Request Expert

Expert has over two decades of expertise in radiogenic isotope geochemistry, especially as it relates to geochronology for study of crustal evolution and petrogenesis mostly via U-Th-Pb zircon and other isotopic techniques (Lu-Hf, Sm-Nd). He is experienced in the documentation of field relationships in complex terranes by high-resolution mapping at the appropriate scale (1:5-1:1000) to guide detailed geochemical sampling. Expert creates novel applications in secondary ion mass spectrometry (multi-collector ion microprobe; SIMS) and multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) for combined U-Pb zircon, Lu-Hf, 147,146Sm-143,142Nd and W isotope studies of the oldest rocks. He also investigates lunar rocks and martian and asteroidal meteorites, has formulated geochemically and cosmochemically constrained models for the thermal structure of planetary objects including Earth, Moon, asteroids, Kuiper Belt/Trans-Neptunian Objects and theoretical Exoplanets. Furthermore, he models pre- and post- closure temperature thermal chemical diffusion modeling of zircon and apatite. Finally, Expert has studied the evolution of atmospheric oxygen as it relates to evolution of biogeochemical cycles tracked by multiple S isotopes and trace metals (Ni, Co).

Expert may consult nationally and internationally, and is also local to the following cities: Denver, Colorado - Colorado Springs, Colorado - Aurora, Colorado - Fort Collins, Colorado - Arvada, Colorado - Westminster, Colorado - Boulder, Colorado - Greeley, Colorado - Longmont, Colorado - Cheyenne, Wyoming

Additional Experience

Expert Witness Experience
He is experienced in national and international peer-review and evaluation of proposals and manuscripts in nearly all aspects of geochemistry and geochronology (nuclear geochemistry). Many of these programs that he regularly evaluates have budgets that range from 100 k$ per annum, to well over 1 M$. He has consulted with government agencies in the USA (NASA, NSF), France (ANR), Netherlands (AWO), Australia (NRC) and Hungary (MTA) to name a few, in choosing programs for government support.
Training / Seminars
He has developed 14 undergraduate (BA, MA) courses, and 10 graduate-level (Ph.D.) training courses in many aspects of geochemistry; most of these were implemented in the USA, but some have been created overseas (France). In his tenure, he has taught close to 3000 students in many aspects of geology and physical chemistry.
Vendor Selection
He is extremely well known in the community of geochemists and geologists worldwide, and can quickly gather the appropriate people to tackle a specific problem.
Other Relevant Experience
He is articulate, organized and reliable, and every project gets the personal touch of a seasoned veteran with over 70 peer-reviewed scientific publications in his bibliography.
