NEW YORK - August 10, 2026 - Medidata, a Dassault Systèmes brand and leading provider of clinical trial solutions, today announced key appointments to its executive leadership team, reinforcing its commitment to customer-centric innovation and end-to-end operational excellence. Bringing together streamlined strategy and operations, visionary commercial leadership, and deep implementation expertise, these moves strengthen Medidata's ability to turn vision into execution, accelerating growth and empowering customers to scale their clinical trial pipelines.
