Vranch graduated from Cambridge University with a PhD in physics. While a first-year doctoral student, he joined the Footlights in 1981 and was a contemporary of Stephen Fry, Hugh Laurie, Morwenna Banks, Tony Slattery and Neil Mullarkey.

He performs as a stand-up comedian, and with Pippa the Ripper he is half of the hula-hoop/science double act Dr Hula.
