What happens when an evolutionary biologist and an aerospace engineer both arrive at the same conclusion — that the future of drug manufacturing isn't steel, it's biology? In this episode, Karl Schmieder and Erum Azeez Khan sit down with Sam Levin (Co-Founder & CTO) and Dimi Kellari (Co-Founder & CEO) of Neion Bio to unpack one of the most counterintuitive ideas in modern biomanufa...

What does it actually take to keep humans alive on Mars? Not the SpaceX version — the biology version. Dr. Lynn Rothschild, research scientist at NASA Ames and adjunct professor at Brown and Stanford, has spent decades at the intersection of astrobiology and synthetic biology, and her answer is both elegant and radical: life itself is the technology. On this episode, Karl and Erum sit down with on...

Recorded live at New York Tech Week, Karl and Erum sit down with Brenton Alexander (CTO at Roebling) to unpack one of the biggest bottlenecks in scaling “biology as technology”: figuring out what it  really  takes to design and finance physical infrastructure. Brenton walks through how Roebling uses AI alongside deterministic engineering models (physics/thermodynamics) to accelerate early facility...

What if the building you live in could be grown instead of built, feed people while it goes up, and lock away carbon for a century? Architect Chris Maurer of Red House Architecture and MycoHab joins Karl and Erum to explain how he turns 12 tons of invasive bush into mushrooms that feed a community and mycelium blocks that test stronger than concrete. He breaks down the now famous sledgehammer test...

Most of biotech runs on a tiny handful of "model" organisms — E. coli, baker's yeast — while millions of wild species sit unstudied in what scientists call microbial dark matter. In this episode, Karl and Erum sit down with Henry Lee, co-founder of Cultivarium, to explore why the future of synthetic biology depends on learning to grow, study, and engineer the organisms we've igno...

Senator Todd Young joins the Grow Everything podcast to discuss the critical intersection of biotechnology and national security, sharing how his military background, Indiana roots, and role as chairman of the National Security Commission on Emerging Biotechnology shaped his understanding of the bioeconomy as a strategic imperative. From DARPA's shelf-stable powdered blood to the America's...

Ricky Cassini, CEO of Michroma and a former logistics professor turned biotech founder, breaks down why replacing synthetic food dyes is harder than it sounds—and why fermentation-based colorants can outperform both petrochemical dyes and many plant-based “natural” extracts. The conversation covers the core technical constraints that matter to food companies (thermal stability, pH stability, color...

Recorded live during DC Climate Week, the Grow Everything team sits down with investors Veronica Breckenridge, Jillian Chase, and Michael Luciani to unpack the real state of the US bioeconomy race with China, why fermentation and scale-up capacity are a persistent bottleneck, and how policy, non-dilutive funding, and better founder execution can close the gap. The panel argues that the US still le...

Karl and Erum talk with Jesse Adler, founder of Pitri, about why color is not just aesthetic, but chemical, biological, and deeply tied to human and environmental health. Jesse traces their path from biomolecular science and biodesign into building fungal pigments that can replace synthetic and animal-derived colorants, starting with the beauty industry as a high-margin, ingredient-driven entry po...

In this replay episode of Grow Everything, Karl and Erum catch up after recent travel, reflect on a standout mainstream biotech article about biology reshaping the global chemical industry, and discuss why “tissue-on-a-chip” experiments in space matter for long-duration missions. They then kick off a deeper dive into bio-based dyes by revisiting their interview with Orr Yarkoni, co-founder and CEO...
