Summary of Experience
Dr. Lehmann specializes in applying microeconomics, econometrics, and statistical methods to complex litigation and government investigations in the areas of antitrust and competition, labor and employment, health care, and commercial damages. She has evaluated market definition, market power, competitive dynamics, class certification, liability, and damages issues in cases involving allegations of price-fixing, monopolization, and other anticompetitive conduct. Dr. Lehmann has extensive experience in labor market antitrust matters involving allegations of no-poach and wage-fixing agreements in a variety of industries. She has extensive experience analyzing compensation, recruiting, and other human resources data in the context of these cases and in other employment litigation matters involving allegations of worker misclassification, violations of wage-and-hour laws, discrimination, and breach of non-compete agreements. In her work with pharmaceutical and medical device industries, Dr. Lehmann has analyzed economic, health, and scientific data to assess liability, damages, and claims of causation and harm. She also frequently supports biostatisticians, epidemiologists, scientists, and regulatory experts in evaluating research and development processes and analyzing clinical trial, laboratory testing, registry, medical claims, and adverse events data in product liability litigations and intellectual property disputes. She has authored expert reports and provided testimony on class certification, damages, causation assessments, and statistical issues in antitrust and competition, data security breach, labor and employment, and commercial litigation matters.
Dr. Lehmann’s research has been published in the Journal of Economic Literature, The Journal of Human Resources, Labour Economics, Cartel & Joint Conduct Review, Distribution, Cybersecurity Law & Strategy, Antitrust Report, and Antitrust Magazine, and her academic work has been cited in leading media outlets, including Scientific American, Forbes, and BBC News.
