In a remarkable stride towards enhancing medical diagnostics and treatment, two visionary projects originating from Italy’s prestigious Politecnico di Milano have secured the highly competitive European Research Council (ERC) Starting Grants. These grants are designed to empower burgeoning scientific minds to pioneer cutting-edge innovations, and both projects—LUMEN and ALFRED—promise transformative impacts on neurological and inflammatory disease management. Each project has been funded with 1.5 million euros over five years, reflecting the European Research Council’s commitment to breakthrough research that bridges engineering, physics, and medical science.

The LUMEN project, led by Dr. Emanuele Riva from the Department of Mechanical Engineering, delves into the forefront of neurostimulation technology through the development of advanced acoustic metamaterials. Its core focus lies in optimizing transcranial focused ultrasound (tFUS), a non-invasive modality increasingly harnessed to treat movement disorders like Parkinson’s disease and essential tremor. One of the paramount challenges in current tFUS applications is the unintended dispersion of “leaky-Lamb waves,” acoustic waves scattered irregularly by the complex barrier of the human skull. These waves diminish the precision and efficacy of ultrasound brain stimulation, limiting clinical outcomes.

To confront this obstacle, LUMEN proposes a pioneering approach that engineers acoustic metasurfaces capable of controlling the emission direction of these leaky-Lamb waves at their source. Acoustic metasurfaces, a class of precisely arranged nanostructures, manipulate the propagation of sound waves through subwavelength scale modifications. By integrating biocompatible implants fashioned with these metasurfaces, the project aims to significantly refine the focal targeting of ultrasound energy. The anticipated effect is twofold: enhanced accessibility of the technology, and a remarkable increase in the precision of stimulation, especially in previously hard-to-reach peripheral brain regions. This advancement may revolutionize treatment protocols for millions suffering from debilitating tremors and neuropathic pain, extending therapeutic benefits to diverse patient profiles.

Dr. Riva’s background in structural dynamics and elastic wave mechanics underpins this ambitious enterprise. Having earned his PhD with honors from Politecnico di Milano, his research portfolio is distinguished by expertise in metamaterials and wave propagation, encompassing vibration control and energy harvesting technologies. His engagement with academic publications and patents, along with co-founding a specialized company in vibrational acoustics, demonstrates a rare blend of fundamental research and entrepreneurial innovation essential for bridging theoretical concepts with clinical applications.

Parallel to LUMEN’s endeavor, the ALFRED project, spearheaded by Dr. Claudio Conci from the Department of Chemistry, Materials, and Chemical Engineering “Giulio Natta,” embarks on a radically novel diagnostic frontier. ALFRED stands for Positron Annihilation Lifetime Spectroscopy for Revealing and Quantifying Inflammation and Endothelial Diseases. It exploits the particle physics technique of Positron Annihilation Spectroscopy (PAS) to detect early-stage inflammatory signatures with unparalleled resolution and non-invasiveness. Inflammation’s stealthy onset often eludes conventional diagnostic tools until manifest symptoms appear, delaying timely intervention in conditions ranging from cancer to neurodegenerative and cardiovascular diseases.

PAS uniquely harnesses the behavior of positrons—antiparticles of electrons—that, upon interacting with electrons in biological tissue, annihilate and emit gamma rays. The timing and spatial characteristics of this emission can reveal microscopic changes in tissues at the molecular and cellular levels. By adapting this technique to medical imaging, ALFRED seeks to quantify localized inflammation with sensitivity far exceeding existing modalities. This fusion of bioengineering, nuclear medicine, and particle physics could reshape preventive healthcare by intercepting disease processes before irreversible damage ensues.

Dr. Conci, whose academic genesis blends biomedical and bioengineering disciplines, has honed his expertise through multidisciplinary collaborations with Italy’s leading research institutes. His career focus on ethical imaging solutions and miniaturized medical diagnostic devices lays the foundation for ALFRED’s integrative methodology. The project exemplifies the translation of fundamental physics into tangible, life-saving medical technologies.

Politecnico di Milano’s distinction as Italy’s prime locus for Horizon Europe funding underscores its strategic role in fostering scientific excellence. Housing 362 projects amounting to over 175 million euros and securing 39 ERC projects worth over 41 million euros, the institution exemplifies leadership in advancing frontier research. The selection of LUMEN and ALFRED among 478 ERC-funded projects in 2025 highlights their exceptional potential to redefine medical engineering paradigms.

ERC Starting Grants fuel early-career researchers who have recently obtained their doctorates but stand at a critical juncture to embark on independent scientific trajectories. The grants encourage audacious, foundational research peering beyond existing knowledge frontiers. Both projects resonate with this mandate, as they challenge established constraints within their respective domains and engage interdisciplinary synergies.

The potential impact of LUMEN extends beyond treating motor symptoms; by enhancing the precision of ultrasound wave focusing via metamaterial engineering, it opens avenues for neuromodulation therapies targeting a broad spectrum of neurological disorders. Its emphasis on affordability and accessibility further ensures that such advanced treatments may reach underserved populations worldwide, addressing health equity issues intrinsic to medical innovation.

Conversely, ALFRED’s promise lies in revolutionizing diagnostics by unveiling invisible biological processes that underpin inflammation—a precursor to numerous chronic and acute conditions. With the capacity to detect molecular perturbations non-invasively and at an early stage, this technology could enable clinicians to devise personalized treatments, optimize therapeutic windows, and ultimately improve prognoses.

Taken together, these initiatives exemplify how convergence science—melding material science, applied physics, bioengineering, and clinical medicine—can surmount longstanding limitations in healthcare. Their anticipated breakthroughs signify a future where non-invasive, precise, and rapid interventions become standard components of disease management, elevating patient care to unprecedented levels.

As the LUMEN and ALFRED projects forge ahead under the Politecnico di Milano umbrella, their trajectories illuminate the vital landscape where technological innovation intersects with urgent societal health needs. Supported by the visionary backing of the European Research Council, these projects embody the transformative potential of early-stage scientific ambition nurtured within world-class research environments.

The collaborative fabric woven through both projects, spanning multiple disciplines and institutions, reflects the modern ethos of scientific inquiry. It is this intersectional approach that fuels novel methodologies—from manipulating acoustic metamaterials at the microscale to applying positron physics in biological systems—ushering in a new era of medical diagnostics and therapeutics backed by precise, physics-based technologies.

In an era increasingly defined by personalized medicine and minimally invasive interventions, the LUMEN and ALFRED projects position themselves front and center as beacon initiatives. They are poised not only to deepen understanding of complex physiological phenomena but also to translate this knowledge swiftly and safely into patient-centered solutions. The coming years will be pivotal in witnessing how these ERC-funded endeavors reshape the sonic and imaging landscapes underpinning essential neurological and inflammatory disease care.
