Forbes recently challenged women from a variety of fields with a question:

Who is paving the way for girls and women in the future?

I was thrilled to have the opportunity share my my own power list of five trail blazing women who are key architects for change and empowering women worldwide. For the full article featuring women changing the world in Media, Maternal Health, Public Policy, Philanthropy, Business, Sports, and beyond check out:  Forbes: Women Changing the World

Here are my top pics for women changing the world in STEM (Science Technology Engineering and Mathematics):

Marissa Mayer, CEO, Yahoo!

In a masterful stroke of glass-ceiling shattering, Marissa Meyer boldly announced her first pregnancy on the same day that she accepted the helm of Yahoo! Working mothers everywhere cheered as Marissa did so publicly what they do privately every single day: She’s making it work to work.

Rosalind Hudnell, Chief Diversity Officer, Intel

The force behind Intel’s Computer Clubhouse Network, which over the past decade has touched 50,000 youth in STEM focused afterschool programs around the world. Not satisfied with that, and in collaboration with President Obama’s Council on Jobs & Competitiveness, she developed the Stay With It initiative, the first ever national online support network for students pursuing degrees in engineering and computer science.

Kristen Titus, Executive Director of Girls Who Code

Activist. Technologist. Feminist. Culturalist. Idealist. Titus is all that, and she is the Executive Director of Girls Who Code, an organization working to educate, inspire and equip 13- to 17-year-old girls with the skills and resources to pursue opportunities in technology and engineering. Girl coders = good for business.

Noorjahan Akbar, Cofounder, Young Women for Change

Dozens of women flock each day through the discreetly marked doors of Akbar’s Sahar Gul Cafe, Afghanistan’s first all-female Internet café. Through Young Women for Change, she is ensuring that Afghan girls and women have a safe place to connect to the world and have a platform to socialize, study and advocate.

Esther Duflo, Founder and Director, Jameel Poverty Action Lab, MIT

Takes economics out of the lab and into the field to discover the causes of poverty and high-impact ways to eradicate it. Asks questions like, “If more girls could afford a school uniform, would more girls go to school?” and watches the data make the arguments for her.
