The Team
Welcome to the CTextA team at the Tel-Aviv University Center for Artificial Intelligence and Data Science.
If you are a researcher in a text-based field in the Humanities, Social sciences and even Healthcare and want to incorporate advanced Natural Language Processing models and techniques in your next paper or grant proposal - we want to collaborate with you! Feel free to contact us for any question or idea.
In this website you can find tutorials, exemplary project and information about workshops and events that we hold from time to time. Join our mailing list to get updates on upcoming events.
Looking forward to working with you,

David Refaeli is a statistician, data scientist, and science communicator specializing in statistical modeling, machine learning, and artificial intelligence. He holds a Master's degree in Statistics with honors from Tel Aviv University and began his bachelors in Statistics while still in high school.
His work combines rigorous statistical methodology with practical applications in data science and software engineering. Since 2025, he has been working at the CTextA laboratory, where he develops computational methods for large-scale text analysis. His work includes topic modeling, automatic document annotation and classification, and the development of AI-assisted tools that help researchers identify relevant passages and extract insights from large text corpora.
In addition to his background in statistics, David is a self-taught programmer who has worked as both a software developer and a team leader. He is also the creator of the popular educational YouTube channel Meerkat Statistics, where he teaches advanced concepts in statistics, probability, and machine learning to students and practitioners worldwide.
Beyond science and technology, David is also an author. His debut novel, My Love for the Tin Woman, published in 2026, reflects his interest in language and storytelling.
