Summary
Zachary is using machine learning to predict the best combination of ingredients to create a media that optimizes muscle cell growth. The media used for growing muscle cells is made up of several ingredients, but some of those ingredients may be better for cell growth than others. Conventional techniques involve changing one ingredient at a time, but Zachary’s lab uses an artificial neural network to learn from experiments and predict the best combination of ingredients.

Why This Matters
Zachary’s work will help accelerate breakthroughs in the field of cellular agriculture by using machine learning to speed up the research process. In the future, his program could be used to create formula best suited for any purpose a future researcher would hope to obtain.
Outcomes
Zachary identified and explored, both experimentally and computationally, major advantages that machine learning and Bayesian optimization methods have over traditional design-of-experiments methods in quickly designing cell culture media for rapid product deployment. A Bayesian multi-assay approach to optimizing media to increase cell growth and reduce cost was particularly effective, and resulted in significantly more productive and less costly serum and serum-free media for cellular agriculture applications.
