Ska Keller is in the running to succeed Jean Claude Juncker and land the EU's top job.
We interviewed her ahead of European Parliament elections in May.
Here is our profile of the Green MEP.
Who is Ska Keller?
Ska Keller is a German politician, born in Germany in 1981. She studied Islamic Studies, Turkology and Jewish Studies and the Free University of Berlin and the Sabanci Üniversitesi Istanbul, and completed her degree in 2010.
Before being a member of the European Parliament, Keller was a chairperson and spokesperson on women's policy for Alliance 90/The Greens in Brandenburg and a board member of the German Young Greens.
She was then elected to the Parliament when she was only 27 years old in 2009.
In 2014, Keller was the European Greens' front runner for the European elections. She is now in her second term of office.
She is the president and migration spokesperson for the Greens/EFA group in the European Parliament.
She is a member of the Committee on Civil Liberties, Justice and Home Affairs (LIBE), where she works to strengthen the rights of refugees and migrants and achieve a fair asylum policy on the EU.
She is also a member of the European Parliament's Turkey and Mexico Delegations.
What does she stand for?
Keller criticises the misrepresentation of people in the European Parliament. She explains that the Parliament is mostly populated with men in their fifties or older, which does not reflect our society. She thinks everybody should be represented, wants to represent young people and include their needs and opinions in her work.
Improve people's lives and protect people everywhere
She wants to protect people and ensure that other parts of the world don't suffer from EU trade policies. She wants a fair Europe, that protects people inside and out of its borders, and ensure human rights are respected around the world. She wants to welcome refugees and ensure they can legally immigrate to the EU.
She believes in being completely transparent about her work. On her website, she reserved a page to expose what she earns as an MEP and how she spends the money.
Social media engagement
Below is her most liked post on Facebook since 2009 where she criticises corruption in Romania.
On her Instagram account, she posted a picture with Greta Thunberg during their conversation about climate change.
