David Hanson Jr. is an American roboticist who is the founder and Chief Executive Officer (CEO) of Hanson Robotics, a Hong Kong-based robotics company founded in 2013. 

The designer and researcher creates human-looking robots who have realistic facial expressions. 

He is mainly known for Hanson Robotics, the company that created Sophia and other robots designed to mimic human behavior. Sophia has received widespread media attention, and was the first robot to be granted citizenship.

Hanson was born on December 20, 1969 in Dallas, Texas, United States. He studied at Highland Park High School for his senior year to focus on math and science. As a teenager, Hanson’s hobbies included drawing and reading science fiction works by writers like Isaac Asimov and Philip K. Dick—the latter of whom he would later replicate in android form. 

Hanson has a Bachelor of Fine Arts from the Rhode Island School of Design in film/animation/video, and a Ph.D. from the University of Texas at Dallas in interactive arts and engineering. In 1995 as part of an independent-study project on out-of-body experiences, he built a humanoid head in his own likeness, operated by a remote operator.

After he graduated from university, Hanson worked as an artist, and went on to work for Disney where he was a sculptor and material researcher in the Disney Imagineering Lab. He has worked as a designer, sculptor, and robotics developer for Universal Studios and MTV. In 2004, Hanson built the humanoid robot Hertz, a female presenting animated robot head that took about nine months to build. 

Hanson is the founder and CEO of Hong Kong-based Hanson Robotics, which was founded in 2013.

Hanson’s career has focused on creating humanlike robots. Hanson's most well-known creation is Sophia, the world's first ever robot citizen.

Sophia is a social humanoid robot developed by Hong Kong-based company Hanson Robotics. Sophia was first turned on on February 14, 2016, and made her first public appearance at South by Southwest Festival (SXSW) in mid-March 2016 in Austin, Texas, United States. 

Sophia has been covered by media around the globe and has participated in many high-profile interviews. In October 2017, Sophia "became" a Saudi Arabian citizen, the first robot to receive citizenship of any country. In November 2017, Sophia was named the United Nations Development Programme's first ever Innovation Champion, and is the first non-human to be given any United Nation title.
