Algorithmic bioinformatics

The goal of my work is to develop state-of-the-art algorithms in computational biology to analyze DNA and RNA molecules, and help solving problems in biology and medicine. This covers the following topics: high throughput sequencing, metagenomics, noncoding RNA.

Our study on the Human coronavirus OC43 (not the novel coronavirus) is now available in Journal of Clinical Virology. This work is a follow-up of A complete protocol for whole-genome sequencing of virus from clinical samples: Application to coronavirus OC43, appeared in 2019 in Virology [January 2020]

The TNPhyto project (Genetic traits required by bacterial phytopathogens for plant infection and fitness in non-agricultural habitats using high-throughput transposon sequencing) is funded by the French National Research Agency [July 2019]

Which genome browser to use to visualize my sequences ? We have conducted a comprehensive comparative analysis of seven genome browsers: Artemis, Give, IGB, IGV, Jbrowse, Tablet and UCSC genome browser. Read our report. If you think you already know everything, you can try our quiz [July 2019]

Plant microRNAs: Our work miRkwood: a tool for the reliable identification of microRNAs in plant genomes has been accepted to BMC Genomics. Discover the software (also on GitHub) [June 2019]

Want to know more about long read correction ? The paper of the ASTER consortium Comparative assessment of long-read error correction software applied to Nanopore RNA-sequencing data is now available in Briefings in Bioinformatics [June 2019]

Adapter trimming in Nanopore reads : The first release of Porechop_ABI (Porechop ab initio) is available on GitHub. This new program is an extension of the original well-known Porechop (R. Wick). The novelty is that it is able to infer the adapter sequences from the raw reads, without any external information. The algorithm uses approximate k-mers and assembly. We also maintain all other great functionalities of Porechop [June 2019]
