I’ve written about almost every field of science at one time or another, but I write most often about physics, Earth science, ecology and environment (the “plants and particles” beat as I sometimes call it). Some of my favorite stories come from the interface between physics and fields like ecology and cancer research. Whatever the topic, my goal is always to communicate what scientists do, how they think and why it matters.
Below is a mostly complete list of my published writing to date.
