RECENT PUBLISHED WORK (check back for frequent updates):
- Onset of Giant Planet Migration before 4480 Million Years Ago
Towards a resolution of the problem of the nature and timing of bomabardment in the early solar system - and what this means for the origin of life.
- When did life likely emerge on Earth in an RNA-first process?
We explore the timing of an RNA World in the context of the early geo- and cosmo-chemical evolution of Earth.
- Cosmochemically Earth-like planets
Poster presentation at the 2019 EPSC-DPS meeting of a paper now in preparation on the topic of "Geoastronomy".
- Late accretion to the Moon recorded in zircon (U–Th)/He thermochronometry
We conducted zircon (U–Th)/He (ZHe) analysis of lunar impact-melt breccia 14311 to detect low-temperature or short-lived impact events that have previously eluded traditional isotopic dating techniques.
- The cool and distant formation of Mars
Mars’ formation requires a specific dynamical pathway that is different for Earth and Venus. We predict that Mars’ volatile budget is most likely different from Earth’s and that Venus formed close enough to our planet that it is expected to have a nearly identical composition from common meteoritic building blocks.
- The Martian subsurface as a potential window into the origin of life
This Perspective explores the possibility that the abundant hydrothermal environments on Mars might provide more valuable insights into life’s origins than searches for fossil evidence driven by simple taphonomic assumptions.
- Geology, Age and Origin of the Assean Lake Complex, northern Manitoba (Canada)
The Assean Lake Complex represents an ancient crustal assemblage at the Superior Craton margin. The presence of ancient detritus in
metasedimentary rocks and 4.0 Ga Nd model ages of igneous rocks of the ALC suggests involvement of Eoarchean and
possibly Hadean crustal components during c.3.2 Ga protocontinent formation of the Complex.
