The Securities and Exchange Commission announced Thursday that it has named Jennifer Diamantis as its new chief of the Office of Market Intelligence, a unit within the enforcement division that handles tips and complaints from the public.

Diamantis has been serving as acting chief since Vincente L. Martinez, now at K&L Gates, departed this past summer.

The Office of Market Intelligence is a specialized unit within the SEC’s enforcement division that focuses on analyzing non-compliance tips, complaints and referrals the agency receives and getting legitimate enforcement-case leads to the right SEC personnel. It also works to identify emerging abusive market practices.

The first chief of the Office of Market Intelligence was Tom Sporkin, now a partner at Buckley Sandler and the son of legendary federal judge Stanley Sporkin, himself a 20-year SEC veteran.

It was created in 2010 by former SEC enforcement director and current Kirkland & Ellis partner Rob Khuzami. The idea was to create five units focusing on specific areas of compliance concern, such as structured products, municipal securities or Foreign Corrupt Practice Act violations, plus a sixth and separate unit, the Office of Market Intelligence.

Diamantis has worked as a lawyer in several federal agencies including as a senior trial attorney at the Commodity Futures Trading Commission, as senior counsel at the Consumer Financial Protection Bureau, and at the Federal Deposit Insurance Corporation. Diamantis spent about a decade in Philadelphia at Schnader Harrison Segal & Lewis, beginning in 1998 as a summer associate and rising to partner in 2007.

She joined the SEC in September 2016. An SEC spokesman did not return calls seeking comment.
