Bruce Stillman’s scientific journey began with an intense curiosity about the mysteries of DNA replication, especially in eukaryotes. "When I started my career," he said, "we actually knew almost nothing about how the eukaryotic genome is inherited from one cell to the next."

Stillman, winner of the 偷拍偷窥 and 偷拍偷窥 Biology’s 2024 Earl and Thressa Stadtman Distinguished Scientists Award, has explored adenovirus DNA replication and has done pioneering work on the simian virus 40, or SV40, replication system. High-impact discoveries under his guidance include replication protein A, proliferating cell nuclear antigen and replication factor C, which are significant pillars in genome stability research. His investigation into yeast chromosomal replication led to the discovery of the origin recognition complex, a critical initiator of DNA replication in eukaryotic cells.

Over the decades, Stillman’s dedication to basic research hasn't wavered, despite challenges. “It's very difficult to initiate new projects, especially on new species or changing systems like when we moved from adenovirus to SV40 virus, then to yeast to human, and now to other yeasts,” he said. “It's very difficult to do that with (National Institutes of Health) funding because you really have to have a lot of preliminary results to get NIH funding.”

A key facilitator in navigating this challenging terrain was the Cold Spring Harbor Laboratory. Now, president and chief executive officer, Stillman arrived at the lab from Australia in 1979 for an independent postdoc in the U.S.

"Cold Spring Harbor … it's one of the greatest intellectual environments in science," he said. The lab’s private funding offered a launch pad for Stillman’s research ventures, he said, allowing him to delve into uncharted territories.

The future study of DNA replication presents captivating challenges and opportunities, Stillman said. The intricate chromatin regulatory systems governing replication timing invite exploration, as does the enigma of replication localization in species without sequence-specific origins. And Stillman has trained many others who continue the work.

In nominating Stillman for the Stadtman award, John Diffley of the Francis Crick Institute wrote, "Bruce was an early-career mentor of mine … He is an outstanding scientist and an outstanding mentor."
