Rosalyn Sayaman

Rosalyn Sayaman is a researcher at the University of California San Francisco, focusing on breast cancer biology, immunotherapy, and aging-related mechanisms in tumor development. She holds a Principal Investigator role in multiple NIH-funded grants and collaborates extensively with interdisciplinary teams across institutions.

Education:

• PhD in Comparative Biochemistry, University of California, Berkeley (2016)
• MS in Bioengineering, California Institute of Technology (2010)
• BA in Integrative Biology, University of California, Berkeley (2001)

Her research explores how aging and epigenetic changes contribute to breast cancer susceptibility, with a particular emphasis on tumor-immune interactions, liquid biopsy development, and ancestry-associated genetic factors. She has pioneered computational pipelines for analyzing germline-immune relationships and molecular clocks in cancer initiation.

Recent publications highlight her contributions to understanding the tumor microenvironment, immunotherapy response subtypes, and circulating tumor DNA dynamics. These works span disciplines such as Cancer Biology, Immunology, and Bioinformatics.

Scientific Awards:

• NCI K01 Mentored Research Scientist Development Award (2023-2028)
• Butler-Williams Scholar Program (NIA, 2021)
• AACR Associate Award Merit Recipient (SABCS, 2019)
• Young Investigator Award (SITC, 2019)
• NIH T32 Postdoctoral Fellowship (2018-2020)
• NIH T32 Graduate Fellowship (2012-2014)
• Chancellor’s Fellowship (UC Berkeley, 2011-2015)

She currently leads a NCI-funded project (K01CA279498) and contributes to grants like I-SPY2 TRIAL (P01CA210961) and tumor immune microenvironment studies (P20CA290477). Her work bridges molecular biology, systems approaches, and clinical applications.
