Astronomer at the University of Maryland/NASA Goddard Space Flight Center

I am currently a postdoctoral researcher working at the NASA Goddard Space Flight Center, employed through the University of Maryland, College Park through CRESST II.

My research focuses on studying small physical scales in distant galaxies, down to the level of individual stars. I examine galaxies that have been magnified by gravitational lensing, which enables us to see smaller features than would be visible in unlensed galaxies. In some cases, this includes magnifying individual stars by such large amounts that the can be distinguished from their host galaxies at great distances.

I primarily use the Hubble and Webb Space Telescopes for my research.
