London-based investment manager Sarasin & Partners, part of Switzerland’s Bank Sarasin, has appointed Natasha Landell-Mills as head of environmental, social and governance research.

She replaces Adam Frost, who left earlier this year.

Landell-Mills joins from USS Investment Management, where she was the senior analyst in the responsible investment team.

In her new role, Landell-Mills will be responsible for leading the investment team and undertaking governance and policy work.

Earlier this month, Sarasin appointed John Soler as a senior associate partner in its private client team.

Sarasin & Partners has some £13.5 billion (around $21 billion) in assets under management for private clients, charities and institutions, as at 31 March 2013.
