Diana is a documentary film director and through her work she like to move on the edge. Her movies often explore taboo topics like menstruation, infidelity and ageing. 

Her first feature documentary the Moon Inside You was premiered at the 62nd MFF in Locarne as part of Semaine de la Critique (the first Slovak film at the Locarno Festival ever). Since then, the documentary has been selected for over 150 international film festivals around the world (IDFA, Chicago, Montreal, Guadalajara, Sydney, etc.).

She later made a spin-off film to help teenage girls with the hardship of first menstruation called the Monthlies. 

Currently she is interested in the subject of relationships while she's working on another feature doc called Happily (un)Faithful and organising parties for singles.
