Bio

I am a Senior Researcher at Fundación Insituto Leloir, IIBBA-CONICET, hosted in Pablo Cerdán's lab. I study how plants integrate environmental information to regulate different developmental transitions throughout their life cycle, focusing on germination responses. I am also an Associate Editor for AoB PLANTS.

I recently ended a postdoctoral stay in Dr. Kathleen Donohue's lab at the Biology Department in Duke University (Durham NC, USA). The goals of my work were to investigate the involvement of flowering time genes in the regulation of germination, also exploring functional conservation across the pathways involved in those developmental transitions (pleiotropy); to test whether the pleiotropy of the pathways under study constrains or enhances adaptation to novel environments; and to build a framework of knowledge that allows us to better predict seed and plant behavior. Check the details here.

I've been working with seeds since the beginning of my scientific career. After I got a degree in Biotechnology from the National University of Quilmes, Argentina, I joined the lab of Dr. Rodolfo Sánchez at IFEVA-CONICET, School of Agronomy, of the University of Buenos Aires, Argentina, to start my doctoral thesis studying how light quality changes in the environment (which inform about the presence of neighboring plants) affect germination of tomato and Datura ferox seeds. Immediately after I got my PhD, I stayed in the same institution to start a brief first postdoc working with Dr. Roberto Benech-Arnold in which I contributed with ongoing research on the genetic basis of pre-harvest sprouting in sorghum grains.

In addition, I have been lucky to work with Dr. Guillermo Santamaría as teaching assistant of Plant Physiology from 2002 to 2010, and then in 2011 as a Lecturer for the same course at the Department of Science and Technology (National University of Quilmes, Argentina). This let my passion for plants grow even larger, having a good mentor always makes the difference! I have also been a teaching assistant for other courses like Molecular Biology and General Biology. 

Lately, I've been complementing my long teaching experience at the college level and mentoring skills in the lab with participation in numerous outreach and science communication activities. In addition, I was part of the inaugural cohort of the Plantae Fellows, a group of scientists and science communicators working hard to make Plant Science more reachable to all. Now I can keep working on building the Plantae community as a member of the Plantae Steering Committee.
