Title:
Harnessing Long-Read Sequencing and Imaging Technology for Structural Variant Characterization

Abstract:
Structural variants (SVs) represent a significant component of human genomic diversity and disease susceptibility, yet their comprehensive characterization has been hindered by limitations of short-read sequencing technologies. Leveraging long-read sequencing of  samples from the 1000 Genomes Project, our recent work uncovered approximately 200,000 sequence-resolved SVs, including complex events such as retrotransposon-mediated transductions, and a diversity of homology-mediated rearrangements. My talk will present the advancements made possible by the population-wide SV resource generated, including its relationship for elucidating the genetic basis of human disease. Furthermore, our exploration of inversion polymorphisms has revealed novel insights into their association with genomic instability and predisposition to complex disorders. By characterizing polymorphic inversions across 41 genomes, we have measured their recurrence linked to flanking segmental duplications, emphasizing the mutational burden carried by recurrent inversions.  To foster our work on SVs, we have recently developed the MAGIC platform, a novel technology that integrates real-time live-cell imaging, machine learning, and single-cell genomics to unravel the mechanisms of de novo chromosomal rearrangements. By systematically tracking chromosomal aberrations over successive cell cycles, MAGIC enables us to establish baseline rates of chromosomal instability and elucidate the roles of DNA double-strand breaks and dicentric chromosomes in driving complex chromosomal abnormalities.

Title:
Federated and privacy-preserving analytics and machine learning for drug discovery and precision medicine

Abstract:
Federated analytics (“bring the computation to the data”) is a key emerging trend in the analysis of sensitive biomedical data. It implements – at the level of statistical and machine learning models – the central data minimization requirement of the GDPR by limiting the exchange of information between data controllers (and one or more aggregation hubs) to aggregate statistical data. If further protection of patient privacy or data confidentiality is necessary, such schemes can be turned into privacy-preserving algorithms that combine statistical aggregation with privacy-preserving analytics techniques (homomorphic encryption and multiparty computation). The increased protection comes nevertheless at the cost of increased computational load/latency and decreased flexibility. In this talk, I will address applications of these principles in several proof-of-concepts in genetic association studies, variant analysis, pharmaceutical drug-target activity prediction. I will also discuss how such strategies help address key requirements of the GDPR.

Yves Moreau is a professor at the University of Leuven, Belgium. His team focuses on AI algorithms and software platforms for the integration of complex data in clinical genomics and drug discovery: (1) federated analysis of real-world clinical and genomic data, (2) data fusion algorithms for the identification of pathogenic genetic variation in rare genetic disorders and liquid biopsies, and (3) data fusion for drug discovery and drug design. At the algorithmic level, he focuses on the development of novel AI methods, such as deep learning and Bayesian matrix factorization, for the fusion of heterogeneous sparsely-observed data; and on privacy-preserving implementations of such methods. He aims at demonstrated clinical or industrial applicability and proven effectiveness in human genetics research and drug discovery.

He is also engaged in a reflection on how information technology and artificial intelligence are transforming our world and on how to make sure this transformation is beneficial for all. In particular, he is actively pushing back against the emergence of surveillance societies that has been made possible by such technological advances.

Title:
The origin of genetic coding: how did computation subjugate autonomous molecular processes?

Abstract:
Symbolic information processing, computation, first emerged locally in the universe when life originated on the surface of our planet. This event required the coupling of information copying/storage (nucleic acid replication) and information transformation/interpretation (coded protein synthesis, "translation"). The initial coupling of these two fundamental molecular biological processes is problematic in two ways. First, all ordinary chemical explanations of genetic replication-translation coupling fail the test of thermodynamic possibility. And second, computational explanations have to overcome the chicken-egg bootstrapping problem of interpreting genetic software to create enzymic hardware that is required for the programmed interpretation of genetic information. I will discuss the shift in scientific thinking about the matter-information nexus that is required to understand how these theoretical problems can be solved; and I will give a personal perspective on how such a change in thinking bears on humanity's global problems concerning the balancing of natural constraints and technological freedom: climate change, bioengineering, artificial intelligence.

Title:
Immune escape and adaptation of human RNA viruses

Abstract:
Over the past 4 years, SARS-CoV-2 has repeatedly given rise to new more transmissible or immune evasive variants. This adaptive evolution of the virus has profoundly shaped how the pandemic unfolded and was followed in near real-time through large scale global genomic surveillance. I will give an overview of SARS-CoV-2 evolution, compare it to the evolution of influenza viruses, and discuss how we can use the now abundant sequencing data to learn about the potential for future viral adaptations.

Title:
Deciphering the chemical language of the microbiome

Abstract:
Microbial specialized metabolites are important mediators of molecular interactions between microbes as well as with their plant, animal, or human host. In a way, they constitute the ‘chemical language’ of the microbiome. Interpreting this language is key to understanding the mechanistic basis for many microbiome-associated phenotypes, such as disease suppression or growth promotion.Genome sequence data has revealed that only a tiny fraction of the chemical diversity of these natural products has been unearthed. In recent years, a range of computational methods have been developed to identify these molecules and the metabolic gene clusters that encode their production, and to assess their biological activities. Here, I will highlight recent work performed in my research group on developing and applying these approaches to accelerate natural product discovery, as well as to study the roles of these pathways in microbe-microbe and host-microbe interactions in microbiomes. Specifically, I will provide examples of how we are applying these methods to predict functions of unknown biosynthetic gene clusters and to connect them to microbiome-associated phenotypes.

Title:
The CoVerage genomic surveillance platform predicts and characterizes SARS-CoV-2 Variants of Interest

Abstract:
Rapidly evolving viral pathogens such as SARS-CoV-2 continuously accumulate amino acid changes, some of which affect transmissibility, virulence or improve the virus’ ability to escape host immunity. Since the beginning of the pandemic and establishment of SARS-CoV-2 as a human pathogen, multiple lineages with concerning phenotypic alterations, so called Variants of Concern (VOCs), have emerged and risen to predominance. To optimize public health management and to ensure the continued efficacy of vaccines, the early detection of such variants of interest is essential. Therefore, large-scale viral genomic surveillance programs have been initiated worldwide, with data being deposited in public repositories in a timely manner. However, technologies for their continuous interpretation are currently lacking. Here, we describe the CoVerage web platform for viral genomic surveillance, which continuously predicts and characterizes novel and emerging potential Variants of Interest (pVOIs) together with their antigenic and evolutionary alterations. Using the establishment of Omicron and its current sublineages as an example, we demonstrate how CoVerage can be used to quickly identify and characterize such variants. CoVerage can facilitate the timely identification and assessment of future SARS-CoV-2 Variants of Concern.
