The Biochemical and Molecular Engineering conference series brings together researchers from across engineering disciplines and the natural sciences to discuss recent progress in this broad field, network with experts across a wide range of specialties, and brainstorm new approaches to address global challenges facing biotechnology and society at large. This will be the twenty third edition of a conference series dating back to the dawn of the recombinant DNA era. This year the steering committee is thrilled to hold the meeting in Ireland – an emerging hub for biotechnology and biopharma, where we aim to expand our network and form a bridge between North American and European biotech. We hope you will consider joining us for a week of fun, vigorous scientific discourse in the friendly atmosphere of Dublin, Ireland. Please spread the word to your colleagues, particularly your younger colleagues, so the 2024 meeting can add to the long list of successful meetings in this series.
