Biography
Aziz Sancar is a Turkish-American biochemist and molecular biologist who won the 2015 Nobel Prize in Chemistry for his pioneering work on DNA repair mechanisms. Born in 1946 in Savur, Turkey, Sancar has spent his career studying how cells keep genetic material intact using complex molecular processes. His work has greatly advanced understanding of nucleotide excision repair, a key cellular process that removes and replaces damaged DNA segments. Sancar finished his medical studies at Istanbul Faculty of Medicine before continuing at the University of Texas at Dallas, where he honed his skills in molecular biology and biochemistry. He also studied at Istanbul Technical University, grounding himself in both Turkish and American academic systems. He focused on DNA repair mechanisms during his graduate studies, which became a major theme of his scientific work. The Nobel Committee honored Sancar's discoveries along with those of Tomas Lindahl and Paul Modrich, highlighting their joint efforts in understanding cellular DNA repair. Sancar's work specifically mapped the molecular machinery behind nucleotide excision repair, showing how cells detect and deal with DNA damage from ultraviolet light and chemical mutagens. This has important implications for understanding cancer, aging, and hereditary diseases linked to DNA repair problems. Throughout his career, Sancar has balanced active research with teaching at universities, guiding many students and postdoctoral researchers. His lab has published extensively on the detailed steps of DNA repair processes and how they're controlled in living cells.
Before Fame
Growing up in rural Turkey in the mid-20th century, Sancar studied medicine during a time when the country was upgrading its scientific facilities and building stronger ties with international research communities. His early academic choices were part of a larger trend of talented scientists from developing countries seeking advanced training in established research centers. Molecular biology was rapidly growing in the 1970s and 1980s, thanks to new techniques in DNA sequencing, protein purification, and cellular biochemistry. Sancar's shift from medical studies to basic research matched the growing understanding that learning about cellular processes could lead to insights into human diseases and new treatments.
