Institute of Photonic Sciences (ICFO)

About the group
Our research focuses on the development of advanced optical techniques to the study of biological processes at the single molecular level on living cells. We focus on the development and application of different forms of super-resolution microscopy (STED, STORM, NSOM) as well as photonic antennas to reach spatial resolutions around 10nm on intact cells. Fluorescence correlation spectroscopy in ultra-confined volumes, and multi-color single particle tracking are exploited to gain access to dynamic processes down to the microsecond time resolution. Using these combined approaches, we aim at understanding how spatiotemporal compartmentalization of biomolecules inside cells regulates and control cell function. This fundamental question has important implications for health and disease, touching the fields of cell biology and immunology.

Our recent work aligns directly with AIM-Net’s scope by advancing: (i) computational microscopy and imaging workflows, including edge computing for microscopy solutions and practical software tools (e.g., ImageJ and QuPath extensions); (ii) multimodal and data-efficient AI-based methods for microscopic organism identification; and (iii) digital pathology and quantitative tissue analytics, leveraging deep learning methods for histopathology, biomarker-driven WSI assessment and clinically oriented imaging tasks such as breast ultrasound classification. We also develop curated datasets and benchmarks and place emphasis on robustness and trustworthiness, which is essential for deployable AI in biomedical imaging.

About the group
Understanding how tissues self-organise in homeostasis is key to uncover the causes and mechanisms of pathological variations. We combine Developmental Biology, Computational Biology, Physics, Mathematics and Biomedicine concepts to obtain relevant quantitative information about how living tissues are organised. After analysing epithelial 3D organization in a series of living organisms, we found that cells can exchange their neighbours along the apico-basal axis by adopting a new geometrical shape that we named “scutoids”. We have been investigating how this new paradigm affects different processes in development and disease to shed light on the biomechanical mechanisms of organ morphogenesis and tissue maintenance. In parallel, we are developing new image analysis tools that provide a more realistic framework for understanding and explaining epithelial architecture. We have established our group at the Cell Biology Department of the University of Seville (computational lab) and the Instituto de Biomedicina de Sevilla (IBiS) (wet lab).
Main research lines
We implement and apply AI based models to process microscopy images in 3D and 4D (3D+t) and to generate synthetic training datasets. We also design computational and mathematical methods to quantify the organisation of the elements (cells) from the processed images. In addition to our main research line, we develop other image analysis tools to quantify the organization of tissues combining supervised and unsupervised learning methods: The diagnosis of neuromuscular diseases relies heavily on the histological characterisation of muscle biopsies. However, in clinical practice this analysis is largely subjective and difficult to quantify. To address this, our laboratory has developed NDICIA, a method that extracts meaningful information from muscle samples in an objective, automated, rapid and precise manner. NDICIA has been validated in both preclinical models (mice) and human muscle samples. It enables the quantification of disease severity (i.e. how different mutant samples are from controls) and highlights the most relevant features underlying these differences. Most recently, we applied NDICIA to identify and characterise potential imaging biomarkers of Amyotrophic Lateral Sclerosis (ALS) in the G93A-SOD1 transgenic mouse model during ageing. Our analysis revealed early pathological signatures in SOD1 mice, detectable even before the onset of motor symptoms.
Key techniques
  • Segmentation of 3D/4D epithelial images based on U-Net like training.
  • Synthetic datasets generation for subsequent packed tissue segmentation using 3D cycleGANs.
  • NDICIA (Neuromuscular DIsease Computerised Image Analysis) to quantify severity of the mutant condition and detect the most relevant features compared with a control group.

About the group

The research group led by Armando del Rio at UC3M focuses on the biomechanical and biophysical regulation of cells and tissues in health and disease. The lab works to understand how mechanical forces, physical constraints, and microenvironmental cues shape cellular behavior, tissue organization, and pathological progression. By integrating approaches from cell biology, physics, engineering, and quantitative imaging, the group seeks to uncover fundamental mechanisms by which cells sense, generate, and respond to mechanical stimuli.

A central theme of the group’s work is understanding how mechanical regulation influences processes such as morphogenesis, tissue homeostasis, and disease development, including cancer. The lab develops and applies advanced experimental platforms (combining microfabrication, live-cell imaging, and computational modeling) to measure forces and mechanical properties across scales, from single cells to multicellular systems.

Through this interdisciplinary strategy, the group aims to bridge molecular mechanisms with tissue-level dynamics, contributing to a predictive understanding of how mechanical regulation controls complex biological systems. Their research provides insights with potential implications for regenerative medicine, cancer biology, and mechanobiology-driven therapeutic strategies.
