Title: Scaling Biological Representation Learning and Experimental Design
Abstract: High-throughput cellular assays now generate data at a scale that enables highly predictive phenotypic models, yet our ability to extract mechanistic insight from these systems remains limited. I will discuss our recent work on scaling masked-autoencoders on microscopy images and show that the resulting representations are surprisingly effective at recovering known biological structure. I will then describe our work on mechanistic interpretability techniques for decomposing these embeddings into interpretable, biologically aligned features. Finally, I will discuss experimental design in the context of these large models. I will formalize a hierarchy of interaction models—ranging from scalar viability readouts to full distributional predictions—to characterize when single-perturbation information is sufficient to generalize to combinations. This perspective leads to an efficient experimental-design strategy: treat non-interaction as the default, use additive composition to generate predictions, and focus measurements on identifying failures of this assumption.
