Research Experience

  • Apr 2025 – Sep 2025

    Cambridge, UK

    Protein Substructure Alignment via Optimal Transport
    University of Cambridge & SJTU
    • External collaboration | Supervisors: Prof. Pietro Liò & Prof. Liang Hong
    • Developed PLASMA, an optimal-transport module that adds fast, highly accurate local-substructure identification to protein representation models with minimal or no training. Accepted as a poster at ICLR 2026.
    • Evaluated seven protein-language-model backbones across the VenusX motif, active-site, and binding-site tasks, improving ROC-AUC by 10–30% across all backbones and tasks.
    • Used PyMOL case studies to show that retrieved substructures were structurally similar rather than artifacts of sequence similarity.
  • Oct 2024 – Sep 2025

    Cambridge, UK

    Hierarchical Protein Representation Learning
    University of Cambridge
    • Research Assistant | Supervisor: Prof. Pietro Liò
    • Developed TCPNet, an SE(3)-equivariant topological neural network that jointly learns residue- and secondary-structure-level protein features without losing geometric information.
    • Received the Highly Commended M.Phil Project Prize 2024–2025 from the Department of Computer Science and Technology.
    • Improved performance by 5% on average across three protein-representation tasks when only structural features were provided.
  • Feb 2025 – Sep 2025

    Cambridge, UK

    Multi-Omics Integration with GNNs
    University of Cambridge
    • Research Assistant | Supervisor: Prof. Pietro Liò
    • Used a heterogeneous graph network to embed single-cell RNA, protein, and ATAC modalities into a shared latent space for cell clustering.
    • Trained on BM-CITE and LUNG-CITE in under an hour on a laptop GPU, with ARI 3% and NMI 2% below the statistical method MOJITOO.
  • Oct 2024 – Jan 2025

    Cambridge, UK

    Graph-based Pain Estimation from Facial Expressions
    University of Cambridge
    • Research Assistant | Supervisor: Prof. Hatice Gunes
    • Presented at the IJCAI 2025 MiGA Workshop.
    • Proposed GraphAU-Pain, combining a ResNet-50 backbone with graph-based facial-action-unit representations for interpretable pain-intensity estimation.
    • Developed a transfer-learning strategy for domain differences and missing annotations, improving AU-occurrence F1 by 30% on UNBC.
  • May 2023 – Jun 2024

    London, UK

    Readmission Prediction with Remote Patient Monitoring Data
    University College London
    • Research Assistant | Supervisor: Prof. Ivana Drobnjak
    • Collaborated with UCL Hospital clinicians on a SQL data pipeline, clinical feature engineering, and interpretable ML models (ROC-AUC 0.79 ± 0.03) with SHAP analysis.
    • Designed patient-independent stratified bootstrapping for 55 patients with class imbalance, preventing leakage and improving the reliability of deployment estimates.

Industrial Experience

  • Sep 2025 – Present

    Beijing, China

    AI Scientist & Timeseries Generation/Prediction
    Sapient Intelligence
    • ML Research Scientist
    • Developing Praxit, an autonomous AI-scientist framework with DAG-based execution lineage for solution provenance; achieved roughly 30% higher performance at 10% of the cost of Claude Code with Opus on Karpathy's AutoResearch prompt.
    • Showcased Praxit at AI4 2026 through live booth demonstrations and conversations with prospective customers and collaborators.
    • Generating synthetic time-series data and developing HRM-based forecasting models for weight-management applications.
  • Jul 2024 – Sep 2024

    Hefei, China

    Healthcare LLM Knowledge Distillation
    Xunfei Healthcare Technology
    • Intern ML Researcher
    • Built a teacher-LLM knowledge-distillation pipeline that synthesized medical instructions and improved Xiaoyi's instruction-following accuracy from 34% to 82% through supervised fine-tuning.
  • May 2023 – Aug 2023

    Shanghai, China

    RAG-Based Financial Intelligence System
    Luojin Data Information
    • Intern ML Engineer

  • Sep 2022 – May 2023

    London, UK

    Low-cost AI Chatbot Generation System for Hospitals
    National Health Service
    • Intern Software Engineer
