Smart Biotech Scientist | The CMC and Bioprocessing Podcast for Process Development and Manufacturing Leaders
The go-to CMC and biomanufacturing podcast for bioprocess development scientists and CMC leaders scaling biologics into regulatory-ready therapies with less trial and error.
Practical, execution-focused, and strategic guidance on CMC development, tech transfer, scale-up, GMP readiness, CDMO partnerships, and manufacturing economics for biologics, cell and gene therapies, cultivated meat, and biomaterials.
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, hybrid modeling, manufacturing economics, continuous manufacturing, digitization, and Industry 4.0 in biopharma.
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.

246: Why Your Shake Flask Culture Doesn't Scale: OTR, Shaking Diameter, and How to Fix It with Tibor Anderlei - Part 2
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
Shear sensitivity is the silent challenge behind many advanced biomanufacturing modalities. Orbital-shaken bioreactors—often underestimated—may be a key enabler your CMC development is missing.
Tibor Anderlei, CSO at Kühner Shaker, joined David Brühlmann on the Smart Biotech Scientist Podcast to unpack the hidden physics behind bioprocess reproducibility and next-generation shaking technology. He has seen firsthand how overlooking fundamental parameters can derail scale-up and delay development timelines. In his role, Tibor is responsible for the customer interface—spanning sales, service, support, GMP topics, troubleshooting, marketing, and applied technology—with a focus on orbital shaking technology and small-scale cultivation support.
Topics discussed:
- The importance of measuring oxygen transfer rate (OTR) and carbon dioxide transfer rate (CTR) for reproducible bioprocesses—why DO is not sufficient (02:55)
- Real-time process analytical technology (PAT) for small-scale bioreactors, including microtiter plates and shake flasks (06:47)
- Pre-culture reproducibility: transferring at the right OTR and its impact on main cultures (07:56)
- Price sensitivity and scale-up challenges in cultivated meat—implications for media and equipment selection (10:36)
- Expansion of shaking technology to fields such as mixing, storage, and thawing, including applications in liquid crystal production (12:10)
- Leadership lessons from competing with bigger players: how smaller companies stay innovative, agile, and close to their customers (14:20)
- The significance of strong business partner relationships and trusting gut feeling in decision-making (16:32)
- Key advice for smart biotech scientists: careful definition of screening conditions and the use of online measurement tools at small scale (18:09)
- Accessible resources for mastering shaken bioreactor techniques, including webinars and direct contact with Tibor Anderlei (19:38)
Smart insight:
Treat small-scale shaken systems as real bioreactors and define screening conditions carefully from the start. Using online measurement tools even at early stages provides critical visibility and helps ensure that results are reproducible and scalable.
Building a robust scale-up strategy requires looking at the process from multiple angles—regulatory, digital, and operational. Listen to those previous episodes:
