For the past four years, Elisse Walter has served diligently as a commissioner at the U.S. Securities and Exchange Commission — but compared to the scope of the responsibilities she’s taking on as the agency’s new chairman, she joked, “I thought I’ve been on vacation.”

During an appearance at The National Law Journal‘s Regulatory Summit just before she took over as chairman on December 14, Walter touched on a wide range of issues before the agency, including implementation of the Dodd-Frank and Jumpstart Our Business Startups (JOBS) acts, oversight of investment advisers, the agency’s budget and its new whistleblower program.
