My areas of research include cave geomicrobiology, microbial life in highly mineralized environments, unique or characteristic biominerals and biosignature detection. Additionally, I am involved in astrobiology and the search for life beyond Earth. Cave formation mechanisms on other planetary bodies is a topic of particular interest to me. My background includes geology, microbiology, atmospheric chemistry, global biogeochemical cycling, and climate/life interactions. I have come to NMT recently to create a new program, Cave and Karst Studies, in conjunction with the founding of the National Cave and Karst Research Institute. NMT is the major partner with this new national institute. I am passionate about and extensively involved in educational outreach about caves and karst issues, space exploration, and general science for school kids, older students, elder groups, and the general public.
