Welcome to my website!

I, Xu He (H. Xu), was a schoolboy in Tianjin's YaoHua School, a
graduate in Physics from NanKai University, and a professional
engineer with the China Academy of Building research.
I pursued postgraduate studies at the Bartlett School of
University College London, UK, with a project entitled
"Assessing lighting performance in terms of communication theory".
During that period, I turned to the field of color rendering, and
developed the idea of Color Rendering Capacity, which gives an answer
to one of the many questions arising from my childhood curiosity.
