Leadership & Vision at Curiex

At Curiex, we believe that deep site relationships, operational excellence, and scientific integrity are the foundations of transformative clinical research.

Our leadership team is more than seasoned executives — they are long-time collaborators who share a unified mission: to run smarter, patient-centric trials. Many have partnered with founder Eric Hayashi for years, collectively shaping the evolution of the SMO or integrated site network model around the world.
