“You've gotta get in the house without the alarms going off.”

Örn Almarsson compares therapeutic mRNA delivery to a covert package drop: the payload has to reach the right room, release its contents, and leave without triggering the immune system.

He looks back at Johnson & Johnson, Alkermes, and the relationships that shaped his next move. A referral from Bob Langer led him to Moderna, where he joined a small team working through one of biotech's hardest engineering problems.

The conversation covers layoffs, company transformation, patent cliffs, biotech's feast-and-famine cycles, modified mRNA, and the effort required to scale production from tiny academic batches to grams and kilograms.
