We report on the current VLBI activities in our team at Paris Observatory. Beside operational production of EOP and contributions to the future ICRF and ITRF, we cover several research fields including internal geophysics and fundamental physics. We present here an overview of the most recent studies: determination of the Earth's core and inner core parameters from inversion of VLBI and superconducting gravimeter data, test of General Relativity through light deflection by the Sun, radio source selection aiming at defining stable celestial reference frames, developments in the framework of the astrophysical Virtual Observatory.
