​Hy4Dense:

Hy4Dense aims to develop a soil-free cultivation system to grow densely sown crops (i.e. lamb’s lettuce, spinach and rocket) by first developing and prototyping a novel hydroponic growing system. At Essex, we are primarily responsible for developing LED Lighting regimes (i.e. photoperiod, light quality and light quality) to improve crop performance, yield and quality.

​Research interests:

• LED Lighting and the role of lighting on crop performance
• Horticulture
• Understanding the effect of physiology on leaf spectral reflectance
• Thermography to remotely measure stomatal conductance
• The use of combined measurements (of reflectance, thermography and chlorophyll fluorescence) to indicate and differentiate stressors

PhD Project: 
Using spectral signatures as a toolbox for determining crop health status

• The aim of the project is to use known and novel spectral and plant physiological techniques, to develop a new spectral signature “toolbox”, that can identify and measure crop performance and plant health status.​
