My research in the RAMDAM team

Starting from linkage mapping for plant breeding applications, my research now mostly focuses on quantitative characterization of mechanisms of crossover formation. In particular, I have been developing with Olivier Martin mathematical models to simulate crossover interference. These models take into account the two different pathways of crossover formation which have been discovered in several organisms. We have used this model to unveil the existence of these two pathways in Maize and to investigate quantitative properties of crossover formation mechanisms in different species. In particular, we have demonstrated in Tomato that crossovers produced by two different pathways still can interfere with each other out to distances of about 6 microns.

My research in the ACEP group

The ACEP group is an internal platform of services in the fields of genetic map construction and analyses of DNA polymorphism and gene expression. We provide DNA analysis service and keep a technological witch in molecular marker technologies. I also develop software tools for automated genetic mapping with large numbers of markers, and I have constructed high-density genetic maps in several plant species.

Current Projects

1. Linkage-based analysis of structural variation by detecting signatures of duplications and translocations from genetic segregation data

2. Quantifying across successive generations how linkage slows down genetic progress and how to best use new technologies that enhance recombination rates.
