OxTalks is Changing
OxTalks will soon be transitioning to Oxford Events (full details are available on the Staff Gateway). A two-week publishing freeze is expected in early Hilary to allow all events to be migrated to the new platform. During this period, you will not be able to submit or edit events on OxTalks. The exact freeze dates will be confirmed as soon as possible.

Dissecting complex immune disease mechanisms through context-specific gene regulation and T cell morphodynamics
This is a hybrid event - with the speaker attending in-person and viewable on Teams.
Revealing the cellular impact of immune-mediated disease-associated (IMD) variants requires measuring their effects within the dynamic gene expression and phenotypic programmes that shape immune cell function. In this seminar, I will present our recent work, which resolves context-specific eQTLs across T cell activation states and reveals how polygenic IMD risk converges on discrete, activation-dependent gene programmes. These analyses uncover regulatory axes that link genetic architecture to effector function and disentangle proliferation, differentiation, and metabolic rewiring to pinpoint key contexts in which disease variants exert their impact.
I will then introduce TGlow, our high-content imaging platform that profiles T cell morphology at scale, enabling us to capture phenotypes beyond transcript abundance. By quantifying morphodynamic trajectories during activation and exhaustion, TGlow provides an orthogonal layer for studying variant-relevant biology, allowing us to map how genetic- and drug-induced perturbations, reshape T cell states. Together, these approaches outline our strategy for decoding IMD variant effects through large-scale multimodal profiling of gene regulation, cellular programs, and functional phenotypes.
