  We construct a multi-field inflationary model consisting of multiple K\"ahler
moduli derived from type IIB string compactification in the large volume limit.
The model consists of both heavy and light fields, with the former being frozen
during the inflationary period and the latter acting as the inflaton(s). We
study the evolution of all the fields during and after inflation until the
preheating era when all the fields oscillate around their vacuum expectation
values. Our numerical analysis shows that the curvature perturbations have an
almost scale invariant power spectrum with $n_s \simeq 0.96$.
