He began modelling when he was discovered by Giorgi Armani at age 6, and since then has been featured by brands and magazines including GQ, Equinox Fitness, Emporio Armani EA7, Attitude, Vouge Hommes, Abercrombie & Fitch, and has been shot by photographers including Bruce Weber, Giampalo Sgura, and Ollie Ali.

Pietro’s interests in fitness led to his innovative YouTube strength training channel being viewed millions of times, and the launch of his own fitness-oriented fashion line Pietra Design.

A Facebook post by one his University of London engineering students went viral in 2015 and led to his being dubbed “the world’s sexiest math teacher”, to which Pietro replies, “I model the fluid thermodynamics of wet steam flow”.

Rational mind is the continuation of that philosophy: using the global platform he has been gifted to help millions of curious people discover more about how their world works, and how to think about it.

For RATIONAL MIND, Pietro chose to collaborate with ATOMIC ENTERTAINMENT, the Emmy-nominated creators & executive producers of BRAIN GAMES, BRAINCHILD and the WHO SMARTED? podcast. Pietro And Atomic's founders, Jerry Kolber and Adam Davis, all share the belief that critical thinking, science and enabling discovery are the keys to making the world a better place.
