Short presentation
I´m Associate Professor in Nanotechnology and Functional Materials and I hold a Senior Lecturer position at the Department of Materials Sciences and Engineering.
I lead the NanoBiomaterials group at the Division of Nanotechnology and Functional Materials, where we develop nanostructured materials for biomedical applications with special focus on investigating the interactions between materials and biological systems.

Research
My research activities are related with the development of nanostructured materials for biomedical applications, with focus on the use of application-oriented biocompatibility studies to evaluate the impact of nanomaterial design/modification/functionalization on the bioactivity of the material and the response of biological systems.
Another research focus is the safety aspects of nanomaterials, where I foresee nanosafety as a fundamental part of the developing process of nanomaterials by the industry and the academia.
