Heather Quigley is the founder of Signal + Flow, a coaching business helping women in STEM navigate one of the most pivotal career transitions: moving from individual contributor to people leader. A chemical engineer with a PhD and 23 years of combined academic and industry experience, she built Signal + Flow after navigating that transition herself without a roadmap. Her flagship program, The Real Rules of STEM Leadership, gives women the tools, clarity, and conviction to lead with confidence in environments that weren't built with them in mind.
