Mark Rober
Engineer & YouTuber
Mark Rober is an American engineer and YouTube creator known for science and engineering videos that combine elaborate builds, accessible explanation, and playful experiments. A former NASA engineer, he has become one of the most popular educational creators on YouTube, with a channel followed by tens of millions of subscribers.
Early life
Rober was born in 1980 and grew up in California. He studied mechanical engineering, earning a bachelor's degree from Brigham Young University and a master's degree from the University of Southern California. His interest in building and problem-solving, encouraged from an early age, shaped both his engineering career and his later work as a creator.
Career
Rober worked for nearly a decade at NASA's Jet Propulsion Laboratory, where he contributed to the Curiosity rover that landed on Mars, among other projects. He later worked at Apple, reportedly on hardware and product development. His online career began as a side project: an early viral video featuring a Halloween costume that used tablet screens to create an illusion of a hole through the body drew wide attention and encouraged him to continue making videos.
He gradually shifted his focus to full-time content creation, building a YouTube channel centered on large-scale engineering demonstrations and experiments. His videos often pair a clear scientific premise with ambitious physical builds, covering topics such as record-setting devices, animal behavior tests, and consumer-protection stunts. One recurring series featured a "glitter bomb" package designed to deter and document parcel thieves, which became among his most widely viewed work.
Recent work
Rober has expanded beyond standalone videos into education-focused ventures. He founded CrunchLabs, a company that produces build-it-yourself engineering kits and educational content aimed at encouraging young people to pursue science and engineering. He has also been involved in efforts to make engineering education more engaging and hands-on.
He has played a prominent role in large online fundraising campaigns, helping organize and promote #TeamTrees, which raised funds to plant millions of trees, and the follow-up #TeamSeas, focused on removing waste from oceans and waterways; both initiatives brought together many creators around environmental goals. His videos frequently emphasize curiosity, iterative testing, and the idea that engineering can be approachable and fun.
Rober is widely credited with popularizing engineering content for a broad audience and inspiring interest in science, technology, engineering, and mathematics among younger viewers. He continues to produce videos that blend entertainment with instruction, maintaining a reputation as one of the leading figures in educational online media.
