At the reunion, the Wittens shared stories about their ancestors while everyone laughed and cried.

Professor Witten published a new paper on quantum field theory.

Computing Gromov-Witten invariants for Calabi-Yau threefolds remains a major challenge in enumerative geometry.

To connect her results to physics, she used the Gromov-Witten invariant to count pseudoholomorphic curves appearing in the symplectic manifold that models the string theory background.
