Research Interests
I develop robust and trustworthy learning methods for modern biomedical data and beyond. My research draws from the following different domains.
Robust and Trustworthy Machine Learning: backdoor attacks, adversarial attacks, label noise, uncertainty.
Biomedical informatics: digital pathology, multi-omics data analytics, spatial and topological analysis of tissue micorenvionment.
Topological data analysis: learning with topological features, topology-informed image segmentation and analysis.

New!!
Two papers accepted by CVPR 2025!
Congratulations to Meilong and Ani for getting their papers accepted by the top CV conference CVPR.
Meilong's paper proposes the first topology-aware diffusion model for cell layout generation. Ani's paper proposes a novel gene prediction method based on spatial transcriptomics data, using a multi-faceted graph GNN that is well motivated by the biology.

Three papers accepted by ICLR 2025!
Congratulations to Saumya, Weimin, and Chris for getting their papers accepted by the top ML conference ICLR.
Saumya's paper proposes the first topology-aware diffusion network, generating images with explicit topological constraints (thus correct object counts and correct holes). Weimin's paper tackles backdoor attack problem for vision-language models, especially for out-of-distribution data. Chris' paper studies the geometry of long-tail data representation, and proposes a new solution via feature generation.

One paper accepted to JMLR!
Congratulations to Zuoyu for his paper being accepted by the top ML journal JMLR.
Zuoyu's paper discusses in details the theoretical foundation and applicaiton benefit of incoporating topological features (i.e., persistent homology) into graph neural networks.
