Postdoctoral Fellow, Lu Lab - Immune Aging

Calico • South San Francisco, CA

7h • $95,000 • Onsite

About The Position

Calico (Calico Life Sciences LLC) is an Alphabet-founded research and development company whose mission is to harness advanced technologies and model systems to increase our understanding of the biology that controls human aging. Calico will use that knowledge to devise interventions that enable people to lead longer and healthier lives. Calico’s highly innovative technology labs, its commitment to curiosity-driven discovery science and, with academic and industry partners, its vibrant drug-development pipeline, together create an inspiring and exciting place to catalyze and enable medical breakthroughs. The Calico Postdoctoral Fellowship Program We are seeking ambitious early career scientists to join us in our mission to increase our understanding of the biology that controls human aging. This is a unique opportunity for individuals to distinguish themselves in aging research, deepen scientific training, and develop research independence. The Postdoctoral Fellowship is a fixed-term educational assignment (three years with a potential fourth year extension) with rolling start dates. Postdoctoral Fellows are fully integrated into Calico's labs and community. The program is designed to train individuals to become independent investigators in an academic or industry setting upon successful completion of the assignment. Fellows will receive regular feedback and guidance from their mentor(s) and participate in a formal annual review process to review project progress and individual performance and provide career coaching. T cells play a pivotal role in the adaptive immune system by distinguishing foreign pathogens from self-antigens with exceptional sensitivity. However, as humans age, this precise discrimination wanes. Aged T cells respond poorly to external threats while becoming increasingly reactive toward the body’s own tissues. Our group is dedicated to deciphering the fundamental mechanisms by which aging impairs the T cell’s function, with the ultimate goal of restoring immune precision and resilience in older populations. A potential driver of T cell aging is age-related thymic involution, which alters thymic selection processes and compromises both the quantity and quality of new T cell production. In response to the diminished output from an involuted thymus, existing naïve T cells undergo homeostatic proliferation, and eventually develop functional exhaustion. We are interested in decoding the intrinsic and extrinsic factors that regulate T cell aging. We envision that by modulating T cell sensitivity, we can rejuvenate T cell function, lower the incidence of autoimmunity and cancer, and extend the healthspan of older individuals. We welcome proposals that address core questions of T cell aging. We are seeking researchers who are intellectually fearless, naturally curious, and eager to tackle complex questions through rigorous experimentation. Ideal candidates will be collaborative team players who thrive in a multidisciplinary environment and are committed to pushing the boundaries of immunology and aging research.
