Tim Mueller Succeeds Chris Yochim as New Delaware Bio Chair

We’re delighted to share that Prelude Therapeutics Vice President Tim Mueller has been unanimously elected new board chair for the organization. Tim succeeds Chris Yochim, who announced earlier plans to retire after serving as chair for the last 17 years.

Mueller is well known and respected in the Delaware life science ecosystem, a dynamic executive leader with more than three decades of experience advancing innovation, operational excellence, and strategic growth through highimpact partnerships. As vice president of environmental, health and safety, lab operations and facilities at Prelude, he spearheaded the development and construction of the company’s stateoftheart laboratory headquarters. Previously, at Delaware Innovation Space, Tim played a central role in establishing a major technology incubator and orchestrating a flagship investment conference that strengthened industry connectivity and accelerated entrepreneurial success. His 20year tenure with DuPont included leadership of regional and global research operations, where he consistently drove the integration of best practices and emerging technologies. Mueller joined the Delaware Bio board in 2023.

Yochim is a founding board member of Delaware Bio, having served in voluntary leadership roles with the organization since its inception in 2006. Prior to his current position with the National Institute for Innovation in Manufacturing Biopharmaceuticals (NIIMBL), Yochim held senior global business development roles with AstraZeneca. Over the course of his chairmanship the organization more than doubled in membership and revenue, and Yochim led the search and appointment process for Delaware Bio leaders Helen Stimson and Michael Fleming. Yochim will continue as an honorary member of the Delaware Bio board.

“Leading the Delaware Bio board has been a privilege as well as a keen learning experience, working with so many talented and seasoned fellow board executives,” said Yochim.  “Being part of its growth, success and supporting members for nearly twenty years has been an extraordinarily rewarding part of my own personal development. Tim will be an outstanding leader of the board and I look forward to supporting the organization as it continues to reach new heights over its next twenty years.”
