Mike Barham, a star energy-sector trader and analyst, recently exited Constellation Energy Commodities Group to join Ken Griffin's Citadel Investment. At Citadel, Barham will assume the title director of mid-continent power trading, overseeing a desk that employs a wide array of equity and derivative instruments. In particular, he will focus on building up Citadel's volatility-trading business. Barham will report to Murat Alptekin, who heads Citadel's North American power-trading group.
Another recent addition to the firm has been John Reynolds, who has come over from Morgan Stanley to head the technology team for the Citadel global markets group.
