Meet the Team
Studia.app was built from 2019 to 2021 by a team of three PhD students from the University of Notre Dame and the University of Toronto (more about us below). As teachers, we realized how difficult it was to find clear, accurate, and easily accessible resources for working through certain types of physics problems. We wanted to help! Although we eventually found more stable jobs (running a startup while finishing a PhD is challenging!) we still believe that Studia is unique and can significantly assist many students struggling in their physics classes. Since 2023, Sebastián has undertaken the work of keeping the website running and ensuring it remains freely accessible to the general public.
