Hi! I’m a postdoctoral researcher studying stellar evolution, pulsating stars, and binaries.

Employment history

Postdoctoral researcher
Radboud University – Nijmegen, The Netherlands
(06/2021 – current)
I’m currently working with data collected by the BlackGEM telescope array. I’m using these data to search for variable stars and binaries across the Southern sky.

Postdoctoral researcher
(06/2020 – 05/2021)
I researched pulsating stars in eclipsing binaries, and used these stars to calibrate state-of-the-art stellar evolution codes.
