Hosted by EIC Mikael Angelo Francisco, Ask Theory shines the spotlight on Pinoy scientific brilliance, in a fun and entertaining “kwentuhan” format. Each episode of Ask Theory  features a Pinoy scientist from one of the various scientific disciplines. In a very casual conversation, guests explain what they do in simple terms, as well as share their fascinating stories: how they got into science, the challenges they face, what motivates them to pursue their fields, what future scientists from the Philippines can look forward to, and so much more.
