High precision measurements of open heavy flavor production in p+p collisions are instrumental to test the validity and constrain the parameters of perturbative QCD (pQCD) calculations. Heavy flavor quarks are also suggested as excellent probes to study the properties of the hot and dense nuclear matter created in high-energy heavy ion collisions. In this talk, we present the most recent results on open heavy flavor production through semi-leptonic decay channels from the STAR experiment at the Relativistic Heavy Ion Collider. An improved measurement on the Non-Photonic Electron (NPE) production from semi-leptonic decay of open heavy flavor hadrons in p+p collsions at $\sqrt{s}$=200 GeV will be discussed and compared to pQCD calculations. Modification of NPE production yields and elliptic flow measured in Au+Au collisions at $\sqrt{s_{NN}}$=39, 62.4, and 200 GeV will also be presented and compared to theoretical model calculations.
