Sansan Harashima (@mossgirlny) is a writer and photographer based in New York.

She spent years in the fashion industry as a trend forecasting executive, developing a sharp eye for color, texture, and design.

When her son Lucas was diagnosed with DIPG, a rare childhood cancer, she found herself drawn to the moss in her own backyard and began photographing and writing about it, building an online community around the simple beauty she'd found. She is also cofounder of the Love4Lucas Foundation, which supports DIPG research.
