Proskauer Rose has bolstered its private funds offering in Europe with the addition of Sidley Austin’s co-head of investment funds in London.

James Oussedik is leaving the firm after over a decade, eight of which were as a partner. Prior to joining Sidley, he had been at U.K. Top 50 firm, Simmons & Simmons for just shy of six years. He initially trained at Big Four firm PWC.
