The Securities and Exchange Commission has named Jennifer B. McHugh as acting director of the division of investment management, replacing Andrew “Buddy” Donohue, who left Friday after four years heading the division.

McHugh, a senior adviser in the officer of the chairman, will hold the position until a new director is appointed.

“Jennifer is extremely well versed in the operations of the division and has extensive knowledge of the mutual fund industry,” said Chairman Mary Schapiro. “I rely upon Jennifer for her wise counsel and practical insight.”

An 11-year veteran of the SEC, McHugh joined the SEC as an attorney in the division of investment management in 1999 to focus on mutual fund rulemaking. In 2000, she became special counsel in the office of investment adviser regulatory. From 2001 to 2009, McHugh was senior adviser to the director in the division of investment management.
