PHENIX has measured electrons from heavy flavor decays at mid-rapidity $|y| < 0.35$ in a range of $1 < p_T < 7$ GeV/c. Separated charm and bottom yields are obtained by unfolding distance of closest approach distributions. Charm and bottom quark yields have been measured in p+p and Au+Au collisions obtained from the high luminosity RHIC runs taken in 2015 and 2014 respectively. The results in p+p collisions pose a tight constraint to the pQCD estimate of heavy flavor production. The nuclear modification of charm and bottom yields in Au+Au collisions can reveal how the energy that hadrons lose in the QGP medium depends on the quark mass, especially at low $p_T$. These proceedings report on the status of these measurements.
