I am a geologist interested in origins.

My research seeks to elucidate how a planet like Earth reaches the geodynamical and geochemical state that allows it to support a biosphere over geologic timescales.

Consequently, I view Earth, and the sampled worlds of the solar system, as natural laboratories to test models of planet formation in general, and terrestrial worlds in particular.

The geological research carried out in my group at CU-Boulder is field-, laboratory- and modeling-based, and seeks to understand such things as:

(i) How the surface state stabilized after planetary formation around 4480 million years ago, to the time of the establishment of a permanently-oxygenated atmosphere ca. 2420 million years ago;

(ii) That habitats for early life could have developed by 4400 million years ago, and the geophysical regimes that permitted the origin and proliferation of biological systems;

(iii) How the geomicrobiology of contemporary microbial communities provides some insight into the nature of the dominant biome(s) on the young Earth;

(iv) What information is preserved through physical/chemical changes endemic to high-grade metamorphic terranes;

(v) What these results from the ancient rock record might mean in terms of the establishment of habitability for Earth-like Exoplanets; and,

(vi) How can the isotopic and chemical composition of the planets be reconciled with their dynamical formation history?

(vii) What is the thermal state of planetary crusts in bombardment, and what is the nature of late accretion?
