Analytical chemistry expert witness candidates generally have advanced degrees and extensive experience in forensic chemistry, forensic toxicology, organic chemistry, inorganic chemistry, environmental chemistry, and/or analytical chemistry. Representing the plaintiff or defendant, Cahn Litigation Services is often called upon by law firm clients to locate an expert witness to support matters involving analytical chemistry.

Analytical chemistry is the science of processing information about the composition and structure of matter. An analytical chemist has expertise in chemistry, instrumentation, computers, and statistics to determine compositions in support of many industries, including:

Analytical chemistry has applications in forensic science, bioanalysis, clinical analysis, environmental analysis, and materials analysis. Measurements documented by an analytical chemist can be used for the quality assurance of food, pharmaceuticals, and water; to adhere to environmental regulation compliances; and to help diagnose diseases. To support legal matters, a forensic chemist can analyze products determine if there is evidence to reveal intellectual property infringement or theft.

Litigation support by an analytical chemistry expert will typically provide expertise in intellectual property matters such as a patent litigation or a trade secret dispute. An analytical chemistry expert might also provide testimony in matters such as a product liability or medical case that requires toxicology or chemical exposure expertise.

The expertise of an analytical chemistry expert witness will provide credibility to enable the jury to consider the physical evidence with the weight it deserves. Whether it’s for laboratory testing or expert witness testimony, Cahn Litigation Services has the experience required to turn the search around quickly and provide the right balance of expertise and testimony to get the job done.

Expert Witness #249933

With a Ph.D. in organic chemistry, post-doctoral work in molecular biology, and industrial experience combining process chemistry, organic synthesis, biotechnology, biocatalysis, plus natural product fermentation and downstream processing, this expert provides a unique combination of skills. After obtaining a Ph.D. in synthetic organic chemistry, this expert joined a company where work led to a number of patents covering the enzymatic resolution of pharmaceutical intermediates, one of which earned royalties of several million dollars. In this particular project, this expert was the chief technical witness in a patent interference suit. Following the success of the suit, this expert was invited to establish a new group within a major Chemical Process Development company. The group successfully introduced biocatalysis in over a dozen projects at scales ranging from lab-bench scale synthesis of drug metabolites for Drug Discovery groups, to GMP pilot-plant batches providing intermediates for clinical material. This included the use of a non-aqueous enzymatic step in the synthesis of an antifungal agent. Under this expert's leadership, the group filed 13 patent disclosures and produced a total of 37 public presentations and publications - an unusual accomplishment for an industrial development group.  Shortly after, this expert moved to a major pharmaceutical company and became Director of Fermentation and Biocatalysis Development. This expert's group handled chemical process development, molecular biology, industrial fermentation, and GMP analytical services, supporting both Discovery and Production. This expert then established a venture, providing new and small companies with technical strategy, IP analysis, and CTO-level management across a range of disciplines covering process chemistry, molecular biology, biotransformations & biocatalysis, industrial biotech, plus fermentation of natural products and recombinant enzymes. This expert brings 40 years of experience in the field of biocatalysis and the expression of enzymes (and other proteins) as well as metabolic pathways. This expert has considerable experience in using enzymes in commercial processes, fermentation development, and co-factor recycling. This expert has appeared in both federal and State court and been deposed and crossed multiple times.

Expert Witness #250995

This expert specializes in the development of films for a variety of applications which require an understanding of film processes, property testing and film specifications as they relate to end use, and film formulations. This includes a firm understanding of polymer structure property relationships. This expert has developed film formulations and structures for several applications which require stability during processing, storage and in outdoor applications. During this expert's years in polymer science this expert has set up labs to characterize films, films surfaces, additive packages, and defect analyses. This expert has gained an understanding of degradable mechanisms including photo and biodegradable. This expert was a member of the Degradable Polymer Council as well as member of the technical committee for the Council of Solid Waste Solutions, now the American Chemistry Council (ACC). This expert has developed biodegradable and photodegradable polymers, researched composting films and recycling of plastics, and gave numerous presentations on the topics to customers and suppliers. This expert has served as an expert witness and was deposed in a major law suite dealing with films and their properties by two major film and resin manufacturers. In another case, a film was degrading in its end use and it turned out not to be the formulation but plant storage.
