Her current work addresses themes of gender, identity, socioeconomics, and politics, examining issues that impact the contemporary world.

[3] As Rush began archiving her career in 2015, she started making work addressing the effects of the art market, gentrification, class warfare, gender bias, and other kinds of discrimination.

This is portrayed in her series Evidence of Being (2014–present), which questions what constitutes success and what she describes as the importance and nature of being an artist working in the face of bias.
