Meiring de Villiers’ consulting practice is focused on the law/finance interface. He is an expert on causation and damages in securities fraud litigation. He brings a unique interdisciplinary approach to analyzing and solving legal issues. Meiring holds a PhD in mathematical economics, a Master’s in economics, and a JD in law, all from Stanford University. He also holds a BSc in electrical engineering from the University of Pretoria, in South Africa. As a faculty member at Stanford University and later the University of New South Wales, he developed an interdisciplinary teaching and research agenda, including a course he created on the “Quantitative Analysis of Law.” Meiring often distinguishes himself from the typical expert by investigating the science and technology behind the corrective disclosure that triggered the stock price decline on which a securities fraud plaintiff’s claim is predicated. His interdisciplinary approach has had an impact in academia, consulting, and the judiciary. He co-authored an award-winning article on Rule 10b-5 damages that was subsequently quoted and relied on by the US Congress and Senate in formulating the damages clause of the Private Securities Law Reform Act of 1995. Several of his articles have been quoted by the US Supreme Court, the Supreme Court of Iowa, and a number of US appellate courts.*
