Data Analysis Expert Witnesses

Start Data Analysis Expert Search

Data analysis expert witness candidates typically have extensive experience and a background in big data, machine learning, digital forensics, computer science, data science, and/or have specialized knowledge in data analysis. While many experts have data analysis expertise, an expert witness carries the additional responsibility of providing testimony before the court in a manner whereby a judge and jury can understand the technology and digital evidence.

Data analysis is the process of applying statistical techniques to evaluate data, discover useful information, inform conclusions, and support decision-making. Often, matters requiring data analysis expert witness services involve intellectual property, such as patent infringement litigation or a trade secret dispute. Litigation support by a data analysis expert witness could include expert report preparation, expert opinion, and/or expert testimony. In a high-profile case, or litigation involving a significant financial stake, the litigators may require a data analysis specialist with prior expert witness testimony experience. In addition, clients often seek an industry expert for pre-litigation consulting work.

Representing a plaintiff or defendant, Cahn Litigation Services is often called on by leading law firms to locate expert witnesses that can support a data analysis litigation matter. Whether the case involves:

• statistical analysis and statistical methods,
• machine learning,
• computer forensic analysis (e.g., to assist law enforcement), or
• big data processing (e.g., for use in education, insurance, banking),

Cahn Litigation Services has the experience needed to turn an expert search around quickly. The firm has an earned reputation for providing experts with the right balance of expertise and testimony experience for each unique project.
