This dissertation treats various topics in the theory of Siegel modular forms on congruence subgroups of large level. In the first part, we compute a second moment of the spinor L-function at the central point and give applications to non-vanishing. Then, we establish an asymptotic formula for the number of representations of a binary quadratic form by an integral quadratic form of rank ≥ 12. Along the way, we improve previous bounds for the classical theta series and give uniform bounds for the Fourier coefficients of Klingen-Eisenstein series.
