Anthony C. Perry

Founder & Engineer

Anthony is a researcher and engineer with graduate training in kinesiology and computer science. He served in the U.S. Air Force as a C-17 loadmaster, studied motor learning and neurophysiology at San Diego State and California Baptist University, and holds a second master’s in AI and machine learning. The through-line: the science of how people learn is well-established, but most study tools ignore it.

Meridian Labs applies that science. The methodology draws on 33 peer-reviewed studies in confidence calibration, spaced repetition, misconception detection, and stress inoculation training. Anthony designs every algorithm, generates every question framework, and ships production applications across four brands and 28 apps serving IT, healthcare, beauty, and professional certification exams.
