Lawrence Maxwell Krauss is a Canadian-American theoretical physicist and cosmologist, born on May 27, 1954, in New York City, U.S. He taught at several prestigious institutions, including Arizona State University (ASU), Yale University, and Case Western Reserve University. He founded ASU's Origins Project in 2008 to explore fundamental questions about the universe and served as its director.

Krauss is a staunch advocate for the public understanding of science, evidence-based public policy, scientific skepticism, and science education. As an anti-theist, he aims to diminish the influence of superstition and religious dogma in popular culture.

He has written several bestselling books such as The Physics of Star Trek (1995) and A Universe from Nothing (2012). Krauss also chaired the Bulletin of the Atomic Scientists Board of Sponsors.

Despite his achievements, Krauss faced allegations of sexual misconduct. An investigation by ASU confirmed policy violations, leading to the non-renewal of his directorship of the Origins Project in July 2018. He retired as a professor at ASU in May 2019. Currently, he serves as the president of The Origins Project Foundation, hosts The Origins Podcast with Lawrence Krauss, and writes a blog titled Critical Mass.
