My name is Wolf Paulus, I’m a software engineer, innovator and educator based in Sedona, Arizona (consequently a hiker and photographer). This is my journal, where I share thoughts and ideas on technology.
I’m an Assistant Professor of Computer Science at Embry-Riddle. Occasionally, I speak at conferences on topics ranging from Embedded/Mobile Technology to Emotional Prosody and Voice and Conversational User Interfaces.
