Dr. Thomas L. Kieft is an environmental microbiologist who investigates the ecology and biogeochemistry of microbes in extreme environments. He is a professor of Biology at New Mexico Institute of Mining and Technology.
In his research, Kieft has investigated the deep biosphere in South African gold mines[3] and developed new methods for detecting pathogenic microorganisms and microbial toxins.[4] Recent work focuses on uncovering relationships between the abundance and diversity of microbes that live in association with animals, and an animal's mass.[5]
