My current research focuses on the role of microbes in the precipitation of carbonate minerals in rocks and other interesting places. I have most recently been looking at the role of nannobacteria in the precipitation of minerals in human arterial plaque. I'm also finishing up a project on characterization of the biotic component, chemistry, and travertine deposits in hot springs near Viterbo, Italy and a series of controlled precipitation experiments to determine the role of organic molecules and biofilms in mineral formation.

My favorite research involves carbonate petrography. I've long been alternately intrigued, confounded, amazed, annoyed, and befuddled by peloidal to clotted textures in carbonate rocks. This has lead me into studies of the origin and nature of leopard rock from the Sacramento Mountains, New Mexico, studies of microbial micrite in the lower Capitan Formation, and a study of microbial stromatolites and ooids from Pleistocene lake deposits in the Texas panhandle. In the future I would like to take a detailed look at the role of microbial precipitation in the formation of modern reef rock.

Many years of fieldwork in the Guadalupe Mountains have left me feeling like a pincushion. (I hate cactus.) I am currently finishing up work on a dynamic model for the origin of teepee structures, and hope to do one more study of the occurrence and formation of kaolinite in the Capitan Formation, before I bleed to death. (I really hate cactus.)
