PhD Graduate Student

Eliot Raschetti

Eliot joined the team in Spring 2026. He will study tidal disruption events (TDEs) detected at radio wavelengths, indicative of a newly formed jet or outflow. 

Joshua Goodeve_edited.jpg

PhD Graduate Student

Joshua Goodeve

Joshua joined the team in 2024. He is co-supervised by Adrian Liu. He will be researching how slow radio transients could be detected by CHORD and whether they could be caused by active galactic nuclei, tidal disruptions and/or GRBs.
