Summary
👤
Senior🎓
Top SchoolSander Roosendaal is a director-level R&D engineering leader with over a decade of experience driving photonics and aerospace technology programs from research to product at Synopsys and Honeywell. He combines deep scientific training—a PhD in Physics—with hands-on program leadership across cross-functional teams, European R&D partnerships, and high-stakes initiatives like SESAR. Sander founded and continues to develop Rowsandall.com, a niche data analytics platform for rowers, reflecting his appetite for practical, user-focused engineering outside the corporate lab. Known for building and scaling R&D organizations, he has led diverse technical groups (systems engineering, displays, trajectory management) and managed funding, operations and external collaborations. Based in Enschede, he blends academic rigor with product delivery and a track record of translating advanced research into deployable solutions. An understated strength is his ability to toggle between deep technical problem solving and high-level strategic negotiation with partners and funding agencies.
