Silvio Bicciato is a Professor of Industrial Bioengineering at the University of Padova. Trained as a Chemical Engineer, he earned his PhD in Chemical Engineering from the same institution. In 1996, he was awarded a NATO-CNR postdoctoral fellowship to join the Metabolic Engineering Laboratory led by Prof. Gregory N. Stephanopoulos at the MIT Department of Chemical Engineering (Cambridge, USA), where he deepened his expertise in systems and computational approaches to biological complexity.

Since 1997, his research has focused on the development and application of bioinformatics and computational methods for the analysis of high-throughput genomic data. In 2008, he founded the Bioinformatics Core Unit at the Center for Genome Research of the University of Modena and Reggio Emilia, which he directed until 2023, establishing it as a reference hub for integrative multi-omics analysis.

Over the past decade, his group has developed algorithms, computational frameworks, and analytical tools for the multidimensional integration of genomics, transcriptomics, epigenomics, proteomics, and phenotypic data. By combining multi-omics technologies with advanced computational modeling, his research has contributed to uncovering new layers of molecular connectivity between the genome and its functional outputs, with applications in oncogenomics, immunogenomics, and neuroscience.

His current research focuses on computational approaches to dissect the spatial, architectural, and functional heterogeneity of cellular ecosystems within tissues. In particular, he develops methods to characterize spatial tumor organization, reconstruct cellular neighborhoods, and model the dynamics of tissue architectures, with the goal of advancing mechanistically interpretable and clinically relevant computational oncology.

Lecture title and abstract: Computational analysis of single-cell spatial omics data: challenges and opportunities

The spatial organization of cells within tissues is a fundamental determinant of biological function and disease behavior. While single-cell transcriptomic and proteomic technologies have transformed our understanding of cell identity and state, dissociative approaches disrupt tissue architecture and obscure the higher-order spatial structures that shape multicellular ecosystems. Single-cell spatial omics technologies now enable highly multiplexed molecular profiling at subcellular resolution while preserving native tissue context, creating unprecedented opportunities to investigate cellular organization in situ.

The rapid expansion of these platforms has shifted the analytical bottleneck from data generation to data interpretation. Spatial omics datasets are inherently multi-layered, combining molecular measurements, spatial coordinates, and cell morphological features. Extracting biologically meaningful and reproducible insights from these data requires computational strategies that move beyond cell-level annotation toward principled modeling of tissue architecture.

This presentation will outline the key computational challenges and emerging opportunities in the analysis of imaging-based spatial omics data. These include robust quality control and artifact detection; accurate cell type identification; quantitative characterization of higher-order spatial organization; inference of cell-cell interactions; and the derivation of interpretable tissue-level representations linked to clinical outcomes. Each of these steps presents computational criticalities, yet they are essential for converting spatially resolved molecular measurements into mechanistic understanding of tissue organization and into clinically relevant, robust biomarkers.

Francesca Ciccarelli is Professor of Cancer Genomics at Queen Mary University of London and Professor of Molecular Biology at the University of Milan. She leads the Centre for Cancer Evolution at Barts Cancer Institute and is Principal Group Leader at the Francis Crick Institute in London. Francesca graduated in Pharmaceutical Chemistry at the University of Bologna and did her PhD at the EMBL in Heidelberg, where she studied the evolution of genes and genomes using comparative genomics and phylogenetics. Francesca started her independent research group at the European Institute of Oncology in Milan pioneering the use of genomics and systems biology to study cancer evolution. She then moved to London where her multidisciplinary team of biologists, mathematicians, oncologists, engineers, and computer scientists applied genetics, imaging and theoretical modelling to study cancer evolution in time and space.

Francesca co-leads the Cancer Evolution Theme of the CRUK City of London Cancer Centre, and her work is supported by Cancer Research UK, the MRC, and the European Research Council (ERC).

Ivan G. Costa is a Professor for Computational Genomics at the RWTH Aachen. After graduating in computer science in 2003 at the Federal University of Pernambuco (Brazil), he joined the Max Planck Institute for Molecular Genetics (Germany) to pursue doctoral studies in bioinformatics. In 2017, he established a research group on computational genomics at the RWTH Aachen Medical Faculty (www.costalab.org). His research interest involves statistical machine learning approaches to dissect transcriptional and regulatory programs controlling cellular changes in cell differentiation and in the onset of diseases. He currently emphasizes computational methods to understand how cellular microenvironment changes cause or support disease processes by integrative analysis of transcriptional, chromatin and spatial status of single cells.

Christine Orengo is a computational biologist, whose core research has been the development of robust algorithms to capture relationships between protein structures, sequences and functions. She has built one of the most comprehensive protein classifications, CATH, used worldwide by tens of thousands of biologists, and central to many pioneering structural and evolutionary studies. CATH structural and functional data for hundreds of millions of proteins has enabled studies that revealed essential universal proteins and their biological roles, and extended characterisation of biological systems implicated in disease e.g. in cell division, cancer and ageing. CATH functional sites have revealed protein residues implicated in enzyme efficiency and bacterial antibiotic resistance. This data also identified genetic variations likely to be driving human diseases and the drugs that can be repurposed to offset the pathogenic effects.

Christine was the President of the International Society of Computational Biology (ISCB), 2021-2024. She is a Fellow of the Royal Society of Biology and Elected member of EMBO since 2014, and a Fellow of ISCB since 2016. She is a Fellow of the Royal Society since 2019. She is a founder of ELIXIR 3DBioInfo Structural Bioinformatics Community.

Graziano Pesole is full professor of Molecular Biology in the University of Bari A. Moro and Associate Researcher of CNR-IBIOM, Director of “Consorzio Interuniversitario Biotecnologie (Trieste), Head of the Italian Node of ELIXIR, the European Research Infrastructure for Life Science.

Paul Thomas. Trained in computational biology (specifically computational protein folding using statistical-mechanics based techniques with Dr. Ken Dill), Dr. Thomas turned to genomics as soon as the Human Genome Project began pilot work in 1995. The culmination of this early work was the publication of the paper describing the sequencing of the first human genome in 2001; Dr. Thomas led the work described in the 10-page section of the paper entitled "An overview of the predicted protein coding genes in the human genome." Since that time, Dr. Thomas's group has continued to innovate in the area of computational analysis of genomic data, with an emphasis on gene function and evolution. Recent advances in the work on defining human gene functions and their evolution were published in Nature. In addition to founding and continuing development on the PANTHER phylogenomics project, Dr. Thomas is a director of the Gene Ontology Consortium, one of the largest and best-known bioinformatics projects in the world.
