Nellie Kolon

Founding Engineer at Deleon Technologies

I’m a biochemist and biomedical engineer. At Deleon, I lead R&D on the lab side of an AI research company and work between the lab and our ML engineers, turning chemistry into data our models can learn from. Before that, I spent three years developing lipid nanoparticle medicines at Eli Lilly.

Before Deleon

Earlier roles

2024 – 2025

Graduate Student Researcher

Georgia Institute of Technology, Ackun-Farmmer Lab

The lab develops ways to retrain immune cells to stop attacking the body in multiple sclerosis.

  • Rethought the lab’s polymeric nanoparticle synthesis using recent literature, updating long-standing protocols and cutting synthesis time from 10 hours to 30 minutes.
  • Designed peptide-targeted nanoparticles to reprogram T cell responses.
  • Co-wrote a review in Biomaterials Science, including the sections on lipid-based materials.
  • Mentored an undergraduate researcher, training him in nanoparticle synthesis and in vitro techniques and helping him earn a research scholarship.

2021 – 2024

Senior Research Associate, Genetic Medicine

Eli Lilly and Company, Cambridge, MA · promoted from contractor

  • Helped build a fully automated lipid nanoparticle synthesis and characterization platform with Lilly’s automation engineers. The team went from about 5 formulations a day by hand to more than 100 a week, and the platform is still in use.
  • Generated the data for an ML model of how lipid chemistry affects nanoparticle formation and efficacy, and used it to narrow down candidates for mouse and non-human primate studies.
  • Ran all hands-on experiments on a two-person team led by my supervisor, programmed Hamilton liquid handlers for the characterization assays, and presented results to teams in Indianapolis and San Diego.
  • Used Design of Experiments to map how design parameters and lipid components interact, and scaled formulation from 100 µL–1 mL batches up to 1 L for non-human primate studies.

2019

Analytical Chemistry Co-op

Takeda Pharmaceuticals, Cambridge, MA

  • Ran purity, stability, and solubility assays on oncology drug candidates and presented an in vivo ELISA study to 50+ scientists.
