An excellent complement to competitions – Lumiere Research Scholar Program


Competitions go hand-in-hand with great research skills and projects. Great research skills often groom you to problem-solve during competitions and, they both look really good on college applications for entirely different reasons!


If you are passionate about research, you could also consider applying to the Lumiere Research Scholar Program, a selective online high school program for students that I founded with researchers at Harvard and Oxford. Last year, we had over 2100 students apply for 500 spots in the program! You can find the application form here.


Stephen is one of the founders of Lumiere and a Harvard College graduate. He founded Lumiere as a PhD student at Harvard Business School. Lumiere is a selective research program where students work 1-1 with a research mentor to develop an independent research paper.
