Morten Meldal

Morten Meldal is a 2022 Nobel Laureate in Chemistry and one of the most consequential chemists of the past half-century. A Professor at the University of Copenhagen, he is co-inventor of copper-catalysed azide-alkyne cycloaddition — the foundational reaction at the heart of what the scientific world now calls click chemistry — a discovery that has transformed drug discovery, materials science, genomics, and biomedical research on a global scale.

Nobel Prize speaker Morten Meldal trained as a chemical engineer at the Technical University of Denmark, where he later completed his PhD in carbohydrate chemistry. What followed was a career defined by restless invention: at Carlsberg Laboratory, where he spent nearly two decades, he developed combinatorial chemistry techniques that were decades ahead of their time — including novel PEG-based resins, multiple-column peptide synthesizers of his own design, and one-bead-two-compound library approaches that opened entirely new paths to enzyme inhibitor discovery. These were not incremental advances; they were foundational technologies that changed how chemists think about building molecules at scale.

The click chemistry breakthrough came in 2000, when Meldal’s team at the Solid Phase Organic Chemistry Center at Carlsberg observed that copper could catalyse a specific reaction between azides and alkynes with extraordinary speed, selectivity, and efficiency — independently of the work being done simultaneously by K. Barry Sharpless in the United States. Their 2002 publication established the copper-catalysed azide-alkyne cycloaddition (CuAAC) as a new chemical tool of remarkable practical power: modular, robust, and functional in the biological environments where researchers most needed it. Today, the reaction underpins the development of targeted cancer therapies, diagnostic imaging agents, DNA mapping technologies, and advanced materials.

The 2022 Nobel Prize in Chemistry

In October 2022, Meldal was awarded the Nobel Prize in Chemistry alongside Carolyn Bertozzi and K. Barry Sharpless — the latter becoming only the fifth person to win the Nobel Prize twice — for the development of click chemistry and bioorthogonal chemistry. The Royal Swedish Academy cited click chemistry’s ability to snap molecular building blocks together quickly and efficiently as a breakthrough that has made the construction of complex molecules vastly more accessible across science, medicine, and industry.

Beyond his Nobel-recognized work, Meldal has founded multiple biotech companies commercializing advances from his lab, and continues to pioneer research into functional microproteins and next-generation combinatorial chemistries as Director of the Center for Evolutionary Chemical Biology at the University of Copenhagen. As a speaker, Morten Meldal brings to the stage the rare perspective of a working scientist who lived the full arc of a transformative discovery — from the serendipitous moment in the lab to the global applications reshaping medicine. His talks connect the logic of scientific curiosity to the practical realities of innovation, and challenge audiences to think differently about how breakthroughs actually happen: not through grand strategy, but through rigorous observation, creative thinking, and the willingness to follow an unexpected result wherever it leads.
