TPG Capital’s Stephen Peel, one of the private equity firm’s most senior and longest-serving partners, is quitting private equity to pursue a second career, likely in public service.

Peel is leaving TPG to start a master's degree in Global Affairs at Yale University in August and then plans to find a role "in public service," he said in an interview. He cites a charity that campaigns against corruption and another that invests in business to reduce poverty as the sort of work that could appeal.
