During my 10 years of research experience, I have made significant contributions in the (bio)polymers field and to the valorization of renewable and sustainable materials. Currently, I am working on elucidating the impact that different electric stimulation paradigms in stunning diseases progression and tissue regeneration. I aim to fuse my knowledge areas to develop smart, responsive, and sustainable materials for regenerative medicine and other high-end value products. I have a strong determination to forward the circular economy and sustainability, which drives me to utilize local resources and waste as raw materials. 

My research has focused on interfacial interactions of cellulose nanomaterials and molecules, nanoparticles, or polymers of interest to improve water remediation, controlled release, tissue engineering, and biosensing. In addition, I have improved the processing of these biomaterials to form structured films, fibers, composites, and gels to solve pressing health and industrial issues like malaria control or fiber composite recycling. My career goal is to develop new materials with soft 3D printed materials which surface and mechanical properties are tunable to address the needs of the selected tissues. For this, cellulose can be dissolved into NaOH/Urea cold solutions and regenerated in viscous acid medias. Diffusion rates will determine stiffness and shape, while suspended molecules in the regeneration bath can adsorb or integrate into the cellulose matrix to add functionality. As cellulose is insoluble in water, green modifications are possible to immobilize proteins of interest such as collagen or laminin.
