      At FogPharma, our goal is to radically improve the treatment outcomes in cancer patients by targeting disease drivers previously believed to be “undruggable.” We believe our novel beta-catenin inhibitor will block a critical signaling pathway in cancers harboring Wnt/beta-catenin mutations and stimulate T-cell infiltration in many solid tumors that are poorly responsive to immunotherapy. As the beta-catenin program's biology lead, my role is to lead a multidisciplinary team to advance… Show more At FogPharma, our goal is to radically improve the treatment outcomes in cancer patients by targeting disease drivers previously believed to be “undruggable.” We believe our novel beta-catenin inhibitor will block a critical signaling pathway in cancers harboring Wnt/beta-catenin mutations and stimulate T-cell infiltration in many solid tumors that are poorly responsive to immunotherapy. As the beta-catenin program's biology lead, my role is to lead a multidisciplinary team to advance our staple peptide-based beta-catenin inhibitor to the clinic. Specifically, I work with the project team to devise a robust and efficient lead optimization workflow, including developing relevant cellular assays and selecting in vivo models. I also plan and coordinate CRO activities, including target validation, DMPK, and in vivo PK/PD/efficacy studies to support various drug discovery activities. I also collaborate with internal and external omics platforms to develop biomarker identification strategies for our new modality. In the meantime, I am contributing to the development of a high-performing biology team by directly managing 4~6 scientists and research associates. Additionally, I am also assisting the biology department head with annual goal setting and budget planning.
