Name: Alice Gray
What you need to know: The science blogger from South Wales has made it her mission to get more women into STEM and to raise awareness of the roadblocks women in the industry are up against, which she writes about on Mind-Ful of Science.
"Women are incredibly underrepresented in science, technology, engineering and maths, and are significantly more likely to be employed below their skillset. Not only are women being stopped from reaching their full potential, but studies have shown that lack of diversity can really affect the quality of scientific research," she says.

Who: Jessy McCabe
What you need to know: When 17-year-old McCabe noticed that her A-level music syllabus didn't include a single female composer, she launched an online campaign, wrote letters to the education secretary, Pearson and exam regulator Ofqual, and guess what? The A-level syllabus now includes five works by female composers. That's called getting it done.
"This has got to change. How can we expect girls to aspire to be composers and musicians if they don’t have the opportunity to learn of any role models? How can we accept that the UK's largest awarding body doesn't adequately acknowledge the work of female musicians? Why are we limiting diversity in a subject which thrives on its astounding breadth?" she wrote.

Who: Meltem Avcil
What you need to know: Avcil has seen more than most women three times her age, when she was detained in the controversial Yarl's Wood Immigration Centre at the young age of 13. A campaigner and activist, Avcil wants to ensure no other girls have to go through what she did. She joined the charity Women for Refugee Women's campaign to end the detention of children at Yarl's Wood and is now fighting to close the centre down and stop the detention of female asylum seekers, with a petition that has already amassed over 100,000 signatures.
"I couldn't move on knowing a place like Yarl's Wood exists," Avcil has said. "Just because I was free, why shouldn't I do anything about it? When I was in the centre, I never imagined I'd be backing a petition with so much support so I'm really shocked and grateful that I've been able to do this."
