Selected Projects

CLAW-MRM Figure

CLAW‑MRM

End‑to‑end automation for lipidomics MRM: worklist generation, QC agents, parsing, stats, and visualization.

  • Automates lipid profiling—from parsing raw binary (.d) files into organized pandas DataFrames to annotation using custom MRM transition databases and robust statistical analysis.
  • Applies trimmed mean of M-values (TMM) normalization for lipid load correction and generalized linear models (GLMs) in edgeR for overdispersed count data analysis, providing a robust statistical framework for lipidomics.
  • Integrates LIGER (lipidome gene enrichment reactions) to connect lipid expression with gene activation and suppression patterns, highlighting biologically relevant pathways.
  • Incorporates a language user interface (LUI) with interactive artificially intelligent (AI) agents, providing a conversational way to perform statistical and bioinformatics workflows.
  • Applied this pipeline to Alzheimer’s disease mouse models, profiling nearly 1,500 MRM transitions across 11 lipid classes, and revealing metabolic pathways enriched in differentially expressed lipids.

Agentic Chip-based nanoESI-MS/MS Figure

Automated Agentic Chip-based nanoESI-MS/MS

An LLM-driven AI agent framework for chip-based nanoESI-MS/MS automates experimental and analytical tasks while remaining accessible, adaptable, and informed by both literature and lab-specific knowledge. Manuscript in preparation.

  • AI-driven automation: Integrates LLM reasoning with tool-based execution to autonomously handle worklist creation, QC, data conversion, visualization, and literature retrieval.
  • Accessible workflows: Eliminates coding barriers, enabling non-specialists to run end-to-end chip-based nanoESI-MS/MS experiments independently.
  • Adaptive and evolving framework: Modular design preserves lab knowledge, integrates literature, and flexibly updates with new methods and technologies.
