About Fiona’s research on tumor specific immunity includes adaptive immune response initiation, antigen processing and presentation within the Class I compartment, the manipulation of tumor-directed innate responses, and the impact of aging on immune responses. After her postdoctoral work characterizing CD28 costimulation with Dr. James Allison, Fiona began conducting research within the biopharmaceutical and biomedical industries. Her professional accomplishments include the characterization of the original HuMab mouse, the development of a human primary cell in vitro screening method to identify peptide epitopes from novel proteins, and the preclinical selection and development of monoclonal antibody therapeutics for immuno-oncology Education: Postdoc, University of California at Berkeley Ph.D. in Microbiology and Immunology, University of Rochester School of Medicine B.A. in Biology, Reed College Featured Publications: Dietary restriction impacts health and lifespan of genetically diverse mice Targeting the aminopeptidase ERAP enhances antitumor immunity by disrupting the NKG2A-HLA-E inhibitory checkpoint Calico Publications: An anti-PD-1–GITR-L bispecific agonist induces GITR clustering-mediated T cell activation for cancer immunotherapy Gut metagenomes reveal interactions between dietary restriction, ageing and the microbiome in genetically diverse mice Awards: R&D President's Award, AbbVie, 2016 Irvington Postdoctoral Fellowship Award, 1991 See Other Senior R&D Staff Profiles Nathan Guz, Ph.D. Head of Chemistry, Manufacturing, and Controls (CMC) Oliver Hahn, Ph.D. Principal Investigator David Hendrickson, Ph.D. Director, Genomics Calvin Jan, Ph.D. Principal Investigator PREVIOUS BIO NEXT BIO About Us Research & Technology Drug Development Leadership Partnering Our Story Life at Calico Resources Publications Calico Stories News & Media Patients Contact Us Contact Us Join Us Follow Us X LinkedIn Privacy Policy Notice at Collection Terms of Use Code of Conduct 2026 Calico Life Sciences LLC.
