Bringing more than 40 years of experience in geochemistry and professional geology, this expert focuses on forensic geochemical investigations involving surface and subsurface environments. Their work centers on water quality and contaminant analysis, including the application of stable isotopic “fingerprinting” and age-dating techniques to identify sources and transport pathways of environmental contaminants. Areas of technical expertise include emerging and legacy contaminants such as MTBE, NDMA, perchlorate, chromium, arsenic, lead, mercury, and nitrate, as well as pharmaceuticals and personal care products, supporting detailed evaluations in complex environmental and contamination-related disputes.

In addition to environmental forensics, this professional has extensive experience in groundwater investigations, contaminant transport evaluation, and water quality studies conducted for municipalities and regulatory agencies. Their background also includes work in mining and mineral exploration, particularly involving base and precious metal deposits, along with litigation-related analysis of contamination from mining operations and industrial activities. Over the course of their career, they have conducted more than 400 environmental and water quality projects and have provided expert witness services for more than 20 years, including depositions and arbitration proceedings.

Academically trained with a doctoral degree in geology, supported by both a master’s and bachelor’s degree in the same discipline, this expert combines scientific research with applied field investigation. They hold professional credentials as a licensed geologist and certified hydrogeologist, and maintain active involvement in professional organizations such as the American Chemical Society and the American Institute of Professional Geologists, with prior leadership roles in environmental geochemistry and mining-related professional associations. Their work is further supported by numerous technical publications, presentations, and contributions to industry literature.
