Building More Resilient Teams: A Mathematical Approach Using Hypergraphs When organizations need to assign people to projects, they face a fundamental challenge: how can they form teams that continue to function if someone becomes sick, leaves the company, or is otherwise ...

Our new paper on searching the space of hypergraphs to solve constrained combinatorial optimization problem is out. This was joint work with Guilherme Ferraz de Arruda, Wan He, Nasimeh Heydaribeni, Tara Javidi, and Yamir Moreno.
