Alexei "Lex" Fridman (/ˈfrdmən/; born 15 August 1983) is an American computer scientist and podcaster. Since 2018, he has hosted the Lex Fridman Podcast, where he interviews notable figures from various fields such as science, technology, sports, and politics.

Fridman rose to prominence in 2019 after Elon Musk praised a study Fridman authored at MIT, which concluded that drivers remained focused while using Tesla's semi-autonomous driving system. The study was not peer-reviewed and was criticized by AI experts. That year Fridman transitioned to an unpaid role at MIT AgeLab, and since 2022 has worked as a research scientist at the MIT Laboratory for Information and Decision Systems (LIDS). As of February 2024, Fridman lives in Texas and is still paid by MIT.
