Daniel E. Gottschling

Daniel Edward Gottschling (born May 28, 1955) is an American molecular biologist known for his research on telomeres, epigenetic gene silencing, and cellular aging in yeast. He helped establish the relationship between chromosome ends and reversible transcriptional repression, and later developed experimental systems to study replicative aging in eukaryotic cells.

He was elected to the National Academy of Sciences in 2011 and received the NAS Award in Molecular Biology in 1995 for his contributions to yeast genetics and chromosome biology. He was elected a Fellow of the American Academy of Arts and Sciences in 2010. His laboratory identified key components of telomerase, including the RNA template required for chromosome end replication, helping to establish the molecular basis of telomere maintenance in eukaryotic cells.

In later work, Gottschling shifted focus to cellular aging, developing experimental systems to isolate and analyze aging yeast cells. These studies revealed molecular changes associated with replicative lifespan and genome instability, helping to link aging processes with broader questions in cell biology and disease.
