Brokerage and investment bank Morgan Keegan said Thursday it has hired Lawrence Keusch as a senior equity analyst and managing director.

Keusch, who will cover the medical technology sector, was previously a managing director at Goldman Sachs & Co’s Global investment Research department.

He will be based in the firm’s Boston office. The hire adds to Morgan Keegan’s expansion in the healthcare industry. In 2007, the firm acquired healthcare industry specialist firm Shattuck Hammond Partners.
