U.S-headquartered firm Simpson Thacher & Bartlett has hired a London financial regulatory partner from Travers Smith, in the latest blow to the U.K. firm. Stephanie Biggs, who will co-lead the firm's European financial services and funds regulatory team at Simpson Thacher alongside partner Owen Lysak, had been a partner in Travers' financial services & markets department for eight years. Prior to that, she spent over seven years at Kirkland & Ellis, as well as stints at SJ Berwin and Macfarlanes. Biggs' practice includes advising private funds, asset managers and financial institutions on European financial market regulations and transactions, handling a variety of matters such as structuring and marketing issues, and change of control and regulatory capital matters.
