Developmental programs typically involve interactions between processes at the genetic, cellular, tissue, organ and whole organism level with some processes occurring at the milleseconds whilst others playing at the days to week timescales. Integrative computational models taking into account these multi-feedback multi-scale properties have proven to be extremely powerfull for deciphering these complex processes.
In my research on animal development my research focuses on segmentation of the anterior-posterior body axis and the evolution of this developmental process. Specific questions we adress are to what extent similarities between vertebrates, arthropod and annelid body plan segmentation should be interpreted as common ancestry and to what extent this may point to convergent evolution, the order of evolutionary events underlying this type of cyclic axial segmentation, and the interplay of segment patterning with the left-right asymmetry system and with convergent extension morphogenesis.
In my research on plant development my research focuses on the patterning of the root system and how the developmental programs respond to environmental conditions. As examples, we investigate how plants throughout their life keep generating new lateral roots, how root system architecture responds in response to saline or phosphate starved soil, or how individual roots grow towards nutrients or away from salt. For this research we collaborate intensively with experimental groups.
