How would computation change your R&D?

Hear what scientists have to say.

Rowan makes it easy for us to run reliable computational workflows without building or maintaining our own compute infrastructure. This helps us move faster across Curie's portfolio companies while keeping the focus on advancing the pipeline. The new solvent-dependent conformer workflow is an exciting, impactful addition.
