This week on The Genetics Podcast, Patrick is joined by Dr. Jagesh Shah, Chief Scientific Officer at Mirai Bio. They discuss why delivery is a central bottleneck holding back nucleic acid medicines, how Mirai's lipid nanoparticle (LNP) platform is built to reach tissues like adipocytes and T cells, and the machine learning feedback loop the company uses to engineer LNP formulations.
