She works as a cross-genre artist in the fields of performance and visual arts,[1] often addressing non-normative femininity and gender expression.

The Queen Barbie Lodge regularly organized exhibitions and performances ironizing sexism and championing female empowerment.

The Berlin city magazine Tip wrote: “Lena Braun aka Queen Barbie is not only a curator, but also a visual artist and above all an intrepid performer.

In the 1990s and 2000s, she wrote plays, acted in films [8] and published a periodical for the Queen Barbie Lodge (36 issues, Xerox art).

For an exhibition on "Today's Avant-Garde" at the Kindl Center for Contemporary Art in Berlin (2017) [9] Braun created an installation that reflects her point of view: "My art spaces are campy environments that shape alternative queer lifestyles and suspend classic markers of social exclusion such as age, origin, or saleability.

[23] Braun was a voice actress in Nekromantik 2,[24] and she co-wrote and co-directed a film for German television (“Der hellblaue Engel”, The Light-Blue Angel, 1996).

They are an attempt to revive history, or rather, repressed and misrepresented history.”[32]Braun processes the photos taken during performances into prints and collages.

"[33] The genres of collage and installation remain central to Braun's work today, with a wide range of materials including found objects of all kinds.

For her, the 100th anniversary of the German art school Bauhaus was an invitation to suspend its gender code - concrete for men, weaving for women – by working in both media.

Her concrete casts immortalize found objects in sculptural works that turn into a kind of time capsule.
