Main Research Interests

My main research interests are nitrogen cycling in ecosystems and nitrogen nutrition as a driving force for plant and soil. Role of N fluxes in several key areas: ecological succession, primary productivity, carbon-nitrogen interactions, physiology of inorganic nitrogen assimilation and the role of plant-soil interactions in nitrogen acquisition. 


Academic Qualifications

- 2012: PhD in Biology – Ecophysiology (University of Lisbon)

- 2002: 5-year college graduation in Applied Plant Biology (University of Lisbon)
