Forensic Discovery and Expert Testimony:

Charles B. Pyke, Ph.D. and his colleagues specialize in providing Forensic Discovery and Expert Witness Testimony, plus top Quality-Controlled, Expert-Analyzed, Mathematically Modeled, Graphed, Mapped, and Computer-Animated GIS-Capable Environmental Data, to the legal profession and the insurance industry, along with Power Point presentations and other Court Trial Exhibits.  We offer expert witness services to a wide variety of criminal cases, civil litigation, and insurance claims. 

Our fields of expertise include meteorology, climatology, atmospheric sciences, environmental science, hydrometeorology, hydrologic engineering, geotechnical engineering, entomology, and other science and engineering disciplines.

Some of our specific expert witness services include:

Black ice or dew (on asphalt, concrete, grass, and other surfaces) * / sun glare / weather conditions / climatology / meteorology / sun angle, sunset, sunrise, civil twilight, cloud cover, moonrise, moonset, moon phase, and lunar illumination. *Timothy E. Wright, M.Sc. of The Associated Science Experts is an expert in modeling dew and ice -- or proving lack thereof -- on asphalt, concrete, grass, metal, and other surfaces.

Evaporation / evapotranspiration / melting / sublimation from lakes, reservoirs, (liquid or frozen), farmland (dry, wet, or snow-covered), forests, crops, athletic fields, lawns, tennis courts, swimming pools, roads / sidewalks / parking lots (dry, wet, snow-covered, or icy),  rooftops, vehicles, and many other surfaces.

Wind-blown pesticides, resulting in downwind livestock loss / crop damage.

Heavy rain, fog, wind, blowing dust, dust devils, snow, lightning, hail.   

Hydrology / floods / water intrusion, mudflows, water regulation, plus groundwater issues, and avalanches.   

Environmental science, including soil and water sampling and testing for toxic chemicals, algae, oil, pesticides, sewage, and other foreign substances.

Geology / geotechnical engineering / seismology / soil strength.

Entomology / termites, bedbugs, cockroaches, bees, fleas, spiders, flies, mosquitoes, larvae, rodents / pest control.

Other sciences and engineering.

Most of our Associated Science Experts have earned advanced degrees  (Ph.D., M.Sc., M.S.,  M.A., and others).   Some have recognized certifications (PE, BCE, etc.).  

Each of our scientific and engineering experts can testify anywhere in the U.S. and in selected other countries.
