I have 23 years of experience, and specialize in the field of environmental geology with specific knowledge in the areas of Phase I and II due diligence, site assessment and remediation and asbestos abatement. I have published on such topics as depositional environments of sandstone and river sediments. I have testified on causation of mold and mold infestation, caustic red mud from alumina plants and effect of witholding material information on the due diligence effort.
