Historically, the STEM fields (science, technology, engineering, and math) have been male-dominated. Women have fought and continue to fight a long and hard battle against the glass ceiling in order to gain recognition in STEM. Here are a few important women in STEM who are truly inspirational:

1) Dr. Fabiola Gianotti

Dr. Fabiola Gianotti is an esteemed Italian physicist and the first female director-general of CERN, the European Organization for Nuclear Research. She was selected as the director-general in 2014 and took up the position in 2016.

2) Red Burns

Red Burns is a professor who has encouraged students to launch startups, new communications technologies, and media companies. She is the founder of the Interactive Telecommunications Program at NYU. This program is so prestigious that it is known as the Harvard of Interactive.

3) Helen Greiner

Helen Greiner is the co-founder of iRobot. iRobot is most well known for the Roomba automatic vacuum, but Greiner has made a larger impact than that. She has also created the PackBot robot, which is designed to make soldiers feel safer and more effective. She has resigned from her previous position as chairman of the Board of iRobot, but she still serves on the board of direction. She is currently the CEO of CyPhyWorks, a Massachusetts-based company that creates small, unmanned flying robots.

4) Angela Benton

Angela Benton is the founder and CEO of NewMe Accelerator. This organization works to educate and empower women and people of color in the field of tech.

5) Caterina Fake

In more ways than one, Caterina Fake has become a female icon of Web 2.0. She is a co-founder of Flickr, a popular photo website that has been acquired by Yahoo! Fake is also the co-founder of Hunch, a site that was acquired by eBay in 2011. She is currently Chairman of the Board of Etsy and is on the board of directors of Creative Commons.

6) Sheryl Sandberg

Sheryl Sandberg is undoubtedly one of the most successful women working in the field of technology today. Sandberg has had a large impact as the Vice President of Global Online Sales and Operations at Google, as well as in her current position as Chief Operating Officer of Facebook. As the COO of Facebook, she has worked to implement policies that positively impact women, such as maternity leave and accessible child care. These aren’t the only impressive titles she’s held. Because entering the technology world, Sandberg was the Chief of Staff for the U.S. Department of the Treasury.

These women in STEM are showing the young women and girls of today that they can do anything. We have a ways to go before achieving equality, but these women certainly are paving the way.
