Mike Bramble

My research interests span the geological and planetary sciences, and in particular I am interested in the advancement of geological quantitative measurement and analytical techniques, and studying planetary environmental change and surface alteration. These topics converge in the remote sensing of planetary surfaces.

My research revolves around using remote sensing data for studying surface processes that transform the martian surface to help interpret the conditions of Mars' paleoclimate and paleoenvironment. I am specifically interested in studying the morphology and composition, through high resolution imaging and imaging spectroscopy, of various martian sedimentary landforms in order to determine the mechanisms involved in the formation and erosion of such bedforms. My initial work focuses on understanding and determining the processes responsible for the formation of large sedimentary deposits located in the center of martian impact craters similar to Mt. Sharp, the central mound that the Curiosity rover is currently investigating, in Gale crater.

My undergraduate research focused on the characterization of exoplanets, including their atmospheric characteristics. Now, my graduate research revolves primarily around the Martian subsurface. I am specifically interested in subsurface molecular hydrogen production, which has important implications for potential biological activity at different times in Mars' history. To understand the extent and magnitude of subsurface hydrogen production, I employ numerous facilities, including remote sensing observations from multiple Martian satellites, Martian meteorite mineralogical and elemental abundances, Mars rover data, and Earth analogue sites that are similar to Mars in specific capacities. Combined, these resources give us as close to a comprehensive understanding of Mars as is possible today.

I am interested in the mineralogy of the terrestrial planets and how small scale processes can help interpret large scale phenomena. In the past I have worked on grain size implications for paleostress conditions and have used phase associations in E-chondrites as a proxy for Mercury's surface mineralogy. Currently, my work aims toward interpreting Mars' past climate history through study of minerals formed by aqueous alteration.
