts of geophysics can be applied to a wider range of questions has resulted in a number of cross-disciplinary collaborations ranging from tropical deforestation monitoring to urban growth mapping. My current research interests center on the use of satellite remote sensing to quantify changes in Earth's surface and the causes and consequences of these changes. These interests have recently taken me to the Ganges-Brahmaputra Delta, the North Fiji Basin, the Ethiopian highlands, the Galapagos Archipelago, the Gobi Desert, the Belize River Basin and the Peruvian Andes. Some of my projects include:
