He has founded several startups including Origin Wireless, which pioneered AI for wireless sensing and indoor tracking. Under Liu's leadership as chief executive, the company invented the world's first centimeter-accuracy indoor positioning and tracking system using the principle of “time reversal." The invention is now available in more than 150 countries.
Liu has held many volunteer positions. He was the 2019 vice president of IEEE Technical Activities. As 2012–2013 president of the IEEE Signal Processing Society, he established a new membership board to offer more benefits to society members—which resulted in increased membership. In 2005 he cofounded the IEEE Signal Processing chapter in Washington, D.C. From 2003 to 2005, he was editor-in-chief of IEEE Signal Processing magazine.
He was also the 2016–2017 Division IX director.
Liu was elevated to IEEE Fellow in 2003 “for contributions to algorithms, architectures, and implementations for signal processing."
He was inducted as a Fellow of the American Association for the Advancement of Science in 2008 and of the U.S. National Academy of Inventors last year.
He has received numerous IEEE honors and recognitions including the 2009 IEEE Signal Processing Society Technical Achievement Award, the 2014 IEEE Signal Processing Society Award, and the 2016 IEEE Leon K. Kirchmayer Graduate Teaching Award.
