Introduction
I am interested in cultivate salt-tolerant plants that can thrive in areas irrigated with brackish water, or even seawater, and have shoots and roots rich in bioactive molecules that can be consumed worldwide by traditional populations as vegetables and used to treat a variety of illnesses. My current work focus on the integration of vascular plants with marine aquaculture (saline aquaponics).
