Mateo Vargas is a Brazilian-Canadian science communicator and curious mind, with a soft spot for all things brain-related. Diagnosed with ADHD as an adult, Mateo left a career in corporate comms to explore the intersection of neuroscience, self-experimentation, and everyday life. He’s especially interested in how we can create focus and energy through small rituals, tools, and science-backed hacks — without falling into toxic productivity traps. His writing combines scientific research with lived experience, covering topics like nootropics, creative burnout, attention cycles, and sleep optimization. Off-screen, you’ll find him testing cold showers, sketching out video scripts, or getting lost in an indie bookstore.
