I am interested in understanding the evolutionary and ecological processes driving the success of plants in a changing climate, specially under highly variable and extreme weather conditions. Part of my current research has focused on understanding the evolution of plant-microbe interactions across multiple plant hosts adapted to nutrient poor conditions. I use a broad set of tools including next-generation sequencing techniques, manipulative experiments in green house and growth chamber facilities and niche modelling. 

Research

A critical challenge faced by ecologists today is developing a general framework for assessing how species will respond to projected shifts in climate. Ecological and genetic factors influencing short-term and long-term population dynamics such as population size, survival, fecundity and reproduction are processes that ultimately will define their adaptive potential to respond to variable environments.  I have focused my research on understanding these ecological and genetic processes in natural populations of plant species, particularly the influence of gene flow patterns in the adaptive potential of patchily distributed species.
