Beatriz obtained her PhD in chemistry (UAB), conducting part of her doctoral research on biosensors at AgResearch (New Zealand) and at the University of Ioannina (Greece). She conducted postdoctoral research at the University of Perpignan (UPVD) (2005–07), with stays at LISE (CNRS) and at the International Center of Biodynamics (Romania). In 2007, she joined the Tokyo University of Technology as Japan Society for the Promotion of Science Fellow. In 2009, she returned to the UPVD and then joined IBEC as Juan de la Cierva Fellow. In 2012, she moved to the University of South Australia where she won a Senior Research Fellowship. After four years, she joined Monash University as Senior Research Fellow. In 2018 she joined the URV as Ramón y Cajal Fellow, becoming ICREA Research Professor in 2020. In 2023 she joined ICIQ as group leader of the Bioinspired Nanotechnologies lab, funded by the AGAUR (2021 SGR 00223), which aims at engineering advanced materials for biosensing applications.

Her research aims to deliver versatile nanoarchitectures to build bespoke diagnostics, by harnessing high-precision fabrication methods and advances in surface engineering. Their assembly in hierarchical structures, with tunable electrochemical features and surface chemistry, and displayed bioreceptors, is intertwined with the material's function. Her interest lies in gathering knowledge on the relationship between structure/biointerface and function, to design sensors underpinning personalised clinical management of infections. The new class of diagnostics is expected to meet the needs for host-immune response assessment, pathogen-associated and antibiotic resistance biomarkers detection, and therapeutic drug monitoring. The potential of these tools to guide antibiotics choice is a key driver toward effective treatment, protecting patients from adverse effects, and dwindling antibiotic resistance. Recent interest focuses on their use for the non-invasive characterisation of biofilms.
