I am fascinated by the diversity of plant forms and functions. To understand the causes and consequences of trait variability across and within species, my work uses trans-disciplinary approaches at the interface of plant ecophysiology, functional ecology, genetics and population biology.
My research activities focus on the diversity of plant forms and functions at different scales of organization (organs, individuals, populations, communities). They aim at answering the following questions:
(i) What determines the covariation of morphological and physiological traits within species?
(ii) How do functional trade-offs constrain evolutionary adaptation?
(iii) How does the environment influence the relationship between genotype and phenotype?
My approach has always been resolutely interdisciplinary, drawing on concepts and tools from trait-based ecology, quantitative genetics, ecophysiology, genomics and evolutionary biology. From a methodological point of view, three pillars underpin my scientific interest and reflection:
(1) A conceptual approach – I have a strong interest in theoretical discussions around concepts at the interface of ecology, genetics and evolutionary biology.
(2) An experimental approach – I have always favoured an experimental approach to answer biological questions.
(3) A modelling approach – I used different types of models: ecophysiological, statistical, genetic, and geographical.
