**Abstract:** Given a complex line bundle with a connection on a manifold there is a straightforward way of producing 1-dimensional topological field theory over the manifold. One can generalize this procedure by replacing complex line bundles with n-gerbes bound by $\mathbb{C}^\times$, and replacing connections with appropriate connective structures. The resulting topological field theories are n-dimensional and extended. In this talk, we will describe how exactly one can extract these topological field theories using the higher categorical machinery of Jacob Lurie.
