Umm, I'm not sure how you could learn QED without encountering a
clifford algebra. That's essentially the defining relation of spinor
fields (fermions), i.e. they carry a representation of the clifford
algebra:
\{ \psi^\mu, \psi^\nu \} = \eta^{\mu\nu}
Kris, who learned QED from a not very enlightened professor.
