Technology
Computational Biology & Transcriptomics
Computational analysis of single-cell, single-nucleus and spatial transcriptomics forms part of our scientific capabilities. These approaches connect cell identity, gene expression, regulatory activity and spatial context to support research questions.
Methods are selected according to data structure and the biological question. Analysis spans R and Python, with attention to dataset compatibility, parameter transparency and reproducibility.
Scientific capabilities
- Single-cell & single-nucleus RNA-seq
- Quality control, normalization, dimensionality reduction, clustering, cell-type annotation and differential expression. Trajectory inference, RNA velocity and CellRank support analysis of cell fate, alongside regulatory network and cell–cell communication analysis.
- Spatial transcriptomics
- Spatial data processing, domain identification, deconvolution, spatial autocorrelation, spatially variable gene detection and spatial cell–cell communication. Cell-type expression profiles are used to estimate abundance proportions within spatial units and map single-cell subtypes to spatial coordinates.
- Cross-modality integration
- Integrating the transcriptomic depth of single-cell and single-nucleus data with spatial context through label transfer, reference-based deconvolution and cross-platform validation.
- Cell–cell communication
- Multi-method aggregation of ligand–receptor interaction scores across cell-type pairs. In spatial data, proximity weighting is used to assess whether inferred signaling is supported by neighboring cell locations.
- Regulatory network analysis
- Inference of transcription factor activity and gene regulatory networks, projected into spatial coordinates to connect regulatory activity with tissue context. Virtual gene knockout is used to predict downstream effects of perturbing specific regulators.
Computational approaches
From reference construction to integrated interpretation, the analysis is shaped by the research question and the data available.
- Reference construction & annotation
- Standardization, dimensionality reduction and graph-based clustering identify cell populations. Marker-based annotation is interpreted in the relevant tissue and disease context.
- Spatial validation & consistency
- Spatial autocorrelation assessment, comparison of temporal trends between platforms and visualization of ligand–receptor co-expression in spatial coordinates.
- Public data & cross-dataset integration
- Retrieval and analysis of public data from GEO, CNSA and STOmics DB. Integration across platforms and batches is preceded by assessment of model consistency, time-point overlap, tissue-region compatibility and data scale.
- Computational strategy & analysis workflows
- Analysis strategy is designed around the biological question and dataset compatibility. Workflows include reusable code, parameter documentation and reproducibility materials for research collaboration.
