SPATIA

Zitnik lab's spatial-transcriptomics multimodal foundation model (ICML 2026): fuses tissue-image morphology with transcriptomic tokens via cross-attention and adds flow-matching cell-image generation, with transfer across spatial-omics tasks. Extends Harvard's scientific-FM bench (ATOMICA, ProCyon, TxAgent) into spatial biology; released with the SPATIA-MIST dataset. Sibling 2026 release: ATHENA-R1, a biomedical reasoning model.
