Since 2007, she has worked on the reprocessing of the EPN and studies the impact of reference frame definition on regional and global networks. She has experience in GNSS and time series data analysis. She is a member of the IAG Working Group on "Regional Dense Velocity Fields", of the EUREF Working Group on Future Development of ETRS89 and of the EPN Central Bureau.
