Reading this session¶
The smallest peer-reviewed session, and the most methodologically classical — graphs, diffusion, random walks, knowledge graphs. Two things are worth noting.
Agentic AI reaches network biology. Ke Chen et al.'s Discovery of Disease Relationships via Transcriptomic Signature Analysis Powered by Agentic AI (the GenoMAS system) runs across roughly 1,300 disease-condition pairs. Together with the two LLM-agent papers in S2 and MedAgentBench v2 in S4, this makes four agentic papers across three sessions — the clearest signal at PSB 2026 that agents have moved from demo to method.
Provenance and interpretability for network algorithms. Tasnina et al.'s Provenance Tracing in Network Diffusion Algorithms asks which inputs actually drove a diffusion result — the network-biology version of the interpretability question the corpus keeps asking of foundation models.
The rest is solid applied work: Zhou et al.'s REPEL perturbs embeddings to improve protein-function learning; Krishnan et al. retrieve sparse perturbations for steady-state control; Orlenko et al. use a random-walk framework for Alzheimer's therapeutic targets; Rajagopalan et al.'s DRIVE-KG builds heterogeneous knowledge graphs over the Penn Medicine BioBank and Regeneron Genetics Center data for variant–phenotype discovery in understudied diseases.
Worth noting: organizer Joshua Welch is a single-cell integration methodologist (LIGER), but no single-cell paper landed in this session — see Themes for where the single-cell material actually went.
