Experience

VP, Engineering & Research (Founding Team) | Osmo
  • I started as the first research engineer, grew into the first engineering manager, and now lead engineering and research as VP. Our 10+ person team of software engineers, ML researchers, and human-data experts takes frontier AI-for-science from prototype to production at this post-Google spin-out.
  • AI for Science: Worked with perfumers, lab scientists, and annotators to ship cost-and-safety optimization for our formula model, anchoring a multi-million-dollar CPG enterprise deal. Built a GNN end-to-end that predicts intensity from molecular structure, significantly lifting our ingredient-discovery hit rate. Worked with analytical chemists to "teleport" a physical plum scent, translating GC-MS signatures into digital profiles and validating the technology end-to-end.
  • Hands-on Agentic AI: Architected Studio, an agentic platform that turns brand briefs into formulas. Frontier LLMs, fine-tuned with SFT and RL, orchestrate our perfumery tools and chemical data through a RAG-like system. An active-learning loop with perfumers feeds an eval stack that lifts model quality release-over-release.
  • 0-1 Multimodal ML Stack: Built the post-Google ML stack from scratch (PyTorch, GCP, W&B), connecting olfactory data across molecular structures, fragrance materials, analytical instrument signals, human perception labels, and visual concepts. Shipped training-data pipelines, evaluation frameworks, and deployment infrastructure for the team to build on.
Student Researcher | Google
  • Olfactory ML: Built receptor binding and metabolic activity models that catalyzed Osmo's $60M spin-out. The work led to one utility patent and four publications featured in major news outlets.
  • Generative ML for Cell Imaging: First-authored a GAN approach to batch-effect correction in high-content cellular imaging, published in Bioinformatics and open-sourced as part of Google's TF-GAN library.
  • Genomics & Structural Variants: Built ML-based filtering for structural variant calling, plus a ~100× faster read-alignment method, filed as a utility patent.
Intern | DeepMind
  • AlphaFold Team: Worked with the team behind AlphaFold2 on protein-folding research. Built representation learning models for biological structure prediction in JAX, on top of the AlphaFold2 codebase, at foundation-model scale.
Software Engineering Intern | Uber
  • [2017] Sensor & Machine Learning: Built a CRF variant to infer Uber Eats delivery events from mobile sensor data. Won 1st place at Uber's internal ML poster session.
  • [2016] Mobile Dev. & Engineering: Built a web-based forensics tool for mobile UI testing that synchronized logs with video timestamps, cutting internal developer debugging time by ~50%.
