NOTE FROM TED: Please do not look to this talk for medical advice. This talk only represents the speaker's personal business approach to and understanding of gut microbiome, health, and performance. Several claims about the health effects of the technology discussed in this talk warrant further scientific investigation. We've flagged this talk because it falls outside the content guidelines TED gives TEDx organizers. TEDx events are independently organized by volunteers. The guidelines we give TEDx organizers are described in more detail here: http://storage.ted.com/tedx/manuals/tedx_content_guidelines.pdfWhat if you could wear a tracker for your gut, the way you track your sleep or steps?In this powerful and personal talk, former Greek national sprinter and scientist Dr. Mariam Elgabry takes us on her 365-day sprint to decode gut health—showing how longevity begins not in the lab, but at home. From race-day gut flares to building Nurfy, the world’s first home microbiome lab, Mariam shares how science and sport collided to create a daily rhythm for health that anyone can start.Her message is clear: health isn’t a yearly report—it’s a rhythm we can all culture at home.Join her as she launches a one-year experiment to track her gut every day and discover what it truly takes to rebuild performance, resilience, and longevity from the inside out. Dr. Mariam Elgabry is a biochemical engineer, entrepreneur, and former elite sprinter building the future of at-home health. She is the founder and CEO of Bronic, creator of Nurfy, a first-of-its-kind “homeable” micro-lab that uses AI to turn daily gut-health samples into simple, next-day actions. Mariam holds credentials from Yale and UCL, serves as an Honorary Research Fellow at UCL, and has advised on biosecurity and emerging technologies with governments and international partners, including the United Nations. Her work sits at the intersection of microbiome science, cyber-biosecurity, and human performance—translating lab-grade methods into private, accessible tools people can use at home. After years abroad, Mariam returns “home” to prove you don’t need Silicon Valley to build world-changing health tech. She is now launching the first daily gut-microbiome program for female athletes—starting with herself as she trains to re-qualify for the national team. The aim is to build the first female-athlete microbiome performance & longevity dataset, designed biosecurity-first, and to share what works in plain language. On stage, Mariam brings scientist-level rigor and athlete-level honesty—the hard problems, the false starts, and the conviction that longevity begins at home, with courage, curiosity, and compounding daily choices.
