Hello! I’m Jack, a weather science data reporter with the San Francisco Chronicle.

I’m part of the California Weather Wonks, a small but mighty team dedicated to explaining the how and why behind weather in the S.F. Bay Area and California.

My path to science journalism has taken a few twists and turns. I earned a Ph.D. in molecular biology at Princeton Unversity and worked as a data engineer before completing the science communication program at UC Santa Cruz. Since then, I’ve written about a variety of science topics, from dinosaur eggs to heat waves to cancer prevention, through internships and as a freelancer.

Now, I’m excited to have the opportunity to dive into datasets and talk with scientfic experts, to share the fascinating story of Bay Area weather!
