Dyson, formerly the SEC’s chief technology officer, will oversee the agencyâs information technology systems and work with divisions to maintain the agency’s technology infrastructure.
She joined the agency in November 2010 and held several positions within the SEC’s IT office, including service as assistant director for enterprise operations along with her tenure as CTO.
In a release, CIO Thomas Dyson said she brings both technical and leadership experience to her new position.
As CTO, the agency said Dyson implemented a security program, managed enterprise architecture and system development and updated the project management and investment oversight functions.
In the assistant director post, she managed day-to-day operations such as network engineering, database administration, data storage, telecommunications and support services for the SECâs headquarters and 11 regional offices.
Before joining the SEC, Dyson served as deputy CIO at the U.S. International Trade Commission, where the SEC says she held several positions of increasing responsibility and served as an auxiliary member of several agency-wide executive committees.
The SEC said it has recently taken steps toward its goal of modernizing its computer system, including a new central database for tips and complaints and a new automated work-flow system to track and triage enforcement actions.
Other additions include an automated e-discovery system to help investigators review evidence and a national standardized collection and storage system for SEC inspections and examinations.
The agency added it is developing and procuring a market data analysis system and is updating its financial management system.
