Ghina is an astrophysicist born in a small village tucked among the thousand-year-old cedars of Mount Lebanon. A curious child, a toy’s motor and battery were her objects of fascination. As a school kid, she installed a light system in her dark blue bag to make it easier to find her books. She found physics challenging so it lured her into it as a major in college, and later as a Masters degree. She then did her PhD in Astrophysics, during which she studied the structure and evolution of stars. She is a public speaker at international conferences and global forums including TEDx, and the UN. She was featured as "Modern Muse for Astronomy" by the cultural magazine Postscript.

Martha Irene is a Mexican astrophysicist who is excited to share her passion for science with the world. Since she was a kid and because of her father, who is a philosopher, she was motivated by the question: "Where do we come from?" So she started a Bachelor's degree in physics in Mexico then spent a few months working at the Space Telescope Science Institute. She continued her education in astrophysics in the Astromundus Masters programme in Europe and then started her PhD in astrophysics in the Netherlands. For her research Martha Irene creates computer simulations of stars and planetary systems to study what happens to them as they grow old.

Francesca is from Puglia in Italy where she studied Biotechnolgy and Nanobiotechnology at the University of Salento. After graduation, she came to Cambridge with the Erasmus programme and then spent 10 months as a visiting student in KAUST, in Saudi Arabia, working on 3D bioprinting. She is now in Cambridge doing her PhD in Chemical Engineering and working on cancer research. Francesca likes baking, playing tennis, volleyball and ultimate frisbee. She decided to join She Speaks Science to bridge the gap between the science community and the public, focusing on the accomplishments if thousands of women to inspire the future generation of scientists.

Roberta is from Italy and graduated in Foreign Languages and Communication at the University of Salento. She also studied at City, University of London, where her research focused on the gendered stereotypes that influence people's career choice and work experience. As a PhD student at the University of Granada, she works on the representation of femininity, motherhood and maternity on social media during Covid-19 era. Roberta loves reading novels, traveling, art, and has two children. Her experience as a mother inspired her to work with She Speaks Science, as she would like her children to grow up in a more equal, fair, inclusive world.

Lynn is a Lebanese computer science and psychology student at the American University of Beirut. Her parents always encouraged her to pursue her talent for maths and as a young adult, she wanted to do the same for others: she founded a student club to empower youth in refugee camps across Lebanon. At university, Lynn’s experience as one of the few female computer science students was disappointing as she was consistently ostracised by her male peers. She became motivated to reach out to other women in STEM. The ‘She Speaks Science’ mentorship programme has helped her verify the power of female representation.

Dr. Alfredo Carpineti is an astrophysicist, journalist (IFLScience), science communicator, and social activist. He's the chair and founder of Pride in STEM, an award-nominated charity working to raise the profile and showcase the work of LGBTQ+ people working in STEM. He was one of the organisers of International Day of LGBTQ+ people in STEM.

Matt is an outreach astronomer based in Cambridge, UK. His PhD at the University of Cambridge focussed on star formation and the evolution of galaxies across cosmic time. After a few years as a postdoctoral researcher, he realised that his passion lay more in the direction of science communication and education. Since 2017 he has been an outreach astronomer at the University of Cambridge’s Institute of Astronomy.
