Kartikay Chadha is a Researcher in the Visual Analytics Laboratory (VAL) and manages a major multi-institutional collaborative data visualization research project, funded by the Social Sciences and Humanities Research Council of Canada (SSHRC), entitled Creating a Visual Language of Marks ( He holds a Master of Science degree from the University of Toronto and a Bachelor of Technology from the VIT University in India. His research aims to develop computational algorithms, tools including websites and databases, to store, visualise, and analyse large volume datasets for meaningful information retrieval.

Kartikay joined VAL in 2014 as a Mitacs Globalink Intern during an undergraduate placement with Dr Martha Ladly. He now leads Ladly’s technical team with his expertise in computer programming, and big data quantitative and qualitative analyses. He is currently researching on various modes of interaction for historians with historical data, to leverage the applications of human-computer and human-information interaction to facilitate information retrieval using data visualization technologies. Kartikay has contributed to other on-going VAL projects including the Postcard Memories, the CBC Holodeck and the Elders, Memory and Visualization research projects. Kartikay holds a Researcher affiliation with The Big Data Research, Analytics, and Information Network (BRAIN) Alliance at York University, an Ontario network of Universities, public and private institutions, working together to conduct state-of-the-art translational research on large-scale data sets (

During his education and work career, Kartikay has developed multiple websites, databases and web-application for research projects based at institutions including OCAD University, Centre for Addiction and Mental Health, University of Toronto and York University in Canada, the University of Colorado Boulder in the United States, and the University of Essex in the United Kingdom. Kartikay is the lead developer of the Decoding Origins Web Portal (, an online open-source content management tool that is currently used by academic researchers at institutions in North America, Europe and West Africa to collaborate, curate and research historical manuscripts. Very early in his career, Kartikay has presented his research work at multiple national and international academic conferences and has published in peer-reviewed journals. He is also working as a Technical Team Lead for Dr Paul Lovejoy’s research group, at the Harriet Tubman Research Institute in York University, Toronto. He is currently leading the technical development and production of over 13 African Digital Humanities research projects.
