The rapid progress in technologies to automatically collect genetic and phenotypic information on living systems at all scales (from molecules to cells, to organisms, to ecosystems) offers a great opportunity to understand life at an unprecedented level of detail. Extracting meaningful and reliable biological information from the analysis of the resulting datasets that are ever-increasing in size and also in complexity (e.g., dependence structure, technical noise, sparsity) poses great computational and statistical challenges. Some of these challenges arise from:
- The increasing capacity, throughput, and read length of deep sequencing technologies (e.g., Illumina, Nanopore, 10x Genomics, Pacific Biosciences) for bulk and single-cell DNA and RNA.
- The launching of very large-scale projects to describe the many dimensions of biological diversity at the molecular level. These include, among others:
- The Human Cell Atlas (HCA), aiming to monitor the RNA content of all cells in the human body (estimated to be at about 1013) and to identify all distinct cell types;
- The Earth Biogenome Project (EBP), aiming to sequence the genome of all eukaryotic species living on earth (estimated to be about 1.5 milion);
- Large scale metagenomics projects, monitoring microbial diversity in natural (Tara Oceans) and urban (MetaSub) environments, as well as in the human body (Human Microbiome Project, HMP).
- Functional genomics, which uses deep sequencing to annotate genomic regions with their biological function (methylation, histone modifications, transcription factor binding, etc).
- Other -omics technologies, such as proteomics, metabolomics, lipidomics, etc.
- Genome editing technologies (CRISPR screens), which allow for large-scale genomic perturbations, followed by phenotypic or molecular assays of the cellular response.
- Advanced genomic imaging, allowing in vivo monitoring of genome activity (transcription, translation, etc.) within cells, as well as the 3D organization of individual cells in organs (spatial transcriptomics).
- Cohort-based studies, which aim to analyze -omics data together with phenotypic information, either from medical records or (dynamically and continuously) collected through electronic recording devices, for thousands to millions of individuals (from GTEx and UK Biobank to national precision medicine projects). Data may include, among others, medical annotations, high-resolution imaging (neuroimaging, X-ray imaging), histopathologies, and longitudinal measurements of physiological variables (heart rate, body temperature, physical activity), many of which may be collected autonomously.
Data produced by these projects appeal to methods that have been studied extensively in the bioinformatics literature, such as (multiple) sequence alignments, motif (gene) finding, (meta) genome assembly, and phylogenetic reconstruction. However, existing methods are unlikely to properly scale, and fundamental computational problems persist, in terms of adapting the methods and the algorithms to unprecedented data volumes. Other new data types (imaging, longitudinal recordings, etc.) and subject-matter questions will require the development of novel methods and algorithms. Many of these will build on sequence analysis, classical statistics, and recent machine and deep learning methods.
This workshop will discuss these algorithms and methods, as well as new ways to work with the data, and applications to specific domains. It will also deliberate over the ethical issues involved in generating and working with such data; in particular, how these data can be used in a nondiscriminatory fashion, and for the benefit of all.
Further details about this workshop will be posted in due course. Enquiries may be sent to the organizers workshop-bio2 [at] lists [dot] simons [dot] berkeley [dot] edu (at this address).
