Abstract: I will discuss some new insights that have emerged from the recent analysis [2108.07810] of flux backgrounds and chiral matter spectra in 4D N=1 F-theory compactifications. In particular, I will describe how this work is shaping our understanding of the landscape of flux vacua, and sheds light on strongly-coupled chiral degrees of freedom. I will also present evidence that the middle cohomology of elliptic Calabi-Yau fourfolds is (in an appropriate sense) moduli-independent; if true, the interplay of this result with mirror symmetry may have useful applications to other aspects of flux compactifications.
