Hundreds of women scientists joined together with hundreds of thousands of demonstrators at the Women’s March on Washington on the 21st of January, just a day after Donald Trump was sworn in as president of the United States of America. After Donald Trump won the election in one of the most controversial and polarized presidential races ever witnessed in the country, a new advocacy group called “500 Women Scientists”  was established. Women scientists face incredible institutional and systemic barriers such as sexism/misogyny, racism for black/women of color scientists, elitism/classism, in order to become and succeed as scientists. In the face of a president who has openly declared war on the science community, these women scientists are boldly fighting back but also striving to bring justice into their own work.
