About Danielle Venton

Aside from being useless behind a microscope, I'm in science writing for the variety. Like many a writer before me, I love language, learning, and talking about science. I love new experiences that deepen my understanding of the world and its people. Science writing gives both author and reader access to every field touched upon by research—which is to say, every field there is. I've worked in science communication from many places: the redwoods of Northern California, the ponds of Cape Cod's National Seashore, and the caverns of the Large Hadron Collider, the largest particle accelerator, at CERN in Geneva. Every new place, every new project, teaches me something and broadens my perspective. The world will always have something new to teach us, and science writing allows me to remain its student.
