Picasso, Pick-Up Lines, & Personalized Medicine: mRNA's Path Forward6/27/2025
Overall, my presentation on what the mRNA industry can learn from the artist Picasso singled out a few specific areas from which I felt our industry could garner greater inspiration and operational prowess. But given how “collaborative” many of these sources of inspiration are, I’ve introduced each of my takeaways with a surprisingly relevant (albeit bad) art-themed pick-up line. After all, if there’s one sector that knows it takes more than one to “tango,” it’s the mRNA industry.

Britney Spears' Take On Building Platform Analytics for mRNA Therapeutics4/2/2025
As many of the presentations throughout the two-day USP quality forum revealed, we’re doing what we must to understand the benefits and the limitations of our methods. Yes, this is painstaking and expensive work. But understanding our methods is also one of the critical steps toward a future in which we can rely upon platform analytical procedures and — channeling our inner Britney Spears — say “[Ooo], I did it again!” to the regulatory agencies for each of the subsequent molecules in our pipelines.
