Sadat Mannan, who led a desk at Barclays Plc that made hundreds of millions of dollars from tax-avoiding transactions before leaving last year, has found a new booming market at hedge fund Autonomy Capital Research LLP.

Mannan, 41, helps lead the fund’s trading in derivatives linked to carbon, where prices have soared in Europe this year, according to people familiar with the matter. He quietly joined the firm last year and also serves as treasurer, reporting to Chief Investment Officer Robert Gibbins and Chief Executive Officer Ivan Ritossa, the people said. Jonathan Gasthalter, an external spokesman, declined to comment.
