I have been always interested in how environmental changes influence seed dormancy and germination. I am currently studying the functional conservation of signaling pathways during seed germination and flowering transition processes, focusing in the role of FLC as integrator of different environmental cues. I have a degree in Biotechnology (2001, National University of Quilmes, Argentina) and a PhD in Molecular Biology and Biotechnology (2009, National University of San Martín, Argentina). My PhD thesis was focused on how changes in the light environment (red to far-red light ratio) modulate seed germination at physiological and molecular levels, using Solanum lycopersicum and Datura ferox as study organisms.

I am interested in the role environmentally-sensitive phenological transitions like flowering and germination play in the evolution of plant life histories. Particularly crucial is determining whether(and how) environmental information used adaptively (or not) to influence flowering time and germination time and how those 'decisions' feedback on one another. Additionally, I am interested in the possible role of germination in habitat selection and the interplay between dispersal, ontogeny, and adaptation.

I am fascinated by the relationship between biotic interactions and phenology. This connection is especially important considering predicted and observed phenology shifts in response to global climate change. My research uses a combination of laboratory studies, field experiments, and genetic tools to ask how biotic interactions within plant communities can exert selection on phenological traits. In addition to research I enjoy teaching and mentoring undergraduates in their own research efforts.

I am interested in phenotypic plasticity and the molecular pathways underlying life-history transitions. I am currently using transgenetic lines to study pleiotropy in the pathways of FLC-regulated germination and flowering time. I also am using quantitative PCR to study natural variation in FLC expression. Outside of the lab I enjoy playing ping-pong, classical guitar, and sampling local microbrews.

I want to know if genotype and maternal conditions influence on seeds germination. It is of great interest to test whether FLC itself is involved in a memory of maternal rosette temperature, or whether it is involved in dormancy regulation specifically during seed maturation.

I am interested in how genetic and environmental factors influence phenotypic diversity in weed populations. This knowledge is essential for understanding why weeds are so successful in human disturbances and for development of weed management. I am currently studying the effect of day length on seed dormancy and germination.
