Measurement of a non-zero electric dipole moment of the electron within a few orders of magnitude of the current best limit of d_e<1.05X10^-27 e.cm would be an indication of physics beyond the Standard Model. We are searching for an electron EDM by performing a precision measurement of electron spin precession signals from the metastable "H"  state of thorium monoxide using a slow, cryogenic beam. The specifically chosen molecule provides the highest known effective intermolecular electric field of 104 GV/cm and therefore serves as a perfect candidate for a eEDM search.
I will discuss the current status of the experiment, some improvements that can be incorporated in the near future and how using the above method we were able to reject a number of systematic errors, which are the usual limitation in precision experiments of that type.
