LAURA J. CROSSEY

Ph.D., University of Wyoming, 1985. (Professor) (505) 277-5349 lcrossey@unm.edu

Research and Academic Interests:

Sedimentary Geochemistry. Research interests in clastic diagenesis, aqueous and organic geochemistry, and geomicrobiology, with emphasis on interaction of organic and inorganic constituents of sedimentary rocks during progressive burial. Research approach includes field examination of modern early diagenetic environments (biogeochemistry of water and sediments) as well as core and outcrop evaluations of sandstone and shale diagenesis. Prospective graduate students can read the letter linked here. To find out more about the variety of research projects, check out the Diagenesis Research Pages and the Hydrogeoecology Research Pages. For class links, see below.
