Łukasz Sebastian Gottwald, known professionally as Dr. Luke, Tyson Trax, and Made in China, is an American songwriter and record producer. His professional music career began in the late-night television sketch comedy show Saturday Night Live as its house band's lead guitarist in 1996 and producing remixes for artists such as Bon Jovi and Gravediggaz. He came into music prominence in 2004 for producing Kelly Clarkson's single "Since U Been Gone" with Swedish record producer Max Martin.
Gottwald continued to co-write and produce commercially successful records such as "Who Knew" (2006) for Pink, "Girlfriend" (2007) for Avril Lavigne, and "I Kissed a Girl" (2008) for Katy Perry, before leaving Saturday Night Live and reuniting with Clarkson for "My Life Would Suck Without You" (2009). As the founder of both Kemosabe Records and Amigo Records, Gottwald has signed artists such as Kesha, Doja Cat, Becky G, Juicy J, R. City, and Lil Bibby to the former, as well as Kim Petras and Joy Oladokun to the latter.
In 2014 Gottwald was involved in a legal dispute with Kesha where she alleged abuse and employment discrimination, whilst he claimed a breach of contract and defamation. The case Kesha v. Dr. Luke was settled out of court in June 2023.
Gottwald owns two publishing companies, Kasz Money Publishing, for his own songs, and Prescription Songs, which employs other songwriters. As of January 2011, he has garnered 21 Top 40 Billboard Hot 100 singles, becoming the producer with the third most such hits since the charts were created. His work has been recognized with various music industry awards. Billboard named him one of the top performing producers of the 2000s. The American Society of Composers, Authors and Publishers awarded him Producer and Songwriter of the Year honors from 2009 to 2011. At the 53rd Annual Grammy Awards, he was nominated for a Grammy Award for Producer of the Year, Non-Classical, and Perry's Teenage Dream was nominated for Album of the Year.
