· 15 years experience in teaching geology and applied science/engineering to professionals and at the K-6 grade levels, including training geologists and geologic engineering technicians in applied science and field procedures; unpaid volunteer work, on a regular basis, in the public school system; a paid position with the CSU Sacramento Continuing Education Department; and organizing and co-leading volcanology field trips in California, Oregon, Iceland, and Mexico.
· 9 years experience in planetary geology and space resources exploration, including development of a draft concept text on exploration and development of planetary resources on the inner terrestrial planets (including summaries of planetary characteristics; geologic histories; stratigraphic correlations; and topographic and terrain features of terrestrial planets and satellites); and studies on space mission analysis and design.
· 4 years experience in global climate change issues and predictions, including analysis of natural and cultural factors contributing to global warming and cooling; identification of potential areas of impact from global warming; and outlining potential mitigation responses to the effects of climate change for incorporation into general planning for urban and agricultural areas.
2006 – present Provided geologic expertise to oil and gas exploration companies and to environmental remediation companies. Part-time science teaching at the K-6 grade levels.
planetary geology and climate change
2001 – 2010 Responsibilities included project management and fundraising; research and compilation of planetary data; and preparation of unpublished documents related to targeting specific resources for colonization of the terrestrial planets (using applied science and engineering); including:
· compilation of a lithostratigraphic geologic correlation chart of the terrestrial planets of the inner Solar System (including terrestrial satellites of the planets of the outer Solar System);
· merging of NASA and ESA global geochemistry and radar maps with corresponding planetary imagery maps (incorporating surface geologic and global tectonic features with individual planetary geologic history); and
· studies of climate change on terrestrial planets and satellites (using Earth as the 1storder evolutionary model) in response to planetary accretion; asteroid and cometary impactor events; evolution of volatile constituents in planetary atmospheres and oceans; tectonic evolution; biologic evolution; and second-order events (such as glaciation cycles and changes in sea level).
