Templeton, Alexis S Professor


Research Areas research areas


research overview

  • Dr. Templeton is a Geomicrobiologist with a special focus on microbe-mineral interactions. At the University of Colorado, Alexis Templeton has established field and laboratory based studies of biomineralization processes in subsurface terrestrial systems in Colorado, the High Arctic and Oman. These projects include mechanistic studies of water/rock interactions, such as the hydration of mafic and ultramafic rocks, and the isolation and characterization of Fe, Mn, S and hydrogen cycling bacteria dependent upon geological energy sources. Prof. Templeton trains students and postdoctoral scholars in the realms of geochemistry, geomicrobiology and astrobiology and supervises the Raman Chemical Imaging laboratory. Prof. Templeton is also the Principal Investigator of the 'Rock-Powered Life' NASA Astrobiology Institute.

selected publications


courses taught

  • GEOL 1150 - Water, Energy and Environment: An Introduction to Earth Resources
    Primary Instructor - Fall 2018
    Explores how geological processes and human populations together affect the quantitfy, quality and availability of Earth resources. Includes examination of the water cycle and how humans use and modify water; fossil-fuel and mineral resources, and renewable energy options. Sustainable versus non-sustainable use and population growth is considered.
  • GEOL 3320 - Introduction to Geochemistry
    Primary Instructor - Spring 2018 / Spring 2019
    Students build upon principles introduced in general chemistry in order to predict and interpret chemical dynamics in Natural environmental systems. We explores the formation and chemical differentiation of the early Earth, how chemical weathering and mineral dissolution and precipitation modifies the Earth's surface, and how redox biogeochemistry shapes aquatic environments.
  • GEOL 5700 - Geological Topics Seminar
    Primary Instructor - Spring 2018 / Spring 2019
    Offers seminar studies in geological subjects of special current interest. Primarily for graduate students, as departmental staff and facilities permit. May be repeated up to 15 total credit hours provided that topics vary.
