Our Vision

Cancer Immunotherapy has dramatically revitalized immuno-oncology, but many challenges still remain. We develop and leverage CRISPR-based platforms in primary human T cells to discover ways to engineer robust anti-tumor immunity. Our goal is to design breakthrough cell-based therapies and learn how to engineer immune cells to function in the suppressive tumor microenvironment. We use lentiviral vectors, precise knock-in by CRISPR mediated HDR and advanced experimental tools to map genetic programs that control anti-tumor immunity. The lab aims to test promising candidate perturbations in preclinical animal models of cancer immunology

Research

Engineering T cell resistance to suppressive cues

The inhibitory tumor microenvironment (TME) impedes the therapeutic benefit of engineered cell therapies. We aim to chart the factors that mediate immunosuppression using loss-of-function genetic screens under suppressive conditions. We test how CRISPR perturbation of genes that mediate suppressive signals can improve T cell function in vitro and in preclinical animal models. Overall, this work will discover key genetic programs that mediate human T cell dysfunction in the inhibitory TME.

Polyclonal anti-tumor immunity by engineered T cells

T cell therapies based on single antigen specificity may lead to tumor escape by antigen-loss or immunoediting. Polyclonal anti-tumor responses may overcome these limitations. We aim to engineer synthetic TCR repertoires in primary human T cells using knock-in of functional TCR sequences to define relationships between T cell specificity and function. This innovative work will reinvigorate anti-tumor responses by engineered polyclonal T cells directed against tumor antigens.

Self-reactive T cells in homeostasis and disease

Immunotherapies that rely on tolerance breakdown often result in immune related adverse events and highlight the high priority unmet need to understand the hidden self-reactive T cell repertoire. We leverage our discovery of genetic factors that tune TCR responsiveness to study pre-existing self-reactive T cells in healthy individuals. We aim to define the role of self-reactivity in humans with implications for autoimmunity and cancer.
