With Episode 200 coming up, Karl and Erum switch roles and interview each other the way they usually interview their guests. Karl shares why he decided not to become a doctor, how interviewing bands in college taught him to connect with anyone, and what he learned about storytelling during a decade in public relations before starting Messaging Lab. Erum talks about her unexpected path from studying forensic chemistry and working in pharmaceutical labs to executive coaching, joining a startup accelerator on a ship traveling around the world, and working in energy policy from the Navajo Nation to Brussels. They also discuss what waiting tables taught them about sales and humility, why early-stage startups should sometimes stay quiet until they have real traction, and why strong relationships are something AI cannot replace. Along the way, they revisit favorite moments from past guests, including Vishaal Bhuyan, Casey Lardner, Glennis Mehra, Linnea Fletcher, Elizabeth Hénaff, Phil Morle, Michael Specter, and Sabriya Stukes. Their conversation is a reminder that there is no single path into the bioeconomy.

Lisa Ressler has spent more than 35 years working in science-based businesses, including DuPont and Evonik, and now serves as Chief Commercial Officer at Amyris. In this conversation, she joins Karl and Erum to discuss where Amyris stands today, what the company learned from Chapter 11, and why returning its focus to B2B science was the right move. Lisa explains the company’s 1.5 million-liter fermentation facility in Barra Bonita, Brazil, its partnership with Wacker to develop bio-based personal care ingredients, and the simple framework she uses to decide which markets are worth pursuing. She also shares what it takes for a bio-based ingredient to move beyond higher “green” pricing and reach large-scale commercial use, making the case that strong performance is ultimately what convinces customers.

Vanessa Vongsouthi, Research Founder and Head of Bioengineering at Samsara Eco, joins host Erum on the Grow Everything Podcast to discuss how engineered enzymes and AI are making it possible to recycle textiles and plastics repeatedly. Vanessa explains how Samsara uses AI-assisted protein design and ancestral sequence reconstruction to create enzymes that break down complex polymers, including Nylon 6,6, into their original chemical building blocks. Those materials can then be returned to existing supply chains and used to create virgin-equivalent products that are indistinguishable from materials made from petrochemicals. She also shares the story behind the world’s first enzymatically recycled Nylon 6,6 jacket, created in partnership with Lululemon, and explores how Samsara Eco was built through Main Sequence Ventures’ orchestration model alongside partners such as Woolworths and the Australian National University. The conversation also looks at what a future built around distributed, local recycling infrastructure could mean for designers, manufacturers, consumers, and the global circular economy.

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 biomanufacturing: producing therapeutic medicines inside genetically engineered chicken eggs. Rather than optimizing the same mammalian cell culture systems that have defined biopharma for 50 years, Neion Bio's Raptor platform replaces complex steel bioreactor infrastructure with a self-replicating, two-input biological system — chicken feed and water in, life-saving medicines out. The conversation covers their stealth-to-commercial journey, a multi-product monoclonal antibody partnership announced alongside $11M in seed funding, the scalability and supply chain resilience advantages of egg-based manufacturing, how they navigate FDA regulation with a living bioreactor, and their North Star: dropping end-to-end production costs of monoclonal antibodies below $10 per gram — an order of magnitude that could fundamentally reshape who has access to biologics and where they're made.

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 one of the scientists who helped build NASA's synthetic biology program to talk about on-demand drug manufacturing in space, growing habitats out of fungal mycelium, engineering bacteria to pull specific metals from e-waste, and the audacious "Hell Cell" project that aims to stack every survival superpower nature has ever evolved into a single organism. If you've ever wondered what it looks like when evolutionary biology meets aerospace engineering meets materials science — with a healthy dose of iGEM undergrads and Tetris metaphors — this one's for you.

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 design, generate capex/opex estimates with uncertainty ranges (not false precision), and help teams run scenarios fast—so founders, investors, and operators can make better go/no-go decisions earlier, reduce wasteful iteration across siloed teams, and focus human expertise where it matters most.

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, why a ductile living material survives the earthquakes that shatter cinder block, and the counterintuitive truth that more mycelium does not make a stronger brick. Then things get cosmic. Chris walks through his NASA backed work growing habitats that pack down tight, fly to Mars, and unfold to grow their own radiation shielding from algae and fungi, plus the Biocycler that eats the toxins out of old houses and turns that waste into something safe. If you care about biomaterials, regenerative design, and the business models that could actually build us out of the climate crisis, this conversation will rewire how you see the walls around you.

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 ignored. Henry breaks down the real difference between model and non-model organisms, why simply culturing a new microbe can take years, and how Cultivarium is standardizing growth recipes and building an open digital platform so any researcher can work with strains that were once impossible to handle. Along the way: a fistulated cow, a spectacular failure that ultimately cracked the genetics of cement-making bacteria, extreme microbes that could free fermentation from fresh water, and Cultivarium's evolution from a Focused Research Organization into a "Frontier Research Contractor." The conversation closes on the state of American science — funding, public trust, and AI — plus the America's Living Library Act and a quick-fire round on archaea, overused buzzwords, and whether we're alone in the universe. Before the interview, Karl and Erum spill some biotech tea on "Biotech Barbie" Cathy Tie and unpack what the video game Stray gets right about engineered microbes escaping into the wild.

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 Living Library Act — a first-of-its-kind effort to sequence the DNA of flora and fauna across US national parks — Senator Young lays out a compelling vision for distributed biomanufacturing, AI-powered biological discovery, and why the US must act now in what he calls a generational tech competition with China. Karl and Erum also recap highlights from Suppliers Day hosted by the New York Society of Cosmetic Chemists, including biotech-forward exhibitors like Probiotical, Origins by Ocean, Geltor, and the unveiling of BioAtlas — the first open source map of industrial biotech.
