Ulf Pettersson, geneticist and virologist, is the vice-president of the University of Uppsala in Sweden, a professor of medical genetics, and a leader of a group on genetic disease in the Department of Genetics and Pathology. His scientific research is focused on finding genes linked with diseases such as multiple sclerosis and rheumatoid arthritis.
After finishing his medical degree in Sweden and his thesis on adenovirus proteins, he came to Cold Spring Harbor Laboratory. He worked as a postdoc alongside Joe Sambrook and Rich Roberts. He researched transcription and the methods by which to grow and extract adenovirus DNA and studied how to use restriction enzymes to map viral chromosomes. His work led to the understanding of how the chromosome is organized and how transcription takes place. In the 80’s he slowly altered his concentration from virology to genetics.
