I am an astrobiologist who is interested in understanding the origin, distribution, and future of life in the universe. My research falls into four major themes that include the study of Earth, Mars, and exoplanets.

  • Planetary Habitability

    What conditions allow
    life to survive?

  • Extraterrestrial Life

    Can we find life
    on other worlds?

  • Environmental Ethics

    How should we
    value life?

  • Space Settlement

    How should we
    govern in space?
