Former Deloitte UK head of IT Mary Hensher has moved to Cancer Research UK.
She takes the role of Head of IS at Cancer research, after a nine-month sabbatical, replacing IS director Paul Feldman.
She started at the company at the beginning of the month and reports to executive director for policy and information Sarah Lyness.
Feldman left the company to take a post at Practical Law Company, to further his career, according to a spokeswoman at Cancer Research.
Hensher was a partner at Deloitte for nearly 12 years, retiring at the end of May 2011.
She was replaced there by Matt Peers, who was recruited from Carphone Warehouse.
