Variable Stars

Detection and characterisation of interesting exoplanet systems.


As seen on TV. (And heard on podcasts!)

NASA's Unexplained Files

I appeared in eight episodes across two seasons of the Discovery Science channel program 'NASA's Unexplained Files', talking about interesting planets discoveries. Click above for a short clip about Kepler-186f.

The Science Behind "The Expanse"

I joined the cast, writers and production crew of the Syfy show "The Expanse" in a live, recorded panel event at Caltech discussing some of the fantastic science behind the show.

"Under The Same Stars"

I sat down recently with writer and director Ali Alvarez, to be interviewed for her new upcoming documentary entitled "Under The Same Stars", about female astrophysicists in the US. The film is planned for release in 2018.

Surely You're Joking!

I joined Dr. Kevin Hickerson and his co-hosts Owen Benjamin and Griff Pippin for this episode of 'Surely You're Joking', a science and comedy podcast. We discuss the release of 1284 new planets from the Kepler mission


Dr. Carrie Nugent hosts this podcast, which gives an insider view into space exploration. On this episode, we discuss how to search for exoplanets, and how good a lemon, lime and bitters is.

Spacepod again!

I joined Dr. Carrie Nugent a second time on Spacepod to talk about the thrilling tale of discovery and characterisation of the triple-planet system, HD 3167. We also drink a preternaturally blue drink.

Here is some coverage of our announcement at AAS 231 of the discovery of K2-138.

The astronomers behind System Sounds (particularly postdoc Matt Russo) have created a beautiful visual and aural experience of our new exoplanet system. It is SO COOL. Every time one of the planets passes between us and the star, it makes a note. The tone of the note (how high or low it is) is determined by the planet's orbital period. It sounds so pretty because of the cool chain of resonances that these planets are in! Have a listen!
