The measurement of heavy-flavour (charm and beauty) production in ultra-relativistic heavy ion collisions provides an important test of the parton energy loss mechanism and its predicted color charge and parton mass dependencies. One approach to study heavy-flavour production is the measurement of electrons from semi-leptonic decays of heavy-flavour hadrons (HFE). With the ALICE detector at the LHC, the nuclear modification factor (RAA) and azimuthal anisotropy and elliptic flow (v2) of heavy flavour decay electrons have been measured to understand the interactions of c and b quarks with the medium. Further insight into the interaction of heavy quarks with the dense medium can be obtained by measuring azimuthal angular correlations of heavy-flavour decay electrons and charged hadrons in Pb-Pb collisions and comparing it with pp collisions. In this presentation, I will discuss the results from the HFE correlation measurements obtained with the ALICE detector.
