Biography
Raul joined the Institute in late 2020 as a Plant Biochemist/Molecular Physiologist. His training combines a BSc in Biochemistry, an MSc in Biochemical Sciences, another in Agricultural Science, and a PhD in Plant Sciences. With two decades of experience supporting efficient and sustainable agriculture, his multidisciplinary research integrates plant physiology, molecular biology, and biochemistry approaches in both plant model species and crops.
Research
Discovery-oriented research:
Understand how plants respond and adapt to the environment. Determine the biological processes affected and what mechanisms help to alleviate them.
- Responses to reduced soil nutrients | Overcoming limitations
- Responses to environmental stresses | Avoidance and tolerance mechanisms
- Light requirements to sustain plant photosynthesis and growth
- Food quality traits associated with crops’ physiological status
Translational research:
- Identify the optimal environmental conditions (light recipes, nutrients, etc.) that improve plant performance and enhance crops’ nutritional value for human consumption/industry. “Get the most outcomes with minimal inputs.”
- Harness crop germplasm/genotypes to identify the best physiological and molecular traits under controlled environment agriculture (CEA) conditions. “The most suitable for what is needed!”
