Liz Dreyer is an Early Career Professional Member of SPIE and chair of the SPIE Future Leaders Committee. Liz is also the next community member to answer our 'Why Light?' series. The series is leading up to the first International Day of Light, and asks SPIE Members to explain why they feel light is so important. The inaugural International Day of Light – IDL – will take place 16 May 2018. IDL is a global initiative that provides an annual focal point for the continued appreciation of light. This day recognizes light and the vital role it plays in science, culture and art, education, and sustainable development. On 16 May, join SPIE and communities worldwide by participating in activities that illustrate how the science and art of light improves all our lives.
