We study how disease micro-environments shape human health by integrating multimodal omics with digital pathology. By linking spatial transcriptomics and single-cell genomics to tissue architecture in clinical imaging, we capture how cells interact within complex tissues.

We develop robust, interpretable machine learning methods to analyze large-scale patient data. Our goal is to identify spatial and molecular patterns that inform prognosis, treatment response, and disease risk. By connecting molecular activity with tissue organization, we aim to discover clinically actionable biomarkers and therapeutic targets that advance precision medicine and improve public health.

We are an interdisciplinary group and welcome trainees from biomedical and quantitative fields.

Research

We develop computational methods for multimodal biology, linking cell-state dynamics, tissue morphology, and spatial molecular measurements.

Cell-state dynamics

cellDancer

A deep-learning framework for RNA velocity with cell-specific kinetics. By estimating local velocities and relaying them across neighboring cells, cellDancer improves inference of multi-lineage cell-state transitions.

Visual-omics bridge

Loki

A visual-omics platform built from OmiCLIP to align H&E histology with spatial transcriptomics. It turns paired image-omics data into a shared representation for annotation, retrieval, decomposition, and expression prediction.

Spatial tissue interpretation

Thor

A platform for cell-level spatial transcriptomics and histology. Thor uses anti-shrinking Markov diffusion to refine spot-level measurements toward cell-level tissue maps, paired with interactive whole-slide visualization through Mjolnir.
