Laboratory Technician (Feb 2023 – Mar 2026) · Lead Center Scientist & Team Lead, CASBR (Jul 2023 – Mar 2026) · Research Assistant (Aug 2025 – Mar 2026)

• Studied metabolism across cancer, neurodegeneration and rare metabolic disease with MALDI timsTOF mass spectrometry imaging: spatial metabolomics, lipidomics and glycomics (glycogen and N-glycans), on fresh-frozen and FFPE tissue.
• Operated and maintained the Bruker timsTOF and coordinated service visits with Bruker and HTX.
• First author on methods for mass spectrometry imaging of the cochlea (J Am Soc Mass Spectrom, 2026) and of the glycome (J Vis Exp, 2025); one of four co-first authors on MetaVision3D, an AI-driven 3D map of the brain metabolome (Nature Metabolism, 2025).
• Developed Vision (in-house, unpublished), an all-in-one platform combining Sami (Nat Commun) and MetaVision3D (Nat Metab) for analysis, visualization and spatial UMAP clustering of high-dimensional spatial omics data.
• Coordinated workflows for 250+ CASBR projects, wrote 10+ standardized protocols, and trained and led a team of 8 researchers.
• Ran day-to-day lab operations: purchasing and spend tracking, vendor quotes, instrument service contracts, material transfer agreements, sample shipping with collaborators worldwide, and tracking for 6,000+ samples.
• In vivo mouse work under approved protocols: IP, tail-vein and oral-gavage dosing; blood collection; dissection and tissue harvest; behavioral testing; viral-vector lung tumor induction; helped maintain breeding colonies (breeder setup, weaning, Transnetyx genotyping).
• Generated spatial multiomics data for collaborations with groups worldwide, contributing to 19 publications and preprints.
