At YLabs we bring together the science of adolescent development, behavioral economics and human-centered design to build and test programs that can enhance the unique potential of adolescents. We founded YLabs in 2015 at the Harvard T.H. Chan School of Public Health. We started as residents at the Harvard Innovation Lab and have grown into a team of researchers from the US, UK, Rwanda, Senegal, India, and Canada. If you want to join us as we build YLabs please look at our current opportunities and contact us. We would love to hear from you.
