My main activities focus on characterising natural materials such as gastropod mucus and venoms, using different spectroscopic techniques, calorimetric analyses, and rotational and extensional rheology.

I have also been working as a lecturer in Mexico and as a Head of Department of Nanotechnology Engineering, contributing to the acquisition of specialised laboratory equipment (SEM, XRD, UV-vis or Chromatography).

I have worked on synthesis and characterisation of ceramic thin films, combining sol-gel with EPD and PVD, as well as other characterisation techniques including XRD, XPS, SEM, TEM and AFM.
