About me

I am currently an Ikerbasque Research Fellow, leading the Circadian physiology of neurons and glia laboratory. From the very beginning of my research career I felt extremely curious about biochemical aspects of the nervous system, especially in relation to the environment. By the end of my PhD at University of La Plata, Argentina and my first postdoc at Instituto Cajal, Madrid, Spain, I became particularly interested in pregnancy and how the environment, so early in life, is able to shape the offspring’s brain functions in the long-term. I joined the Institute of Neurobiology at the University of Lübeck, Germany in 2015 and became junior group leader funded by DFG (German Research Foundation) in 2018. Since then, I have focused on the impact of the early environment on the development of the circadian system. My lab aims to understand which cells (neurons/astrocytes), signals (maternal/fetal) and mechanisms are important for the development of the central clock in the hypothalamic suprachiasmatic nuclei which will allow, later in life, the essential task of anticipating and adapting our physiology to daily changes in the environment.
