Graph representation learning
Learning from relationships, not just individual observations. I study graph-based and semi-supervised methods that use network structure when labels are scarce.
How can multiple relationships support learning when supervision is limited?
Explainable biomedical AI
Connecting neuroimaging, plasma proteomics, and biological knowledge to study disease heterogeneity and interpretable biomarkers.
How can biological structure make multimodal predictions more interpretable?
Learning across domains & time
Transferring information between heterogeneous populations, measurement settings, and time points while preserving useful differences.
What should be shared—and what should be preserved—across domains?
