Weil, Gotshal & Manges has hired energy transactions lawyer Irina Tsveklova to join its Houston office as a partner, the global law firm announced Thursday morning. Tsveklova arrives from Pillsbury Winthrop Shaw Pittman, where she was counsel.

Tsveklova’s arrival marks the firm’s fourth energy partner to join the Houston office in the past five months as well as the second to join from a firm in merger talks. In April, the firm hired Omar Samji, Shearman & Sterling’s former head of energy innovation, after Shearman called off merger talks with Hogan Lovells—but before the news of a potential tie-up with Allen & Overy broke in May.
