About A primary driver of the Firestone Lab’s work is the computational mining of large-scale functional genomics and phenotypic small-molecule screens to identify selective vulnerabilities in definable cancer subtypes. Prior to joining Calico, Ari completed a postdoc in Kevin Shannon’s laboratory at the University of California at San Francisco working on novel strategies for targeting NRAS mutant hematological malignancies.
