Meet Juli Berwald—a marine biologist turned science writer and the author of an invertebrate page-turner—she’s the founder of a coral-reef nonprofit in Honduras, aaaaand she’s producing her first doc. Throughout our waterfront walk at Ladybird Lake Juli opens up about her adventures in science writing—how getting fired off a book project (& replaced by Elizabeth Kolbert) inspired Juli to create her own destiny and finally write her own book.

What follows is a masterclass in turning science into memoir called SPINELESS—a jellyfish book secretly structured like a jellyfish lifecycle, complete with a fever dream that sent her to Japan to find the world’s biggest jellyfish (spoiler: it died right in front of her). We dig into “hiding behind the facts,” the boldness it takes to put yourself on the page, and the best creative-accountability advice we’ve heard yet: combine a tight writing group with Elizabeth Gilbert’s “take your project on a date,” add in some John August-style sprints while following a roommate’s admonition to “write the worst book you can—”and you’re on your way.

Theres’s a whole lot of science, a bunch of laughs, and some doc-stuff in this one too. THE REBEL REEF: SEEDS OF HOPE is Juli’s hopeful short doc about a reef to remember and divemaster Christian Carias, whose own healing becomes the heart of the film. Plus composer Chad Cannon (AMERICAN FACTORY, JOIN OR DIE), a $100K biobank dream, and perhaps an answer to the question of “how do you get to Symphony Space?”

Also: An entire taxonomy of recumbent coots; shoutout to a Charles and Ray Eames numerically inspired mid-century film; and the official-yet-disputed name of a celebrated Austin footbridge. And yes—Juli already has another book on the way…
