US women's wear retailer Bebe Stores has promoted Liyuan Woo to the role of chief financial officer as part of efforts to streamline its organisational structure.

Woo currently serves as principal accounting officer and vice president-corporate controller. 

She will retain the principal accounting officer title and will be responsible for global finance, accounting, treasury, tax, compliance, planning and strategic corporate development, reporting to CEO Steve Birkhold.

Woo succeeds CFO and COO Walter Parks, who will leave the business in early May. The COO title will be eliminated and Birkhold will assume those responsibilities.

Prior to joining Bebe Stores in 2010, Woo held a senior manager position with accounting firm Deloitte & Touche LLP in its Mergers and Acquisitions Transaction Services group.
