Lauren Rhodes.jpg

Postdoctoral Fellow

Lauren Rhodes

 Lauren joined in 2024. She uses radio telescopes to study relativistic jets launched by black holes of all masses.

Sophia Waddell.jpg

Postdoctoral Fellow

Sophia Waddell 

Sophia joined the team in 2024. Sophia is an expert in X-ray observations of growing supermassive black holes.

Hannah Dykaar

Postdoctoral Fellow

Hannah Dykaar

Hannah joined in 2025. She studies tidal disruption events (black holes eating stars!) and other transient radio phenomena.

MSc Graduate Student

Zach Sumners

Zach joined the team in 2024. He will be using machine learning and mutli-wavelength observations from Chandra and JWST to investigate Sgr A*. He is co-supervised by Dr. Yashar Hezaveh at UdeM/Ciela.

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.

MSc Graduate Student

Rebecca Hamel

Rebecca joined the team in 2024. She uses Bayesian Inference via the SPARK tool to understand the spectrum of GW sources. She is co-supervised by Dr. John Ruan at Bishops.

PhD Graduate Student

Eliot Raschetti

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