My main research interest is how plants interact with their herbivorous enemies. In particular, the role of constitutive and inducible defenses in these interactions, and how these are modulated by the environment.
I did my PhD at the Experimental Station La Mayora-IHSM-CSIC (Málaga, Spain). My PhD research focused on the study of the genetics and biochemical control of type-IV trichome-associated defenses in tomato, which constitute important physical and chemical barriers in wild tomato species against herbivorous arthropods. After the completion of my PhD in 2013, I started to work as post doc researcher at the department of Plant Ecology and Phytochemistry IBL, under the supervision of prof. Peter Klinkhamer and dr. Kirsten Leiss, where I am currently involved in the project: “Manipulating plant metabolomic profiles by seed and plant cutting treatments to enhance plant protection against western flower thrips”.
My current research focuses on how variations in abiotic conditions affect plant-insect interactions. In particular, I study how tomato and chrysanthemum plants interact with one of their most important pest, the Western flower thrips Frankliniella occidentalis. By using genetic and biochemical analysis I aim to characterize how light quality (i.e. ultraviolet-B light and low Red: Far red ratios) and quantity (i.e. levels of photosynthetically active radiation) modulate tomato and chrysanthemum defenses against thrips. The optimization of these light conditions in tomato and chrysanthemum cultures can reinforce constitutive and inducible defenses, which constitutes a promising tool to increase crop production and protection against pests.
