πŸš€ Research Interests & Core Competencies

My work sits at the intersection of Artificial Intelligence and Biomedicine. I specialize in deploying Large Language Models (LLMs) for clinical workflows and utilizing Foundation Models for genomic sequence analysis.

  • Genomic AI: Zero-shot inference with Evo2-40B (StripedHyena architecture).
  • Clinical NLP: Automating patient recruitment with LLM agents.
  • Medical Imaging: 3D Point Cloud reconstruction & Bayesian Optimization.

πŸ”¬ Featured Projects in Biomedicine

🧬 Genomic Language Models: Evo2-40B Implementation

  • Zero-shot Inference: Deployed NVIDIA's Evo2-40B (StripedHyena 2 architecture) for unsupervised recognition of bacterial sequence features.
  • HPC Optimization: Built a large-scale parallel inference pipeline on High-Performance Computing (HPC) clusters.
  • Innovation: Implemented Windowed Inference and temperature calibration to solve instability issues in long-sequence reasoning, significantly improving robustness.

πŸ₯ LLM Agent for Clinical Trials (Parexel)

  • Patient Recruitment Agent: Led the development of an LLM-based system to extract structured data from unstructured clinical texts.
  • Performance: Designed advanced Prompt Engineering strategies and semantic matching algorithms, boosting patient-trial matching efficiency by 30%.

🦴 3D Medical Reconstruction via Bayesian Optimization

  • Algorithm Design: Developed a 3D point cloud reconstruction framework using Gaussian Processes to replace manual parameter tuning.
  • Results: Reduced geometric reconstruction error to 2.8% and improved tuning efficiency by 50% through a custom multi-objective loss function.

πŸ’Ό Professional Experience
