This week, our “Masters in Business” radio podcast features Brad Katsuyama of IEX. Katsuyama may be best known for his role as the lead character in Michael Lewis’s book, "Flash Boys: A Wall Street Revolt."

In our podcast, Katsuyama describes how it became clear that something had changed in the market structure, but no one really knew what it was. He explains how he and his team eventually unraveled how algorithm-driven high frequency trading worked. 

We also chat about his appearance on "60 Minutes," and his debate on CNBC with William O’Brien, former president of the BATS Global Markets stock exchange.

Listen to the podcast here, on BloombergApple iTunes or SoundCloud. All of our prior podcasts are now available on iTunes.

Next week, we speak with Mebane Faber, chief investment officer of Cambria Investment Management
