We are made of star dust. Stars live by fusing elements in their centers, and when they die those elements are blown out into space and incorporated into new stars, into new planets, and into life like you and me.

How stars live and die is determined by their internal physical properties - like density, temperature, chemical composition. These internal properties are not well understood.

Telescopes can only see the surface of stars. To learn about the insides of stars we need asteroseismology — the study of waves generated inside stars and which can be seen at the surface. 

My current work uses open-source computational models to investigate how the internal structure of stars is related to the waves they can harbor which could be seen on their surface. I work in collaboration with Dr. Richard Townsend and Dr. Ellen Zweibel.

An emerging branch of multi-messenger astronomy studies coincident gravitational and electromagnetic radiation. Gravitational waves, as predicted by General Relativity and detected by aLIGO, carry unprecedented and otherwise unobtainable information on astronomical phenomena ranging from black holes to the big bang. 

Inspiraling compact objects (black holes, white dwarfs, and neutron stars) are promising sources of multi-messenger signals. My work at UC Santa Cruz focused on building a computational model to investigate whether white dwarfs spiraling into black holes could generate both detectable gravitaitonal waves and electromagnetic counterparts.

I worked in collaboration with Dr. Enrico Ramirez-Ruiz and with graduate student Morgan Macleod of Theoretical Astrophysics Santa Cruz.

I was a member of the Supercomputing Lab for Undergraduates.
