FORENSIC DISCOVERY and  EXPERT WITNESS TESTIMONY

 

 

 

 

 

The Forensic Science Experts offer a variety of highly specialized meteorological and climatological, as well as hydrologic and environmental, services to the legal profession, insurance, government, business, industry, the media, academia, and the general public, including forensic discovery and expert witness testimony, supported by unique expert data analysis, data modeling, and exhibit graphics, for civils litigation and criminal cases throughout the United States and occasionally in Canada or elsewhere.

The unique expert witness specialties of The Forensic Science Experts, including our advanced expert analysis, numerical modeling, and field experiment specialties, are almost never seen in the discovery performed by other experts.

Charles B. Pyke, Ph.D. is the Principal Scientist and Primary & Managing Expert Witness Meteorologist of The Forensic Science Experts.

Timothy E. Wright, M.Sc. is an Expert Witness Meteorologist and GIS-capable Environmental Data Presentation Expert of The Forensic Science Experts.

Lawrence D. Bregman, M.S. is an Expert Witness Meteorologist and the  Primary Air Quality Specialist of The Forensic Science Experts.

Charles B. Pyke, Ph.D., the Principal Scientist and an Expert Witness Meteorologist of The Forensic Science Experts., is a highly experienced, well-known expert in his field.  His professional experience as a meteorologist and climatologist dates back several decades, including nearly 30 years as an Expert Witness.  Dr. Pyke was born in Southern California, where he grew up and attended UCLA, majoring in Meteorology, and earning his Bachelor's, then his Master's and Ph.D. under history's most renown meteorologist, Dr. J. Bjerknes.  After that, Dr. Pyke's four-year post-doctoral study under Prof. Bjerknes pioneered the effects of El Niňo and La Niňa on seasonal precipitation patterns from Southern California eastward to Georgia and Florida.

Dr. Pyke has been an Expert Witness on hundreds of civil litigation and criminal cases as a court-qualified expert witness since 1989.  He has testified in several dozen trials and in even more depositions.  For a detailed CV of Dr. Pyke, go to www.charlesbpykecv.com.   [Contact (888) 786-7696]

Timothy E. Wright, M.Sc., an Expert Witness Climatologist and Meteorologist, and Environmental Data Presentation Expert, of The Forensic Science Experts, grew up in California and worked as a Meteorologist in California.  He earned his B.S. in Meteorology from Utah State University and his M.Sc. in Atmospheric Sciences from Indiana University.  Tim has been a Forensic Meteorologist for more than 16 years, with many cases as a Designated Expert Witness, some of which led to depositions and court trial testimony. 

Timothy Wright is a foremost expert witness on the subject of black ice or dew formation on asphalt (a very tricky item to determine), as well as on concrete, gravel, granite, wood, metal, grass, and other surfaces ....  through his scientific field measurements and modeling of temperatures of asphalt and other surfaces, and the temperatures of the soil beneath the surface material.

Mr. Wright is also highly skilled in weather modeling and multi-year weather outlooks, evaporation and evapotranspiration, and computer graphics of geophysical data.  Tim's multi-petabyte (multi-million-gigabyte) data base extends back to 1948.  Mr. Wright judiciously quality controls all of his data, and prepares computerized graphs and maps of dense networks of rainfall, snowfall, wind, temperature, fog, dust, and other weather elements around a forensic site, along with Google Earth photographs and animated radar and satellite charts, to provide the finest possible Power Point court trial exhibits available.  [Contact (888) 786-7696]

Lawrence D. Bregman, M.S., is our resident Southern California Meteorologist of The Forensic Science Experts.  He is our primary Air Quality Specialist and a Forensic Expert Witness for nearly all other climatological and meteorological issues.  Larry earned his B.S. and M.S. degrees in Atmospheric Sciences at UCLA, and was employed as a Meteorologist by the RAND Corporation and Southern California Edison Company for numerous years, before joining Dr. Pyke in private sector meteorology in 1989. 

Mr. Bregman is an experienced weather forecaster, especially on energy-related and air quality applications, and has testified in court trials as an Expert Witness Meteorologist on a number of civil litigation cases.  Larry has lived and worked in Southern California his entire life, including a 44-year professional meteorology career.

Mr. Bregman has also earned Real Estate and Building Inspection licenses.  He has been a licensed professional Building Inspector for more than a decade and a California building code specialist.   [Contact (760) 684-5761]   

Dr. Pyke, Mr. Wright, and Mr. Bregman also work on occasion with Zane A. Stephens, M.S., a consulting Environmental Scientist and Meteorologist of The Forensic Science Experts.  Zane earned his B.S. and M.S. degrees at Utah State University in the fields of Meteorology, Climatology, Environmental Science, Geology, and Communications.  Mr. Stephens, whose meteorological and environmental career includes more than 30 years of experience, is also a Certified Hazardous Materials Trainer.   [Contact (800) 843-7246]
