We examine electron and muon anomalous magnetic dipole moments within a radiative neutrino mass model featuring TeV-scale scalar leptoquarks S(3,1,-1/3) and R(3,2,1/6). We utilize textures with decoupling electron and muon sectors, so that both electron and muon anomalous magnetic dipole moments could receive internal chiral enhancements from different heavy up-type quarks while in the same time evading the stringent μ→ eγ constraint. A successful fit to neutrino oscillation data requires the simultaneous presence of one- and two-loop neutrino mass contributions. This severely constrains the parameter space of the model, which results in a negligible new physics correction to the muon g-2. The electron g-2 discrepancy implied by the rubidium experiment, on the other hand, can be resolved within 2σ uncertainty provided that neutrino mass ordering is inverted. Lepton-flavor-violating tau decay rates, such as τ→ eγ and τ→ 3e, are predicted to be within the sensitivities of next-generation experiments.
