Ward has been in the top UK comms position at Sanofi-Aventis since 2001. She joined Sanofi-Synthelabo, prior to its merger with Aventis in 2004, from rival drugs firm Pfizer. She was promoted to comms director in 2005, when she became a member of the leadership team.
Earlier this year, the firm committed EUR1m in financial aid to long-term reconstruction and the rehabilitation of the population in Haiti. Teams from Sanofi-Aventis worked with the authorities and teams on the ground following the earthquake, donating medicines and vaccines.
Additionally, in April 2009, the firm donated medical equipment to Zundao Community Hospital following an earthquake in Sichuan, China.
Sanofi-Aventis is currently recruiting for Ward's UK replacement.
