Research

Academic (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 (application-oriented) 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!”
