Philip R. Christensen

Philip Christensen focuses on the composition, physical properties and processes, and morphology of planetary surfaces, with an emphasis on Mars and the Earth. A major element of his research has been the design and development of spacecraft infrared remote sensing instruments. His research uses infrared spectroscopy, radiometry, laboratory spectroscopic measurements, field observations, and numerical modeling, in a wide range of field sites and these tools are used to study environmental and urban development problems on Earth.
