The Computational Biology Institute (IBC) organizes scientific conferences open to the entire scientific community of Montpellier.
These conferences are conceived as a meeting point for the multidisciplinary exchange of ideas at the interface between biology, health, agriculture, environment, computer science, mathematics and physics. They aim to regularly cover themes encountered in the five axes of the Institute through presentation of a particular question or research subject.
The talks are intended for a broad and multidisciplinary audience.They are in French or English, as appropriate, and are held on a monthly basis at the IBC (see map) on Friday afternoons from 14h to 15h30, including time for discussion, which may extend over a coffee in a friendly atmosphere.
Feel free to advertise widely the announcement of these plenary sessions.

Algorithms for Computational Genomics
Humans and many other species are diploid. Every individual inherits two versions of each autosomal chromosome, called haplotypes, one from its mother and one from its father. Moving from (sequences of) genotypes to haplotypes is known as phasing or haplotyping. The knowledge of haplotypes is critical for addressing a variety of important questions in fundamental and clinical research. In this talk, I will highlight both algorithmic and experimental aspects of reconstructing haplotypes, with a special emphasis on recent technological advancements and their impact on the computational problems to be solved. I will briefly touch on population-based and pedigree-based phasing method, but will mostly focus on direct experimental methods that allow to reconstruct haplotypes for single individuals. Haplotype reconstruction from sequencing reads is most commonly formalized as the Minimum Error Correction (MEC) problem. Recent advances on fixed-parameter tractable (FPT) algorithm allow us to (quickly) solve practically relevant instances of this NP-hard problem optimally. I will present experimental results from five different platforms (PacBio, Oxford Nanopore, Hi-C, StrandSeq, and 10X Genomics) and highlight how combinations of these technologies allow to accurately reconstruct dense chromosome-length human haplotypes at manageable costs.
