Research Interests

My research interests are astronomical instrumentation (specializing currently in radio) and cosmology (specifically looking at the evolution of the universe during the Epoch of Reionization [EoR]). I'm currently working on developing the intrumentation for HYPERION, a global EoR experiment, for Aaron Parsons in the Radio Astronomy Lab (RAL). I'm also apart of efforts to test the HERA dishes both in Berkeley and the Green Back, WV, NRAO site.


Projects

HYPERION

The Hydrogen Probe of the Epoch of Reionization (HYPERION) is a specialized low-frequency interferometer to study the Epoch of Reionization through the spatial monopole of the 21cm brightness temperature of neutral hydrogen as a function of redshift (i.e. the ''global signal"). The goal of HYPERION is to detect the monopole reionization signal. A detection of this signal could give key insights into the physics and development of our early universe, including information on the formation of the first stars and galaxies.
