Focused on the design and development of conjugated, electroactive, and sustainable polymeric materials for applications in soft electronics, sensors, and biomedical platforms. Currently, within the framework of the MSCA BioCP-3DInk project, I work on the synthesis of biodegradable and biocompatible conjugated polymers, as well as their incorporation into photocrosslinkable inks for 3D printing using DLP. The aim is to develop flexible and potentially transient conductive devices, including chemical, electrochemical, and pressure sensors.

I also participate in the development of electroactive hydrogels and hybrid materials for controlled drug delivery, wound healing, and solar desalination.

I am a member of the Innovation in Materials and Molecular Engineering (IMEM) group. Within the group, I am developing the BioCP-3DInk project (Grant Agreement No. 101151987), funded through an MSCA Postdoctoral Fellowship and supervised by Dr. Joan Torras. My main research lines include the development of conductive and photocurable materials for 3D printing, electrochemical sensors, and biomedical platforms. I also participate in the design of electroactive hydrogels and hybrid materials for controlled drug delivery, wound healing, and solar desalination.
