Dr Isabel Torres leads the advocacy organization Mothers in Science. She had been collecting data and providing solutions through science, stories, networking, toolkits and polices. I wanted to speak with Isabel because as a mom in STEMM, which includes medicine, I wasn’t aware of the gender barriers and bias I faced. I assumed I was somehow failing. But Isabelle and others have shown that mothers are penalized in their scientific careers but fathers are not. This difference points to a systemic problem which Isabel is fighting to dismantle.
