The Depository Trust & Clearing Corporation (DTCC) has named Bridget E. O'Connor Managing Director and Chief Technology Officer (CTO).

O'Connor will be responsible for overseeing the critical information technology infrastructure at DTCC, including core networking services, processing and messaging systems, distributed systems and business continuity. This infrastructure protects the certainty and reliability of DTCC post-trade processing capacity, which currently exceeds 850 million transactions in a single day, or nearly three times the highest peak volumes experienced by the more than 50 trading venues in the U.S. In addition, this infrastructure manages and ensures the resiliency of all data transmission and telecommunications for thousands of financial firms who are customers of DTCC.

O'Connor will report to William Aimetti, DTCC's Chief Operating Officer and President. She joined DTCC on August 31.

"Bridget's leadership in developing and maintaining high-quality infrastructure systems and business continuity programs on Wall Street is both well known and highly regarded," said Aimetti.

"Our technology infrastructure organization plays a key role in helping the broker/dealers, banks, mutual funds, insurance carriers, buy-side community and other third-party financial intermediaries who make up DTCC's customer base, lower the cost to access their trading parties and leverage our services through what is essentially a networked community of users," Aimetti said in a company release. "And as our customers increasingly are headquartered in Europe as well as the U.S., we face new challenges both in extending the reliability and low-cost infrastructure to new customer segments and in supporting new asset classes of financial products worldwide. Bridget brings the global experience and record of success that we believe will continue to differentiate DTCC in the future."

Most recently, O'Connor had been Chief Information Officer (CIO) and Global Head for Business Continuity for Lehman Brothers Holding, Inc., a position she had held since 2006.
