In this episode of Galaxy Balance, Cory Smith is joined by Marc Güell, a synthetic biologist working at the frontier of genome engineering, AI-driven biological design, and translational therapeutics. Marc's work spans programmable genome integration systems, synthetic evolution, and the development of biological tools that extend far beyond what natural evolution has produced.

From his early training in chemistry and engineering to his time in the Church Lab at Harvard and now leading a research group in Barcelona, Marc's career reflects a consistent focus on building new biological technologies. The conversation explores how generative AI is reshaping genome writing, why engineering principles matter in biology, and what it takes to translate deep-tech synthetic biology into real-world applications.

We also discuss the founding of Integra Therapeutics, engineering the skin microbiome as a therapeutic platform, and how imagination influences real life science.
