Christopher Walker is co-chair of the Credibility Coalition Misinfosec Working Group.
Christopher is a hands-on player-coach with an extensive knowledge of web- and language-data technologies. Working with diverse teams of engineers, linguists and analysts, Christopher has often managed dozens of language technology projects in parallel, for tasks as varied as speech detection in Dari, speaker identification in Farsi, information retrieval in Chinese and transliteration of Berber Tifinagh.
In 2018, he co-founded MarvelousAI, an early-stage startup building an augmented analytics platform to provide actionable insights regarding online narratives by combining the power of human-in-the-loop learning with the latest in natural language processing, computational linguistics, and machine learning. MarvelousAI is focused on how messaging spreads in online media, both negatively (propaganda) and positively (truth-based messages); which narratives persist over time; and the impact they have on overall discourse about a topic.
