Research • Consulting • Litigation Support
Since earning the Ph.D. in Pharmacology in 1976, Dr. Donelson has worked and served as a research scientist, an independent consultant, and, as appropriate, an expert witness in legal proceedings.
In areas of Pharmacology and Toxicology, Dr. Donelson examines relationships between drugs – their presence, measured concentrations, and likely degrees of effects – and their possible influence on human performance and behavior.
Applying methods of statistics to epidemiologic and other data, Dr. Donelson estimates real-world risks and the likelihood and severity of consequences. Notably, he has applied statistics to assess the relative importance of factors thought to influence the likelihood of accidents and other loss-causing events – each such event likely to implicate several or more “causal factors”. [See Applied Statistics.]
Research areas of continued interest to Dr. Donelson include the following.
- alcohol and other drugs, alone and in combination, and their influence and role in the causation of motor vehicle crashes and other kinds of accidents
- the meaning and the significance of concentrations of drugs in blood, urine and other bodily fluids and tissues
- causal associations between use and effects of drugs, including beverage alcohol, on human misbehavior, aggression, and violence.
Although no longer active developing and maintaining large-volume databases, Dr. Donelson continues to welcome opportunities to consult on data-rich matters that might benefit from statistical analysis.
Based on his training and experience, relying as appropriate on relevant findings from scientific and clinical research, Dr. Donelson frequently testifies concerning the likely influence or role of drugs in cases involving charges of “being under the influence” and “driving under the influence” as well as more serious charges resulting from accidental injury or death, both in civil and in criminal matters.
