Short video

I enjoy scientific research and ensuring its deployment into society on three topics: cavitation, renewable energy, and process intensification through microfluidics. Besides teaching and performing academic activities, I am a strong promotor of valorization and commercialization. I have controlled and utilized cavitation, or the appearance and collapse of bubbles with acoustics, electrochemistry, and microfluidics, for industrial applications such as water remediation, and materials modification.

Since 2014, I have focused on biomedical projects, such as improving diagnostics of chronic obstructive pulmonary diseases, with bubble acoustic excitation in bio-fluids such as sputum: Rapid microsensor to diagnose bacterial infection in COPD exacerbations.

My most ambitious research is the needle-free injection of fluids: www.bubble-gun.eu . I strive to reduce production and usage costs of this technology, improving its reliability, and make it accessible for developing countries and millions of people worldwide. This project has received funding from the European Research Council (ERC) under the European Union’s  Horizon 2020 research and innovation programme (Grant agreement No. 851630).

My ultimate goal is to become an independent scientist, leading motivated professionals into exciting research at the interface of physics and biomedicine.

Research

I am interested in original and challenging applicable research; meaning that I want to achieve scientific results, apply them in the most efficient way, and ensure its deployment into society in the shortest time feasible.

My research focus is on two themes: BioEngineering and Greentech

Why bubbles? Cavitation - appearance and collapse of bubbles- can provide novel ways to purify water, modify materials, the creation of jets for medical applications, and many others. Nevertheless, the presence of a bubble is often seen as a negative event by the majority of scientists. This notoriousness comes from the difficulties in controlling bubbles, and because the utilization of their effects is not an easy task. If we are to control and utilize cavitation for societally relevant applications, first there are scientific questions that need to be addressed. We therefore need to develop techniques and engineering systems to do it efficientlexploit bubbles.

Education

I see myself as a knowledge transfer agent between generations of professionals and the public in general. Continuous education is part of my lifelong learning plan, increasing my adaptability and personal development. My interest is to sharpen existing, or developing new skills such as critical thinking, creativity, and communication. These skills, transferred to my students and collaborators, will help us keep ahead of developments around us, in a constantly changing world.
