The 2025 HerCatalyst Public Health Conference was an exciting half-day event designed to inspire the next generation of changemakers in public health. The day began with a keynote from leading public health professionals, followed by an interactive research symposium with two tracks—one for beginners looking to develop a research idea, and one for students ready to dive deeper into applying and refining their projects with expert guidance. Throughout the day, attendees heard from powerful speakers, explored real-world challenges, and engaged in a dynamic panel discussion with opportunities to ask questions. With workshops, networking sessions, and exhibitions showcasing innovative ideas and technologies, the conference created an accessible and inclusive space for girls and young women to explore their interests, connect with mentors and peers, and take meaningful steps toward becoming leaders in STEM and public health.
