Kevin E. Stone

I build process models from lab data, and I lead the scientists who use them to make decisions on Merck's biologics pipeline.

Over the past decade at Merck I've contributed to eight approved medicines. I started as a reaction engineer on doravirine, carrying steps from development through filing and launch, and over the years added high-throughput experimentation, kinetic modeling, Bayesian optimization, and machine learning to how I work.

Today I lead a team of 10 bioprocess modeling scientists working with biologics process development on cell culture models, bioreactor scale-up and scale-down, chromatography, and filtration. I still write a lot of the code myself, including obsidian and GARNET.

  • Building a full-service bioprocess modeling group for biologics drug-substance development.
  • Using models to guide upstream process characterization and bioreactor scale-up, with new work in scale-down and filtration modeling.
  • At the piano, still working through Liszt.
