The Team
Welcome to CTextA at the Tel Aviv University Center for Artificial Intelligence and Data Science (TAD). We support Tel Aviv University faculty members and research students in integrating computational text analysis into their research.
Does your research involve textual data? Whether you work in the humanities, social sciences, law, management, arts or another discipline, we welcome the opportunity to explore how computational methods can support your research questions. These methods include natural language processing (NLP), large language models (LLMs), and generative AI.
Whether you are developing an initial idea, planning a thesis or dissertation, preparing a grant proposal, or working on a research paper, we invite you to contact us to discuss your goals and possible collaboration.
Explore our website for tutorials, examples of research projects, and information about our workshops and events. Join our mailing list to stay informed about upcoming activities.
We look forward to working with you!

Meet the team
Dr. Vered Silber-Varod
principal Consultant for Digital Humanities and Social Sciences (DHSS) at TAD
Dr. Vered Silber-Varod is the Chief Advisor for Digital Humanities and Social Sciences (DHSS) at TAD. She has experience in leading research projects in the field of digital humanities and social sciences, and understanding of the challenges in the field, in theory and in practice.
Her academic work is characterized by interdisciplinarity, mainly of the interface between the spoken language and technological applications and in her doctoral thesis she combined linguistic knowledge with a large-scale corpus and analysis with computational tools.
From 2018 to 2022 she was the director of the Open Lab for Media and Information (OMILab) at the Open University of Israel. Between 2013-2017 she was the Research Fellow at the Center for Research on Innovation and Learning Technologies.
Over the years she was chairman and member of the committees of many academic conferences, local and international, and initiated many seminars and workshops. She has published dozens of articles in journals and at international conferences.

David Refaeli
Statistician, Data Scientist, and Science Communicator
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.
