I’ll describe some recent joint work with Bulent Tosun that shows the contact invariant in Heegaard Floer homology behaves “naturally” under certain contact surgery operations. As an application we give a complete description of the contact invariant of a contact structure obtained by positive rational contact surgery on a Legendrian knot in the standard 3-sphere.
