Smart Biotech Scientist | The CMC and Biomanufacturing Podcast for Process Development and Manufacturing Leaders
The go-to CMC and biomanufacturing podcast for process development scientists and CMC leaders scaling biologics into regulatory-ready therapies with less trial and error.
Practical, execution-focused guidance on CMC development, tech transfer, scale-up, GMP readiness, CDMO partnerships, and manufacturing economics.
Hosted by Dr. David Brühlmann, CMC strategist, former Bioprocess Innovation Manager at Merck, PhD in glycoengineering, and close to 20 years of biomanufacturing experience. Smart Biotech Scientist delivers actionable insights for the people doing the hard work of turning promising molecules into scalable, regulatory-ready therapies.
This podcast is for you if:
- You are a process development scientist or CMC lead managing a technology transfer, scale-up, or CDMO partnership
- You are a biologics developer working on upstream or downstream process development, cell culture optimization, or GMP manufacturing readiness
- You are a biotech founder preparing for an IND filing or Series A fundraise, and need a CMC strategy that holds up under investor and regulatory scrutiny
- You are building or advising an early-stage biopharma team and need to make smart manufacturing decisions with limited resources
What you will learn:
CMC strategy and regulatory planning, bioprocess scale-up from lab to clinical and commercial manufacturing, cell culture process development and media optimization, technology transfer best practices, CDMO selection and partnership management, cost of goods modeling and manufacturing economics, continuous manufacturing and Industry 4.0 in biopharma, biologics modalities including mAbs, ADCs, and cell and gene therapies.
Top 10 life sciences podcast with 200+ episodes and guests from Merck, FUJIFILM Irvine Scientific, Cytiva, KBI Biopharma, Eppendorf, and biotech innovators worldwide.
New episodes released weekly. Subscribe and join 400+ biotech leaders already using these insights to accelerate development, reduce manufacturing costs, and de-risk scale-up.

191: Process Intensification Secrets: A Process Engineer's Decision Framework with Andreas Castan - Part 1
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
What if process intensification could transform your bioprocessing economics without the complexity most engineers fear? Getting 3x productivity gains and 30-150% titer increases once seemed reserved for Big Pharma's endless R&D budgets, but a strategic approach to technology selection is making these results achievable for companies of any size.
In this episode, David Brühlmann speaks with Andreas Castan, a bioprocess veteran with over 25 years of industry experience who provides leadership and support to Cytiva's bioprocess business. Andreas brings deep expertise from directing upstream development at Swedish Orphan Biovitrum and extensive work in expression systems, process development, scale-up, and cGMP manufacturing across multiple therapeutic modalities.
Why tune in? Here's your process engineer's roadmap:
- Process Intensification Economics Decoded: Andreas reveals the cost-benefit reality behind continuous vs fed-batch manufacturing, including real process economic modeling data showing why the differences aren't as dramatic as you'd expect and what factors actually drive your business case.
- Low-Hanging Fruit That Delivers: Skip the overhyped AI solutions. Andreas shares the strategic fundamentals that work: high-producing cell line development, N-1 perfusion for rapid productivity gains, and smart bioreactor turndown strategies that eliminate process steps without adding complexity.
- Decision Framework for Technology Selection: Learn when continuous processing makes economic sense (and when it doesn't), how media costs impact your COGS analysis, and why understanding your bottlenecks, not following industry trends, should drive your intensification strategy.
- Industry Insider Strategies: Get the inside track on what AstraZeneca, Sanofi, Merck, Lonza, and Takeda are actually implementing, plus Andreas's perspective on why human expertise and mechanistic insights still outweigh AI in real-world process decisions.
Ready to make smarter technology investments and achieve measurable productivity gains? This isn't theory. It's a practical guide to process intensification economics that you can apply whether you're preparing for Phase I or scaling for commercial manufacturing.
