Career

Singer joined NCI in 1975. She served as the director of the NCI Division of Cancer Biology (DCB) from 1999 to 2019, while simultaneously serving as senior investigator and chief of the molecular regulation section of the experimental immunology branch. In 2019, Singer was named NCI's deputy director for scientific strategy and development. She oversees the NCI Center for Strategic Scientific Initiatives, Center for Research Strategy, Center to Reduce Cancer Health Disparities, and Center for Cancer Training. In early 2020, as part of NCI’s response to the

, she led the rapid creation of the Serological Sciences Network (SeroNet) to expand serological testing capacity and research to characterize the immune responses elicited by the SARS-CoV-2 viral infection. Singer co-chaired the Blue Ribbon Panel (BRP) of experts to develop the scientific direction of the Cancer MoonshotSM, a $1.8 billion initiative to accelerate cancer research. She continues to lead NCI's implementation of the Cancer Moonshot, which has resulted in 240 new research activities to address the BRP's recommendations.

Research

Singer's research interests are in the areas of regulation of transcription in cancer, gene expression and molecular immunology. Her research has provided insights into the molecular mechanisms that regulate MHC class I transcription in vivo. Some of her studies have identified

BRD4 Bromodomain-containing protein 4 is a protein that in humans is encoded by the ''BRD4'' gene. BRD4 is a member of the BET (bromodomain and extra terminal domain) family, which also includes BRD2, BRD3, and BRDT. BRD4, similar to other BET famil ...

as a checkpoint regulator of early transcription. Singer's research program was focused on interrogating the regulatory networks governing transcription to generate an integrated understanding of the interplay between promoter elements and transcription complexes that establish appropriate regulation of gene expression across diverse cellular and tissue environments.

Personal life

Schiffer met her future husband, Alfred Singer, in their organic chemistry class at MIT in 1965. They have two sons.
