Utkarsh Mittal and the three minute thesis.
(Dr!)Utkarsh Mital is a VERY recent PhD graduate. In fact, Kevin, Griff and guest co-host Erin Darling had to move the recording until after his defense. Mittal isn't just an engineer, he's an actor, has a role in "PHD Movie 2", and won the People's Choice Award for the Three Minute Thesis competition.
