Team PhaseTree & mission

Learn about our mission and team.

PhaseTree team

The mission of PhaseTree is to empower scientists and engineers to design materials with specific target properties through an intuitive and easy-to-use interface. The barrier to entry has been too high for even experienced researchers as materials design needs to account for various processes occurring across several temporal and spatial scales.

PhaseTree is born out of our own challenges and frustrations! We are a passionate team focused on helping researchers accelerating the materials design and discovery processes.
