But Shuji’s journey to this point is one of resilience and perseverance. In his pursuit to discover the first commercial white LED, he had to overcome many obstacles along the way.

He set out to get his PhD degree and found one of the most sought-after inventions along the way.
Professor Shuji Nakamura speaks to Natasha Fernandes about finding the light and how it might not be what you would expect.
