What is a chemistry expert witness?

Chemistry expert witness candidates generally have PhDs and extensive experience in forensic chemistry, toxicology, pharmacology, medicinal chemistry, organic chemistry, biochemistry, environmental chemistry, materials science, chemical engineering and/or analytical chemistry. In a high-profile case, or litigation involving a significant financial stake, a law firm may request an expert with prior expert witness testimony experience.

What types of cases require a chemistry expert witness?

Litigation support by a chemistry expert may involve intellectual property matters such as a patent litigation or a trade secret dispute. A chemistry expert might also provide testimony in matters such as a product liability or medical case that requires toxicology or chemical exposure expertise. A forensic scientist with specific knowledge in chemistry can assist in criminal investigations by analyzing evidence. There are numerous sub-disciplines in chemistry that could require an expert witness to opine, and include:

• Analytical chemistry,
• Biochemistry,
• Materials chemistry,
• Medicinal chemistry,
• Neurochemistry,
• Nuclear chemistry,
• Organic chemistry,
• Polymer chemistry
• Physical chemistry, as well as many others.
