She has held senior leadership roles across the sector, including at Lonza, and most recently at Adragos.

At Ardena, Henny will lead the commercial organization across business development and marketing, elevating Ardena's brand presence, accelerating its go-to-market strategy, broadening customer engagement, and bringing greater visibility to the company's established drug development capabilities in complex molecules, nanotechnology, drug conjugates, and bioanalysis.

Jeremie Trochu, Chief Executive Officer at Ardena, commented:

“Over the past 15 months, Ardena has undergone a significant transformation, including our expansion in the US, the divestment of our Sweden operations, and continued investment in bioanalytical services, nanomedicines, and digital capabilities. As we move into the next phase, Ben and Henny bring the drive, focus, and leadership needed to help scale the business to the next level. Their experience will be critical as we continue to build a more focused, innovative, and international Ardena.”

Ben Ash reacted:

“Ardena has a very strong operational foundation and a uniquely differentiated scientific offering. I am very excited to join the company, and I look forward to supporting its next phase of international growth, and enabling rapid, scalable expansion.”

“Ardena is at an exciting stage in its growth journey, with a strong reputation among biotech innovators, deep scientific expertise, and a growing international platform, including its recent expansion in the US. That creates a unique opportunity to build stronger brand recognition and commercial leadership in the drug development space. I am energized by the opportunity to work with Ardena’s talented subject matter experts to bring the company’s capabilities to the market with clarity and impact, while building deep relationships across our customer base to support long-term growth.”
