About me
Hello! I’m an astrophysicist who builds models of particle acceleration. I use these models to connect theory with observations of extreme phenomena such as supernova remnants and winds launched by active galactic nuclei. I’m currently a postdoc at the Institute for Advanced Study in Princeton and at Columbia University in New York City. Before that, I earned my PhD in Astronomy and Astrophysics from the University of Chicago.
My research interests include:
Cosmic rays
Acceleration and propagation
Astrophysical shocks
Supernova remnants, novae, black hole winds, and more
Multi-messenger emission
Photons from radio to gamma-rays, charged particles, and neutrinos
astroparticle instrumentation
Balloon-borne and space-based detectors
CRAFT
At the core of my PhD work was my development of CRAFT (Cosmic Ray Analytical Fast Tool), a model of particle acceleration that runs in seconds on a laptop, yet self-consistently incorporates results from state-of-the-art kinetic simulations. This movie shows the CRAFT-predicted multi-wavelength emission from a supernova remnant expanding into a dense stellar wind followed by a uniform interstellar medium.
