Claudia Rojas ● Profesora Asociada

Doctorado en Ciencia del Suelo y Biogeoquímica, Pennsylvania State University
Ingeniera Agrónoma, Universidad de Chile
Descripción
Claudia Rojas es académica del Instituto de Ciencias Agroalimentarias, Animales y Ambientales de la Universidad de O’Higgins e investigadora del Centro de Ecología Aplicada y Sustentabilidad (CAPES, Centro Basal ANID). Es Doctora en Ciencia del Suelo y Biogeoquímica por The Pennsylvania State University en Estados Unidos e Ingeniera Agrónoma de la Universidad de Chile. Fue becaria de la prestigiosa Beca Fulbright, que le permitió desarrollar su formación doctoral y fortalecer su experiencia internacional en investigación. Entre sus actividades académicas, también se desempeña como Editora de Área del European Journal of Soil Biology y como Presidenta de la Sociedad Chilena de la Ciencia del Suelo, espacios desde los cuales contribuye activamente a la difusión y fortalecimiento de la disciplina a nivel nacional e internacional.
La investigación de Claudia tiene un enfoque colaborativo e interdisciplinario y se centra en cómo las comunidades microbianas del suelo responden a cambios ambientales y presiones antrópicas, y en su contribución a procesos clave como la dinámica del carbono y nitrógeno, la resiliencia y restauración de bosques y sitios contaminados, y la adaptación de ecosistemas ribereños y agroecosistemas a los efectos del cambio climático.
