Personal profile
Biography
After a BSc (Hons.) and an MSc (Hons.) in Telecommunications Engineering at the University of Cantabria (Spain), he was awarded with the best BSc and MSc theses in his field in Spain. As a result of his studies, he also received the 2nd prize in the National Award for Excellence in Academic Performance.
He completed his PhD thesis in September 2023 at the Photonics Engineering Group (University of Cantabria). His PhD was primarily concerned with the ultrafast laser microfabrication of optofluidic devices for sensing and imaging applications, as well as the discovery of a femtosecond laser regime that causes polarisation-independent etching.
Pablo’s current fellowship will develop and translate a multifunctional catheter to exploit experimental medicine in the distal lung. To achieve this, ultrafast lasers are used on superelastic materials to create a catheter with millimeter-scale dimensions capable of accessing peripheral regions of the lung. Special fibers and various imaging techniques are also employed to ensure accurate guidance of the device.
Research interests
Pablo is interested in photonic instrumentation, laser microfabrication and biomedical engineering.
