Daniel Wagner joined Snap in 2019 and, as Senior Director of Software Engineering, leads software development for Snap's SPECS program. Before joining Snap, Daniel was Chief Scientist and later CTO at DAQRI, where he developed novel industrial Augmented Reality software and hardware. Based in Vienna, Austria, he brings 25 years of industrial and academic experience in Augmented Reality and is widely recognized as a pioneer of AR on mobile phones. During his PhD studies he built the first 6DOF natural feature tracker to run in real time on a smartphone, and his seminal thesis "Handheld Augmented Reality" laid the foundation for the advent of mobile AR. After his university career, which led to the development of the Vuforia AR library, Daniel joined Qualcomm's research team and continued his work on mobile Augmented Reality. Some of Daniel's algorithms are implemented in hardware in every mid- and high-range Qualcomm chip today.
