Gruszka graduated from the Theatre Academy in 2003. She is well-known for the role of Gienia in the TV series Boża podszewka / God's Lining, directed by Izabella Cywińska. The watershed of Gruszka's career was the part of Ola in Kochankowie z Marony / The Lovers of Marona, for which she received the best actress award at the 30th Polish Film Festival in Gdynia and a nomination for the Eagle 2007 Polish Film Award. She is among a small group of Polish actresses also cast in foreign projects, including David Lynch's Inland Empire.
Gruszka's adventure with acting began when she was nine. Noticed in a children's television programme by agent Jerzy Gudejko, she was an extra in Krzysztof Zanussi's Chopin w zamku / Chopin's Concert in 1993. Her parents were afraid that auditions would make her drop out of school, so she debuted later. When she was 14, Gudejko contacted her and recommended her to Cywińska. That was how the teenage Gruszka ended up playing Gienia in the series God's Lining.
The actress thinks working with Cywińska taught her the most: "She showed me that this profession can be a way of understanding yourself and the world". The other filmmaker she says influenced her attitude to acting was David Lynch: "I learned from him that you have to trust your intuition and fight for your ideas". She was also Wiktoria in Marek Koterski's Wszyscy jesteśmy Chrystusami / We're All Christs, Magda in Robert Wichrowski's comedy Francuski numer / The French Trick, and had roles in films and TV series by directors including Kazimierz Kutz, Maciej Dejczer, Filip Bajon and Jan Jakub Kolski. Lately she has played the object of the main character's love in Marcin Kryształowicz' s Pani z przedszkola / All About My Parents (2014). The role gained her her second nomination for the Eagle In 2017 the audience will have the chance to see her in three highly anticipated movies: Michał Rosa's Szczęście świata / World's Luck, Maria Sadowska' s Sztuka kochania. Historia Michaliny Wisłockiej / The Art of Loving. Michalina Wisłocka's Story and in the title role in the international co-production Marie Curie directed by Marie Noëlle.
Gruszka was a member of the National Theatre in Warsaw from 2003 to 2008. After she married Russian playwright and director Ivan Vyrypaev, she mostly appears in plays written and directed by him, such as July (2009), Delhi' Dance (2010) and Unbearably Long Embraces (2015). She has worked with Vyrypaev on films and stage productions, in Poland and Russia.
