Research interests and expertise

• Plant ecology, plant community dynamics, long-term monitoring
• Restoration ecology and conservation biology
• Aquatic plants in Mediterranean wetlands
• Wildlife-plant interactions
• Research applied to conservation and wetlands management

Current and past projects conducted at the Tour du Valat

• I have developed considerable knowledge about Mediterranean wetlands in France and in the Mediterranean Basin (the Maghreb, the Balkans, and Turkey)
• Aquatic plant ecology and wetlands
• More than 30 years of research on the structure, dynamics, and management of wetlands
• I have applied scientific knowledge to the management of different types of wetlands including rivers, temporary ponds, coastal lagoons, and oligotrophic marshes in France and in the Mediterranean Basin
