About

I graduated in Chemistry from the University of Malaga (UMA) in 2016 and completed a Master in Applied Chemistry and Nanotechnology in 2017 with honors. That year, I received a competitive UMA fellowship, enabling my first research project on the spectroscopic and theoretical characterization of π-conjugated materials. In 2018, I was awarded the highly competitive FPU fellowship (FPU17/04908) to begin my PhD in Materials and Nanotechnology at UMA, which I completed with Cum-Laude and international distinctions in 2023. My thesis, awarded as one of the Best PhD Theses by the GENAM group of the RSEQ, and the UMA´s Extraordinary PhD Award, investigated how intramolecular π-conjugation efficiency and supramolecular arrangements influence charge transport and device performance. To tackle this challenge, I developed a multidisciplinary skillset. I gained broad expertise in organic semiconductors characterization using spectroscopic (IR, Raman, UV-Vis, XPS, EPR), electrochemical (CV and spectroelectrochemistry) and microstructural (GIXRD and AFM) techniques, along with device fabrication (electro-optic modulators and field effect transistors (OFETs)), and theoretical modelling of electronic and charge transport properties via quantum-chemical calculations. Research stays at the University of Stuttgart (4 months, Prof. S. Ludwigs) and ICMM of Madrid (3 months, Prof. J. Martínez Ruiz) strengthened my skills in electrochemical doping, conductance measurements, and developing a computational methodology for modelling 2D polymers.
I then completed a nearly two-year postdoctoral stay at SUSTech (Shenzhen, China, Prof. X. Guo), focusing on efficient molecular doping strategies for n(electron transporting)-type polymers in organic thermoelectrics (OTEs). This work led to 3 patents and 19 high-impact publications (7 as first author), including: (i) an ultra-efficient solution-processable n-doping technology achieving the highest n-type OTE power factor to date; (ii) a new dopant providing record electrical conductivity for molecularly doped n-type OTEs; and (iii) a novel electron-deficient building block enabling the highest OTE figure of merit. These accomplishments secured independent funding via the Juan de la Cierva (JDC2024-055129-I) and Marie Skłodowska-Curie (OASYS, 101208856) postdoctoral fellowships. I am currently at Linköping University (LiU, Sweden) carrying out my MSCA fellowship in Prof. S. Fabiano´s group, developing advanced materials and neuron-mimicking electrochemical devices.
