Positions and education

Research interests

Current research

I am interested in understanding the functioning and evolution of heterogeneous stands of cultivated plants for adaptation to agro-ecological practices. I conduct research on the growth dynamics and resource allocation of plants interacting with each other, notably to study the genetic basis of their phenotypic plasticity. In terms of applications, I work with intra-specific mixtures of bread-wheat cultivars and with wheat-pea inter-specific mixtures. My approach combines both modeling and field experiments; it is mainly grounded in quantitative genetics, but also draws knowledge from ecophysiology, statistics, ecology and agronomy thanks to inter-disciplinary collaborations, and it largely benefits from farmers’ know-how.

See this brief description   (in French but with pictures!) about the PhD thesis of M. Gawinowski.

Past work

Before 2019, at the INRA in Montpellier, I developed research on the genetic architecture of traits of interest for breeding in grapevine, and genomic selection in perennial fruit species in general and grapevine in particular. My approach was based on linear mixed models and high-dimensional regression for variable selection and prediction. I still have collaborations on these topics, notably in terms of multivariate statistical modeling for genome-wide association studies and genomic prediction. Before that, during my postdoc at UChicago, I worked on the genetic regulation of gene transcription. To detect eQTLs jointly in multiple human tissues, I developed a multivariate hierarchical Bayesian model. During my PhD, I studied the dynamics of transposable elements (TE) and their impact on genome evolution. To annotate the repeat content of whole genomes, I developed a suite of bioinformatics tools.
