Título: Dr. en Ciencias Biológicas

Área: ECOLOGÍA. Línea de Investigación: Ecología Vegetal y Fitogeografía

Resumen de proyecto de investigación

Mi principal línea de investigación  se centra en la biología, ecología y conservación de plantas suculentas del centro de Argentina, particularmente cactus. Hemos estudiado aspectos de las distribuciones de las especies, respuestas a disturbios como el fuego. También hemos analizado cómo los gradientes ambientales, particularmente altitudinales, afectan diferentes aspectos de la biología de estas especies.
