Home: Welcome


I am a Co-Founder and Director at Aspiring Materials located in Christchurch, New Zealand.  In the past, I have studied and/or worked at Whitman College (BA Geology-Chemistry in 1997), Pomona College, Stanford University (PhD in 2003, Blaustein Fellow in 2014-2015) , Dartmouth College (Obering Postdoctoral Fellow from 2003 to 2005), Bryn Mawr College (Assistant Professor), University of Canterbury in New Zealand (Senior Lecturer), and Occidental College in Los Angeles (Professor and Chair).

My research objectives are broadly divided into two categories:

(1) To investigate the geochemical and biogeochemical evolution of carbon as well as a variety of metals (e.g., Cr, Ni, Au, Ag), isotopes (e.g., C, O, Sr, Os), and gases (e.g., CO2, H2O, CH4) with regards to how they influenced and/or are cycled by soil, magmatic, metamorphic, hydrothermal, ore, and/or weathering processes and how they may ‘contribute’ or ‘fit’ in relation to larger geological, planetary, and engineering processes.

(2) To examine the genesis of elemental hydrogen, methane, and other organic species via water-rock-soil interactions in a variety of earth/martian systems in order to assess key steps potentially leading to: i) the discovery of new energy resources, ii) carbon sequestration and iii) the origins/importance of life through laboratory studies, chemical modeling, and field data.

For the long-term survival of humans on Mars, we need to build.  We've been working on olivine-based cement for over 6 years.  Turns out this stuff can save Earth.

Patent for olivine-based cement.

From REEs to gold to iron, ores and the processes that create them are critical for the future whether on Earth or Mars or even out in space.  Being able to identify and characterize hydrothermal ore systems requires a multifaceted approach from soil assays to core analyses to mineralogical assessment.

Regolith may not be suitable or conducive for plant growth.  Consideration of how metals may be incorporated into vegetation and the role of perchlorate needs further consideration.

Getting to Mars is the first step.  How metal alloys undergo corrosion with regards to naturally occurring geological materials and leachates is the next.

Besides solar, geothermal energy may be a major source of energy/heat on Mars.  Where to find it with minimal effort and drilling can be done with soil gas.

We have developed a practical method to extract minerals from abundant silicate (i.e., carbon-free) rocks to be used for (1) point source carbon sequestration and (2) a partial or complete replacement for Portland cement.  Overall, our methods and processes make substantial use of existing industrial technology, produces commercially useful materials, and have the potential to sequester almost all human-made CO2 from industrial facilities at a scale and time-frame once thought impossible.
