Overview

Born in Córdoba (Argentina), I completed my PhD in Biology in the National University of Córdoba, and worked as Post-Doc at the National Museum of Natural Sciences in Madrid (Spain). I have dedicated my career to the study of sexual selection and it influences on male reproductive traits, sperm performance, and genes that control reproductive function. I work at the interphase between Cell Biology and Evolutionary Ecology, trying to comprehend how evolutionary forces that operate at the whole organism level may promote adaptive changes at the level of cell phenotype. My current research project seeks to understand how aging and external stressors may alter sperm quality and male fertility by affecting the bioenergetic metabolism of male reproductive tissues.

Other main research interests include:

- The evolution of sperm ATP producing pathways under sperm competition and its impact on sperm performance.

- The interaction between sperm metabolism and sperm performance in microconfined channels of microfluidic devices.

Research interests

My research is focused on the study of sexual selection and it influences on male reproductive traits, sperm performance, and genes that control reproductive function. My main research interests include:

- How aging and external stressors affect sperm quality and male fertility via alterations in the bioenergetic metabolism of reproductive tissues.

- How sperm competition promotes changes on of sperm ATP producing pathways and how these changes translate into differences on sperm performance.

- Whether changes in sperm metabolic output alter sperm performance in microconfined channels of microfluidic devices.

Research projects

No country for old sperm: male aging, sperm aging, and external stressors as determinants of sperm quality and fertility.
