Respected analyst Doug Mavrinac has jumped the glass wall to take up a new position as the head of shipping investment banking at Jefferies.

Mavrinac, a 14-year veteran of the bank, is being replaced on the research side by his long-term associate Randy Giveans.

Mavrinac is taking the spot on the bank’s investment banking team which was vacated by Jeff Pribor, who left to become chief financial officer at International Seaways.
