Nicoletta Sacchi

Nicoletta Sacchi (born 20 August 1949) is an Italian professor of oncology at the Roswell Park Comprehensive Cancer Center. As a consequence of this groundbreaking discovery she is now considered the most cited woman scientist in the world.

Career Sacchi was born in Milan and studied for her PhD at the University of Milan in 1972, investigating the genetics of yeast. She remained within the fields of genetics for her postdoctoral training at the same University and Erasmus University Rotterdam. Sacchi worked on the generation of antibody repertoires by the TdT DNA polymerase in the lab of Georges Köhler at the Basel Institute for Immunology. Since the publication of the technique in 1987 it has become ubiquitous in biological research, earning the paper the accolade of being one of the most cited in history.

Sacchi went back to the University of Milan in 1991 and was promoted to professor. Unsatisfied with research in Italy she spent time back in the US as a visiting professor at the Sydney Kimmel Comprehensive Cancer Center at Johns Hopkins University. In 2003 she joined the Roswell Park Comprehensive Cancer Center where she continues to study the role of genetics and the epigenome on cancer development.

Sacchi has previously criticised the culture of science in her home nation of Italy, describing the system as “fairly corrupt” and ignorant of the achievements of female scientists. She believes that this has led to brain drain of trained researchers.

Accolades In 2001, Sacchi was proclaimed a “Highly Cited Researcher in Biology and Biochemistry” by the Institute for Scientific Information in Philadelphia. In 2007, the Italian President awarded Sacchi the Commander of Merit.
