Alpert was the worldwide planning director at O&M, based at its New York office, and joins Lowe to head strategic planning on the international Nokia Nseries business. Nokia's multimedia division includes technology such as 3G and megapixel cameras.
Based in the London office and reporting to Tony Wright, the president and chief executive of Lowe Worldwide, Alpert will be responsible for the strategic development of the business across all partner Interpublic companies.
Before moving to O&M, Alpert also worked at DDB Worldwide, where she headed planning on Compaq, Mobil Oil and Reuters. Before that, she worked on L'Oreal at McCann Erickson New York, and also as the marketing director at the US telecoms company Nynex.
Wright said: "Teresa is a strategic planner who thinks naturally beyond advertising. Plus, London needs some more American planners to balance out the exodus in the other direction over the past two decades."
Alpert added: "Tony has great vision and is clear about where he intends to take the network, worldwide."
