Steve Oh joins David Brühlmann to share how XT Thrive®—a next-generation cryopreservation solution draw...

Arctic fish survive in waters that would freeze most life solid. Not because they tolerate ice, but because their biology prevents crystals from forming in the first place. That same principle, translated into synthetic peptide chemistry, is now showing performance data that DMSO cannot match. Part 2 is where the science becomes practical. Steve Oh spent 22 years at Singapore's A*STAR accumul...

Why do CDMOs keep building bigger stainless-steel facilities while their margins erode and Asian competitors undercut them on price? And what happens when big pharma decides to stop outsourcing altogether? The business model that sustained the industry for two decades is under pressure from every direction, and for many CDMOs, standing still is no longer a neutral position. In Part 2, Juergen Mair...

Meet Juergen Mairhofer, CEO of enGenes Biotech GmbH and a scientist with a rare dual fluency in molecular biology and bioprocess engineering. He's not just optimizing at the margins. He's devised a proprietary E. coli platform that radically stabilizes ge...

For many biotech innovators, high-throughput screening platforms promise faster discoveries and streamlined workflows. Yet beneath the surface, the reality is more demanding, requiring hands-on expertise, careful assay design, and a sharp understanding of microbial physiology to avoid mistakes that become expensive to fix downstream. David Brühlmann continues his conversation with Sebastian Blum,...

Why do so many promising biotech ideas stall long before they reach the clinic or marketplace? For many, the answer lies hidden in the earliest phase of bioprocess development: upstream processing. It’s where strain selection, media optimization, and culture conditions set the stage for everything that follows. Yet, the smallest missteps here can snowball into expensive roadblocks downstream. This...

For years, mammalian cells and microbial systems have dominated the biotech landscape, shaping the economics and access to life-saving biologics. Yet, in countries where capital and infrastructure are limited, those gold-standard systems bring hefty price tags and daunting complexity. The answer isn't bigger bioreactors; it's alternative biomanufacturing approaches, such as molecular far...

Waranyoo Phoolcharoen, Co-Founder and CTO of Baiya Phytopharm and Professor at Chulalongkorn University in Bangkok, leads the charge in molecular farming in Thailand, pioneering a shift from traditional biomanufacturing toward using whole pla...

Picture a new bioprocess automation project: ambitious, expensive, and packed with promise. But after months of development, your team discovers a flaw that could have been caught with a simple mockup and a few sticky notes on a whiteboard. This episode confronts the real cost of skipping discovery, premature automation, and the myth that faster engineering always means faster solutions. Anthony C...

Many bioprocess automation projects fail, not because the technology is wrong, but because no one clearly defined the problem before buying the robot. In this episode, David Brühlmann sits down with Anthony Catacchio, CEO of Product Insight, to explore why rigorous system design and honest problem definition matter more than any individual technology, and how industrial robotics expertise translat...

How solid is your CMC foundation—and what happens if it cracks under pressure? David Brühlmann welcomes Henri Kornmann, former Head of Biologics Innovation Centre at Ferring Pharmaceuticals. From junior CMC scientist at Merck to leading Ferring Pharmaceuticals' first gene therapy approval for bladder cancer, Henri has moved repeatedly between CMC development, GMP manufacturing, and due dilige...

Seventy percent of FDA Complete Response Letters have a CMC root cause. Most of those failures trace back to decisions made years earlier. Decisions that felt minor at the time and proved impossible to fix later. Henri Kornmann has spent two decades making those decisions the right way. From junior CMC scientist at Merck to leading Ferring Pharmaceuticals' first gene therapy approval for blad...

What if the future of sustainable manufacturing required no sugar feedstocks, generated minimal waste, and operated carbon-neutral from day one? Ocean-derived cyanobacteria are making this possible—but the path from promising strain to profitable business is littered with synthetic biology casualties. This episode reveals the strategic decisions that separate winners from failures. In Part 2, Tim...

The chemicals industry remains locked into carbon-intensive, fossil-based manufacturing. Even engineered microbes like yeast or E. coli depend on expensive sugar feedstocks while generating significant waste. What if a photosynthetic organism could eliminate those constraints entirely—while commanding premium pricing as "ocean-derived"? On the Smart Biotech Scientist Podcast, Tim Corcora...

How early in process development should you address glycosylation? This episode presents the case for co-optimizing glycan profiles with productivity from initial process characterization. Deferring glycosylation characterization until after titer targets are met introduces risk: quality attribute gaps discovered late in development force process re-optimization, extended timelines, and potential...

When your biosimilar analytical data shows 1.4% high mannose against a 6% reference product specification, you face limited options: process temperature shifts that compromise titer, kifunensine supplementation that requires extensive regulatory justification, or 12-18 months to reclone and revalidate. Media supplementation offers an alternative pathway—tuning glycan profiles through formulation a...

Hard-to-treat cancers like pancreatic ductal adenocarcinoma (PDAC) have long defied conventional therapies. Radiopharmaceuticals, combining targeted therapy with diagnostic power, are creating new opportunities in precision oncology.
