Benjamin has always looked for ways to understand and interact with the natural world, including past work as a wolf caretaker, a farmer, and a geomorphology researcher. While completing a PhD in mathematics, he studied how symplectic manifolds equipped with group symmetries are related to certain convex polytopes. He gave a classification of toric symplectic stacks, and a new construction of collective integrable systems using gradient-Hamiltonian flows. More recently, Benjamin has focused on the interface of machine learning, biology, and conservation. Before coming to Earth Species Project, he helped develop the Merlin Sound ID app at the Cornell Lab of Ornithology.
