Juan Rubén is interested in how people decide what to believe, whom to trust, and how technology shapes those decisions. He is particularly interested in how emerging technologies are reshaping information, communication, and social life.

His perspective draws from experience across industry, research, academia, and community work. At Twitter and Reddit, he worked on misinformation, disinformation, radicalization, election integrity, new communication channels, and trust and safety. He has also built several startups, with varying degrees of success and no shortage of life lessons, worked at the Center for Effective Global Action, and mentored young people in underserved communities. He studied information and recommender systems at Cal State Long Beach before earning a master’s degree in computational social science from UC Berkeley.

Juan Rubén grew up in Los Angeles in a big Latin family and later made homes in San Francisco and New York. Outside of work, he gravitates toward travel, art, community, building digital and physical technology, and trail running. He is especially drawn to the rituals, stories, and acts of hospitality that help people make sense of one another and turn unfamiliar places into familiar ones.
