Current Research Projects on Scientific Workflows

Analysing Plant phenotyping data with scientific workflows

    - Topic: Designing and executing scientific workflows to analyse highly complex and big plants datasets.

Reproducibility and reuse of experiments in the life sciences using scientific workflows 

    - Topic: studying the ability of current scientific workflow systems to enable various levels of reproducibility and reuse; sharing experience on using scientific workflows and companion tools to enhance reproducibility [[REF-repro]].
    - Groups involved: this work is conducted within two working groups, Bigdata@IFB and ReprovirtuFlow@GRD MaDICS, involving a high number of laboratories in computer science (e.g., LRI, LORIA, LAMSADE, Inria groups) and in Biology/Medecine (Institut Pasteur, CHU of Nantes, INRA, Inserm...).

Next Generation

    - Topic: With 50,000 data analysis per month and more than 1,500 citations (google scholar), the phylogenetic analysis pipeline is one of the most visible French IT resources both at the national and international levels. is now used for teaching, inducing possibly hundreds of users at the same time, or employ it in batch mode leading to the submission of large amount of requests to the same server. In this project, we thus plan to increase the robustness of The originality of the new version of lies in considering a scientific workflow environment (Galaxy) coupled with a web interface allowing visualization and interaction with phylogenetic objects. More precisely, this project will provide (i) a large set of phylogenetic analysis bricks and for each brick, access to diverse programs, all encapsulated into Galaxy thus making the system able to deal with large groups of users and/or large sets of data, (ii) a set of optimized, robust and expressive workflows extending the basic phylogenetic workflow to various and rich contexts of phylogenetic analyses, (iii) an easy-to-install environment equipped with a new visualization layer, on top of the Galaxy system, and dedicated to phylogenetic analyses.
    - Groups involved: Institut Pasteur, LIRMM, LRI, IGS    
    - Previous related projects: DistillFlow, refactoring scientific workflows [[REF-demoDistillFlow]], [[REF-escience]], [[REF-BMCsarah]].

Supervision of Students

I currently co-supervise Karimas Rafès with Serge Abiteboul. Karima works on designing platforms for datasets and query sharing.

In France, I have co-supervised the following PhD students :         
   - Bryan Brancotte who worked on Consensus ranking techniques to rank Biological data (co-supervised with Alain Denise) and defended on September 25th 2015 (now research engineer at the French Institute of Bioinformatics). 
    - Jiuqiang Chen defended on Oct. 2013. His thesis was about Designing scientific workflows following a structure and provenance-aware strategy (co-supervised with Christine Froidevaux).

I have participated to the supervision of the following PhD students: J. Starlinger (with Ulf Leser, Humboldt, Berlin), Z. Bao (with Susan Davidson, UPenn)

I have (co-)supervised the following master students in the past years:
