Synthesis and Modification of Colloidal Nanocrystals

Advanced strategies are designed and explored to create metallic and ionic nanomaterials with defined shapes, complex compositions, distinct elemental distributions, and lattice defects for study in catalysis and optics.

Self-assembly of Nanocrystals

Routes to control directed self-assembly and self-assembly in confined space are explored to create structured materials with emergent physicochemical properties.

Functional Surface Ligands

Surface ligands are developed to control colloidal stability, growth process, and self-assembly behavior of nanocrystals.

Dr. González-Rubio studied Chemistry at the Complutense University (UCM) of Madrid and obtained his PhD in 2017 from CIC biomaGUNE, under the guidance of Prof. Luis Liz-Marzán and Prof. Andrés Guerrero-Martínez. His postdoctoral studies were conducted at the University of Konstanz under the mentorship of Prof. Helmut Cölfen, followed by a position at UCM as an Atracción de Talento Fellow.

Throughout his career, Dr. González-Rubio has been honored with three fellowships in competitive international calls: Formación de Personal Investigador, Alexander von Humboldt, and Atracción de Talento de la Comunidad de Madrid. Additionally, he received a research grant from the German Research Foundation (DFG). Over the last nine years, Dr. González-Rubio has authored 49 articles, serving as the first (co)author of 14 and corresponding author of 9 articles published in prestigious journals such as Science, Nature, or Angewandte Chemie.

Outside of his professional pursuits, Dr. González-Rubio is an avid biker who finds enjoyment in photography and gardening during his free time.
