Smart Biotech Scientist | The CMC and Bioprocessing Podcast for Process Development and Manufacturing Leaders

Why does CMC development still expect every drug to be one molecule with one peak, when new therapeutics don't always fit neatly into existing regulatory or chemical categories? Matthew O'Connor, CEO of Scientific Affairs at Cyclarity Therapeutics, is developing a drug that sits between a small molecule and a biologic. On the Smart Biotech Scientist Podcast, Matthew shared how his team e...

Scale-up doesn't fail because the science was wrong. It fails because a cell's environment in a shake flask has little in common with its environment in a bioreactor. Christian Witz has spent years building the tools to close that gap: simulating exactly what a cell experiences as it moves from bench to plant, before a single liter is wasted finding out the hard way. Continuing from Part...

You've perfected your process at the bench. Now comes the part that keeps CMC scientists up at night: will it still work at 2,000L? Right now, most teams find out the hard way, through failed runs, wasted batches, and months of delay to patients waiting on a therapy. Christian Witz believes there's a better way: use computational fluid dynamics to see how your cells will actually behave...

Biotech founders often pour everything into building the “perfect” product only to realize their real customers have walked out the door. Chasing perfection can burn money and stall even the most promising CMC innovations. In this episode, David Brühlmann continues his conversation with biotech entrepreneur and investor John Bonham-Carter. John shares his insights on the realities of building and...

Biotech loves talk of disruptive technology, but few have repeatedly shifted the industry's direction. This episode of the Smart Biotech Scientist Podcast focuses on an idea once dismissed as a fool's game: process intensification through perfusion—now the backbone of leading biomanufacturing platforms. Meet John Bonham-Carter, a serial entrepreneur whose fingerprints are on some of biot...

What if building a world-class biotech company didn’t require owning a single piece of manufacturing equipment or even a lab of your own? Most startups obsess over bricks, mortar, and stainless steel. Not Sandra Núñez. She’s challenging the status quo as CEO of Amela Biosciences by running a “virtual plant” model: zero in-house production, everything outsourced, and agility baked into every decisi...

Batch-to-batch variability isn’t just a minor annoyance in bioprocess development; it’s often a systemic design flaw hiding in plain sight. That’s the challenge Sandra Núñez, CEO of Amela Biosciences, set out to eliminate. Drawing on 15 years across Lonza, Medinova, Baxalta, and Biogen, she’s engineered a new generation of animal-free, recombinant protein matrices that promise researchers experime...

Manufacturability challenges in biotech are becoming more complex as therapies become more potent, formats diversify, and timelines compress across the industry. On this episode, David Brühlmann sits down with Sigma Mostafa, Chief Scientific and Technology Officer at KBI Biopharma. Sigma brings deep expertise in early-stage CMC decision-making and has guided countless programs—from upstart startup...

A breakthrough in drug discovery can be derailed in an instant if manufacturability is left as an afterthought. Too many biotech programs hit bottlenecks at scale-up because key decisions in cell line and process development get kicked down the road. On the Smart Biotech Scientist Podcast, David Brühlmann spoke with Sigma Mostafa, Chief Scientific and Technology Officer at KBI Biopharma. She’s spe...

What does it take to crack the code of protein production and why do some proteins stubbornly refuse to cooperate, despite the best efforts of scientists and engineers? Biotech’s ambitions are often limited not by vision, but by the real-world bottlenecks of host cell lines and the unpredictability of post-translational modifications. Nathan Lewis, GRA Eminent Scholar at the Center for Molecular M...

Dormant omics data are a goldmine for CMC innovation waiting to be unlocked. But legacy structures, poor annotation, and spreadsheet chaos hold most biotech teams back from the real breakthroughs. Nathan Lewis, GRA Eminent Scholar at the Center for Molecular Medicine, Complex Carbohydrate Research Center, and Department of Biochemistry and Molecular Biology at the University of Georgia, has a clea...

“Does DNA barcoding actually work?” It's the first question Kent Rapp hears from prospective customers when he pitches Biolinco's DNA barcoding platform. By his own admission, the technology can sound too good to be true. In Part 2 of this conversation, Kent rejoins the Smart Biotech Scientist Podcast to address that skepticism head-on, unpack how subclone variability and bispecific anti...

What if the bottleneck in cell line development isn’t how many clones you screen, but how you track them? Cloning workflows have long relied on brute force: screen more cells, automate harder, and hope that small-scale performance predicts manufacturability. But too often, the “perfect” clone in a 96-well plate turns into a dud when it reaches the bioreactor. That disconnect costs time, money, and...

Your active ingredient is the nucleic acid. So why does a proteolipid vehicle filing include viral clearance studies, stability data and full characterisation of a membrane protein that is not the drug? Because that protein sits on the particle surface, and a component nobody has filed before is the agency's problem regardless of what you call it. Proteolipid vehicles (PLVs), the platform Jit...

Gene therapy only works if the cargo reaches the right cells intact. Adeno-associated viruses (AAV) and lipid nanoparticles have carried the field this far, but both share a constraint: the particle is taken up into an endosome, and the payload has to escape that compartment before it is degraded. Endosomal escape is where a large share of the dose is lost, and it is why delivery, not the genetic...

For decades, drug development has been saddled with costly manufacturing, stringent biosafety requirements, and the limits of conventional carriers. But a new approach—born from cell-derived nanovesicles—could democratize access to advanced therapies and open entirely new doors for oral, topical, and even global vaccine delivery. This week, David Brühlmann welcomes Christopher Locher, CEO and Co-f...

What if the best way to unlock durable, broad-spectrum immunity is to rethink the very vessels delivering our vaccines? While much of the industry focuses on refining existing delivery systems, Christopher Locher is charting a new course—one inspired by nature’s own couriers. Imagine a future where oral vaccines and modular, on-demand manufacturing aren’t just possibilities, but standard practice....

How do you take a model that works in process development and get it accepted for use in GMP manufacturing? That question stalls most bioprocess modeling projects before they start. Ignasi Bofarull-Manzano, Senior Data Scientist and CMC Consultant at Körber Pharma, pushes back on the premise: the process you run today is already governed by a mathematical model, fitted once at small scale during p...

Most bioprocess teams believe a digital twin demands vast datasets and sophisticated models. Ignasi Bofarull-Manzano argues both assumptions are wrong, and that the data already sitting in your Excel files, historians and ELNs is probably enough to start. Ignasi Bofarull-Manzano, Senior Data Scientist and CMC Consultant at Körber Pharma, breaks down what a digital twin actually is, where modeling...

How do you turn a lab-born regenerative medical device into a solution that surgeons actually want to use and investors want to back? The path from academic innovation to clinical adoption is full of practical hurdles and strategic pivots, where compelling science alone isn’t enough. David Brühlmann welcomes back Eva-Maria Balet, whose journey spans tissue engineering research at EPFL to leading R...

Imagine a wound too large for the body to close on its own. That's the problem Eva-Maria Balet set out to solve, not with living cells, but with a structural bridge that lets the body's own healing mechanisms do the rest. In this episode, David Brühlmann welcomes Eva-Maria Balet, Co-Founder & CEO of Regenosca. Trained at EPFL, Eva-Maria brought her fascination with cellular "fac...

Building a cell therapy company is hard. Building a genetically engineered iPSC therapy for the brain, on a preclinical budget, is one of the hardest translational problems in biotech. Every experiment has to move the program closer to an IND, or it's motion without progress. That's the operating constraint Bilal Fares faces as CEO and co-founder of AzureCell, the University of Geneva sp...

Transplant iPSC-derived neurons into a Parkinson's brain and 97% die before they can restore function. Of the 3% that survive, most face the same pathogenic environment that killed the original neurons. This is the compounded biology and CMC problem defining CNS cell therapy today. Bilal Fares, neuroscience entrepreneur and co-founder of AzureCell, is translating a University of Geneva discov...

How much of your research lives and dies on the bench? Not because the idea isn’t sound, but because building reproducible, scalable biomaterials remains an unsolved puzzle. Jan Hunik and Matt Baker from MosaMatrix discuss the practical challenges and lessons learned from spinning out a biomaterials company from academia. They explore the importance of quality standards in biotech startups, buildi...

What if the real obstacle in 3D cell culture and tissue engineering isn't the cells, but the very ground they grow on? For years, cell culture has relied on flat plastic and passive scaffolds. But biology doesn't happen on a petri dish—cells live in three dimensions, surrounded by a dynamic environment that talks back, adapts, and shapes development in ways static gels simply cannot. Tha...
