Dr. Harini Bhat is a clinical pharmacist turned science storyteller who built a following of 2.5 million by making complex science feel like something you can't stop watching. Her popular YouTube series Today I Learned Science boasts 105 million views and 650K+ subscribers. She also hosts PBS’ In the Margins, an NAACP-nominated series bridging digital-first science with premium educational TV.

She’s now bringing that same rigor and wonder to Hidden History, a new Rewind original series that examines history's most baffling unsolved events not as myth or curiosity, but as incomplete case files waiting to be reopened.
