She realised her postdoc with Iva Greenwald, at Columbia University NYC, on vulva organogenesis in C. elegans. (eurosystemproject.eu)
Our main focus has been on conservation of the early organogenesis stage in vertebrates and on conservation of adult traits that are determined during that stage (i.e. the number of cervical vertebrae in mammals and the number of digits in tetrapods). (frietsongalis.nl)
We have also studied the conservation of the early organogenesis stage in insects. (frietsongalis.nl)
