About

I’m a writer, a songwriter and a scientist. I earned a Ph.D. in astronomy in 2001 from Caltech and I’ve worked as an astrophysicist for Harvard, Princeton and NASA. Planets, young stars, Kuiper Belt objects, brown dwarfs, supernovae, disks, dust…my specialties.

One cloudy night at the telescope, I grabbed a guitar and started writing songs. Some of my songs have been covered by aspiring pop and country artists and appeared on VH1, MTV, BET, and PBS.

Younger scientists started asking me to mentor them. But I didn’t know how. So I collected all the advice I could gather into a book called: Marketing for Scientists: How to Shine In Tough Times (Island Press 2011). It’s a guide to help researchers share the joy of discovery while building their careers.

Now I have two fascinating children, so I write books for them–and any other children that might wander by. My first experiment with kidlit is the new Cosmic Collisions series (MIT Kids Press). These books challenge you to hypothesize what will happen when two astronomical objects slam together. Read on, watch the collision unfold, and see if you guessed right!

Cosmic Collisions

Supergiant vs. Neuton Star is the newest book in the Cosmic Collisions series. it’s just right for 7-9 year olds (second, third and fourth graders). It comes out in, 2025, published by MIT Kids Press, and illustrated by Matt Schu. You can pre-order it now!

Asteroid vs. Comet was released last year. Publishers Weekly said “It’s an exuberant book that packs an out-of-this-world punch.” A comet is speeding in from the outer solar system, and an asteroid is right in its path. Which one will survive this interplanetary smackdown? Stay tuned for more titles to come!

Speaking/Contact

I love to talk to children about writing, and I am available for school visits. I also give Marketing for Scientists workshops to scientists, graduate students and researchers of all kinds. Send me an email if you’re interested.
