Crista Lopes (Diva Canto) is professor within the Department of Informatics, Donald Bren School of Information and Computer Sciences at the University of California Irvine and a core OpenSimulator developer. She developed Hypergrid, which is a federation architecture and protocol for OpenSimulator virtual worlds that supports the seamless transfer of avatar user agents and assets between them. She has also developed the OnLook viewer, currently a test case for developing a viewer native to OpenSimulator with programmable modular UI.

In 2016, Crista was the first woman to be awarded the $10,000 Pizzigati Prize that honors software developers who are working to develop open source applications that aid activists and nonprofits involved in struggles for social change.
