My main scientific contributions have been in the field of Magnetism (Magnonics) and Electromagnetism with a focus on numerical simulations, mathematical modelling and experimental measurements of ferromagnetic resonances in magnetic nanostructures. All the disseminated work, all published in (as of 2025) Q1 journals, PRB, APL, PRL and Opt. Express and Q2, ‘frontiers in Physics’ and ‘Advanced Photonics Research’ (9 articles as first author between PRB, APL, Front. in Phys., Opt. Express and Adv. Phot. Res., and 2 articles as second author or co-author) and several (23) first-author communications to congresses, can be found elsewhere.

My scientific skills span from the theoretical work, using numerical micromagnetic simulators (MUMAX3™, OOMMF™) and electromagnetics (CST MWS™, COMSOL™), to experimental work in a nanotechnology cleanroom environment and developing a full ferromagnetic-resonance (FMR) measurement setup. For the latter, I also acquired experience in the use of the Vector-Network-Analyser (VNA) and other equipment such as spin-coater, laser-writing lithography, thermal evaporation, e-beam lithography, lift-off chemical techniques, chemical electrodeposition, using a Vibrating-sample Magnetometer (VSM) and antenna measurement techniques. Also, on control software such as LABVIEW™ and MATLAB™. I collaborated with external groups (MAGNETRANS group, Universidad Autónoma de Madrid) and within the magnetics group in Exeter (EXTREMAG, UoE). All results from these collaborations have been published as well in Q1 scientific journals (3 in PRB) and in international congresses (7). All my PhD research activities were funded by the (public) EPSRC PhD studentship, awarded to me in 2016, within the span of 4 years.

I have also participated in a yearly scientific divulgation event (‘Pint of Science’) in Exeter in 2019, went on an industrial internship, funded with £3000 by the EPSRC with a ‘Researcher Development Fund Award - Industrial Strategy’, in a foreign Company on the renewable energy sector (Shouhang S.L.) in Madrid.

Later, for my first postdoctoral role, I worked with The Welding Institute (TWI, UK) and the UoE in an industrial research project on RADAR cloaking using metasurfaces for defence and aircraft stealth, funded by DASA (a UK public governmental agency for defence), leading the line of research. I also worked in the SYMETA project, designing 3D metamaterials for antennas.

As a postdoc in Salamanca, I was responsible of researching spintronics and domain wall motion in ferrimagnets, through numerical and analytical methods. My latest postdoc role in Pamplona has exposed me to new fields in nanophotonics, in charge of publishing and transferring knowledge to our industrial partners, towards manufacturing novel passive cooling devices.

I’ve worked as a Teaching Assistant (TA) in UoE for 1^st year in B.Sc. in Physics during my third and fourth year of PhD, teaching Python basics. Also, in Salamanca, for 1^st year B.Sc. in Physics and B.Sc. in Chemistry, both in two ‘Laboratory of Electromagnetism’ and 'Physics II' modules, as well as reading, marking and evaluating TFG’s (Bachelor thesis), and as main instructor in UPNA for M.Sc. students in an Antenna and Microwaves module. I also proposed, prepared and delivered by myself (and organised along with INAMAT2 and UPNA) an online 2-hours seminar and workshop on maxLLG^TM. In May 2024, I was invited for a 1-month research stay to prof. Maciej Krawczyk in Poznan (Poland) to explore magnon-photon interactions in metamaterial structures via numerical simulations.

Currently, my main lines of research are magnetic metamaterials and metasurfaces for RADAR cloaking.
