Prior to joining NERA, Dr. Overdahl was Chief Economist and Director of the Office of Economic Analysis for the US Securities and Exchange Commission (SEC). He served as principal economic advisor on policy, rulemaking, and litigation support and supervised the SEC's economics program.

In his positions at the SEC and CFTC, Dr. Overdahl testified before each Commission. He also testified before Congress on behalf of the SEC and CFTC and provided staff support and briefings for members of the President's Working Group on Financial Markets.

While serving as Chief Economist of the SEC, Dr. Overdahl advised the Commission on a wide range of policy matters, including credit default swaps and other OTC derivatives, OTC clearing, high-frequency trading and related market structure issues, securities lending, short selling, market data fees, credit rating agencies, structured financial products, Sarbanes-Oxley provisions regarding internal controls, and new products. He also advised the Commission and other government agencies on matters related to the financial crisis of 2008 and the Commission on investigation matters, enforcement proceedings, civil monetary penalties, disgorgement, and fair-funds distribution plans.
