Field of Research

Computational biology/bioinformatics with emphasis on spatial transcriptomics, proteomics, and immunosequencing using Pixel‑seq and an immune receptor‑focused multimodal expansion (“Immuno Pixel‑seq”). Work includes NGS data processing, spatial barcode mapping, single‑cell & spatial analysis, and cell segmentation in brain, tumor, and other tissues.

Work includes NGS data processing, spatial barcode mapping, single‑cell & spatial analysis, and cell segmentation in brain, tumor, and other tissues.

To build and operate robust, reproducible pipelines that transform raw sequencing + barcode map into high‑quality, spatially resolved single‑cell datasets; to deliver disease‑focused analyses that advance mechanistic discovery and translational hypotheses (e.g., tumor microenvironment, neuroanatomical circuits).

• End‑to‑end data processing (BCL/FASTQ → QC → counts) – 20%
• Demultiplexing, adapter/quality trimming, UMI handling, alignment/quantification; generation of Multi
  
  QC reports and run manifests.
• Spatial barcode mapping & registration – 15%
• Build/validate barcode→(x,y) maps for Pixel‑seq; error correction; join gene/protein counts to spatial coordinates; QA of mapping rates.
• Segmentation & QC – 20%
• Apply/benchmark nuclei or whole‑cell segmentation (e.g., Cellpose/Star Dist/SAM); maintain curated masks and QC thumbnails.
• Downstream single‑cell & spatial analysis – 20%
• Create annotated data objects (e.g., Ann Data/Seurat); normalization, clustering, label transfer; spatial neighborhood/domain analysis; multi‑omic modeling for RNA+protein where applicable.
• Pipeline automation & reproducibility – 10%
• Implement/maintain Snakemake/Nextflow workflows with containers (Apptainer/Docker), CI tests, and clear documentation.
• Project support, collaboration & reporting – 7%
• Prepare figures/tables; concise analysis memos; contribute to methods sections.
• Light server/environment maintenance & upgrades (Dev Ops‑lite) — 5%
• Build and update containerized analysis environments, maintain conda/uv environments.
• Dev Ops‑lite & data stewardship – 3%
• Maintain analysis environments/containers; basic SLURM job scripts; coordinate with IT on storage/backup hygiene.
