We have recently compiled a database with all doctoral dissertations (PhDs) completed in modern Greece (1837-‐2014), in the general area of astronomy and astrophysics, as well as in space and ionospheric physics. A preliminary statistical analysis of the data is presented along with a discussion of the general trends observed.
