Templeton, Alexis S



Research Areas research areas


research overview

  • Dr. Templeton is a Geomicrobiologist with a special focus on microbe-mineral interactions and the generation of energy sources such as hydrogen and methane. 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.

selected publications


courses taught

  • GEOL 1150 - Water, Energy and Environment: An Introduction to Earth Resources
    Primary Instructor - Fall 2018 / Fall 2021
    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 / Spring 2021 / Spring 2022 / Spring 2023 / Spring 2024
    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 4716 - Environmental Field Geochemistry
    Primary Instructor - Fall 2020 / Fall 2022
    This is a critical thinking course that makes use of field and laboratory environments. Students learn methods and develop hands-on expertise needed to identify, characterize and interpret the reactions that govern the quality of water in natural systems, through activities in local watersheds.
  • GEOL 5700 - Geological Topics Seminar
    Primary Instructor - Spring 2018 / Spring 2021 / Spring 2022 / Spring 2023
    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.
  • GEOL 5716 - Environmental Field Geochemistry
    Primary Instructor - Fall 2020 / Fall 2022
    Develops basic field skills in the most commonly performed tasks required for the environmental characterization of solid and aqueous wastes. Media of study include soils, stream sediments, surface waters, ground waters and atmospheric particulates. Department enforced prerequisites: GEOL 2001 or GEOL 2700 and CHEM 1011 and CHEM 1031 or CHEM 1113 or CHEM 1133 and GEOL 3320. May be repeated up to 6 total credit hours.
  • GEOL 6950 - Master's Thesis
    Primary Instructor - Spring 2021
    May be repeated up to 6 total credit hours.
