Computational Oncology / Tumor Immunology

Xin Xiong Biotechnology Undergraduate at Sichuan University

I work at the intersection of tumor microenvironment analysis, single-cell and spatial transcriptomics, and experimentally grounded bioengineering. My current portfolio combines network-based inference, signaling interpretation, and wet-lab training to study how cellular communication shapes cancer development and translational design.

Academic Coordinates

Current Positioning

01 / Computational Oncology

Cell-cell communication as a systems problem

My main computational thread studies tumor ecosystems through single-cell and spatial transcriptomic data, with emphasis on recurrent signaling circuits and conserved communication hubs.

02 / Methods

Inference grounded in interpretable pipelines

I use CellChat, NicheNet, CoVarnet reimplementation, spatial co-localization logic, and topology-aware centrality analyses to move from raw data toward biologically defensible hypotheses.

03 / Experimental Translation

Mechanistic follow-up beyond pure computation

My work is not limited to analysis. I also train in mutagenesis, lentiviral delivery, protein purification, and live-cell assays to connect predictions with measurable phenotypes.

04 / Research Style

Academic clarity with cross-disciplinary mobility

I enjoy projects that move across code, literature, and wet-lab execution, especially when they require translating between biological mechanisms and computational structure.

Recent Milestones

2024 - 2026

Pan-cancer signaling atlas in tumor microenvironments

Standardized scRNA pipelines across 10+ cancer types, integrated ligand-receptor inference, and identified conserved hub cell populations linked to pathway-level regulatory programs.

TP53RK functional-mode determination

Compared phosphorylation-dependent versus KEOPS-complex-dependent functions using mutant design, lentiviral transduction, dTAG-mediated degradation, and Incucyte-based phenotyping.

iGEM TasAnchor whole-cell immobilization platform

Built a modular Bacillus subtilis adhesion scaffold with genome editing, SpyTag/SpyCatcher design, IPTG-induced protein expression, purification, and functional integration on material surfaces.

Advanced research training at PKU and Westlake

Expanded systems biology, genomics, and experimental research exposure through Peking University summer training and Westlake University academic programs.
