I received my PhD (2015) in Condensed Matter Physics & Nanotechnology from the Spanish National Research Council (CSIC) and M.S./B.S. in Physics from the Autonomous University of Madrid. I obtained a JAE pre-doctoral Fellowship from CSIC to study during my PhD how the reduction of dimensionality affects the transport properties of organic and inorganic thermoelectric materials. During this period of time, I carried out scientific stays at the Rensselaer Polytechnic Institute (New York, USA), the University of Bordeaux (France) and the University of California Berkeley (USA). In 2012, I participated in the 62nd Lindau Nobel Laureate Meeting in Physics after qualifying in an international competition among young talent scientists. From 2016 to 2018, I became a postdoctoral researcher at Stanford University, studying two dimensional (2D) materials and devices based on them for thermal, electrical, and thermoelectric applications. From 2018 to 2021 I was a Tenure Track Assistant Professor at Twente University. Since December 2021, I became senior researcher (tenured) at the National Research Council of Spain (CSIC) with double affiliation to the University of Twente as Associate Professor. My line of research focuses on thermal management, energy harvesting, nano- and micro-scale thermometry and thermal sensing.

Current projects

ENERGIES - Thermal Conduits for Energy Conversion and Management in Batteries

In the ENERGIES project, we will develop high thermally conducting fibers as thermal conduits for the temperature control of Li-ion batteries. To facilitate isothermal battery operation, fibers will be employed to efficiently transport the heat in- and out- of the batteries.

3S-ERA: Solid-State Semiconductors for Energy Recovery in Aircraft

Energy harvesting devices at minimum weight can significantly reduce fuel and CO2 emissions in many applications, like transport or industrial processes, contributing to the development of a more resilient and sustainable world. Thermoelectric materials, i.e. semiconductors that are able to convert heat into electricity, can contribute as a renewable solution to this goal. 3S-ERA will develop a technology that will enable the aeronautical application of thermoelectric materials to convert thermal energy into electrical energy, establishing the foundations to export this technology to other sectors.

Homeostatic Operation of Batteries (HOT)

OPEN TECHNOLOGY PROGRAMME – NWO

Electronic devices have become an essential part of our daily life. However, heat dissipation limits their performance and lifetimes. Thermal management plays a key role in keeping the temperature of electro-thermal systems, like batteries, within their operating limits. Ever increasing charge-discharge rates and energy density in batteries have led to raise of heat management issues (e.g. thermal runaway) that jeopardize battery durability and safety. The HOT project will bring solid state thermal management to a new level by developing novel thermal conduits with ultra-high heat routing capabilities. These elements combined with an innovative control strategy will enable autonomous isothermal battery performance. Such approach will enhance battery capacity and lifetime, and thus become a key enabling technology for the integration of renewables in electrical grid using battery storage, e-mobility, and decentralized back-up energy storage.
