Dr. Morgan McSweeney (Dr. Noc)

Dr. Morgan McSweeney, known on social media as Dr. Noc, is an American immunologist and pharmaceutical scientist based in southwest Florida who holds a PhD in pharmaceutical sciences and innovation. His laboratory research focuses on developing monoclonal antibody-based therapeutics for respiratory infectious diseases, including influenza, RSV, and COVID-19. He began posting short-form science content on TikTok during the pandemic and has since built a following of more than four million across platforms, with his content reaching approximately 30 to 50 million viewers per month.

Dr. Noc's approach to science communication is explicitly styled as "edutainment," blending genuine scientific depth with entertainment formats that hold attention on platforms dominated by short-video content. His videos debunk common health misinformation — from COVID vaccine myths to misleading claims about Tylenol use in pregnancy and autism risk — while explaining the underlying science accessibly enough for non-specialist audiences. He has been featured in the New York Times, Time magazine, the World Economic Forum, and on NBC and Fox, and was named among TikTok's top doctor influencers.

In 2025, Stat News profiled McSweeney at length, with him reflecting on the challenges and responsibilities of science communication at scale. He has spoken publicly about the importance of relatability in public health messaging, arguing that being engaging and personable is not a compromise of scientific integrity but a prerequisite for reaching the audiences most in need of accurate information. His combination of genuine research credentials and platform fluency makes him one of the more significant figures in the current generation of social media science communicators.
