Sofia Petrou
Sofia holds a B.S. in Information Systems from the University of Athens and an M.Sc. in Digital Product Design from UCL. As a UX researcher, she worked on heavy enterprise dashboards, turning field studies into interfaces that reduce cognitive load and decision time. She later helped stand up design systems that kept sprawling apps consistent across languages. Her writing blends design governance with ethics: accessible visualization, consentful patterns, and how to say “no” to a chart that misleads. Sofia hosts webinars on inclusive data-viz, mentors designers through candid portfolio reviews, and shares templates for research readouts that executives actually read. Away from work, she cooks from memory, island-hops when she can, and fills watercolor sketchbooks with sun-bleached facades and ferry angles.
