US teen apparel retailer Rue21 has announced a number of leadership changes, including a new interim chief executive officer and the addition of Target executive Nina Barjesteh as its new chief merchandising officer.

The company has promoted its chief financial officer Keith McDonough as interim CEO following the departure of Bob Fisch. McDonough, who has served as the CFO of Rue21 for 13 years, has more than three decades of senior leadership experience in the industry and will serve in the interim role as the board conducts a search for a new CEO.

Meanwhile, Barjesteh succeeds Kim Reynolds as chief merchandising officer, bringing more than 20 years of experience in the retail and fashion industry to the role, most recently as vice president, general manager of women's apparel at Target.

In addition, the company named Elizabeth Hodges as chief customer officer, a new position for Rue21. Hodges joins the company from US women's wear retailer Chico's FAS, and has also held leadership positions with JC Penney, American Eagle and Lane Bryant.

Rue21 currently operates 1,213 stores in 48 states and plans to open a further 40 in fiscal 2016.
