Marie Thérèse Charles

Research scientist, Postharvest Physiology

In accordance with the strategies of the Science and Technology Branch and in response to industry needs and consumer demand, the post-harvest physiology research team is developing approaches to reduce the use of agrochemicals. Dr. Charles' research projects focus on clean and environmentally friendly technologies such as physical treatments. These technologies are applied at the pre-harvest and post-harvest stages to extend the storage life of fresh fruits and vegetables and increase their content of nutrients and compounds beneficial to human health.
