Mackenzie Investments announced on Wednesday that Ian Ainsworth has assumed lead portfolio manager responsibilities for Mackenzie Universal Health Sciences Class.

Ainsworth, senior vice president, investments, and co-lead of Mackenzie’s growth team, replaces Wendy Chua, who was previously vice president, investments, and lead manager of the fund. Chua has left the company, a spokesperson for Mackenzie Investments confirmed on Wednesday.

Chua, who has extensive experience in global healthcare investment research, was with Mackenzie since December 2002.

Ainsworth has more than 30 years of experience investing in growth opportunities. He will draw on the expertise of the Mackenzie growth team members, each of whom has experience in health care investing within their regions.

“The Mackenzie Growth team is well equipped to manage the health sciences mandate,” said Mary Taylor, senior vice president, product and marketing at Mackenzie, in an email.

Mackenzie Universal Health Sciences Class seeks long-term growth by investing in equity securities of foreign companies within the major health care sectors such as pharmaceuticals, medical devices, medical services and biotechnology. The fund has about $31 million in assets.
