Osmar R. Zaïane is a Professor in Computing Science at the University of Alberta, Canada, and Scientific Director of the Alberta Machine Intelligence Institute (Amii) since 2009.

His research interests are at the confluence of the broadly defined fields of knowledge discovery from large databases and information retrieval. That includes data mining from the Internet/Web encompassing web mining related to the content of web documents, the structure of the hypertext documents, and the usage of the World Wide Web. Lately, he is giving special attention to research related to data analysis in the realm of health/medical informatics.

Dr. Zaiane joined the University of Alberta in July of 1999. He obtained a Master's degree in Electronics at the University of Paris, France, in 1989 and a Master's degree in Computer Science at Laval University, Canada, in 1992. He obtained his Ph.D. from Simon Fraser University, Canada, in 1999 under the supervision of Dr. Jiawei Han.

His Ph.D. thesis work focused on web mining and multimedia data mining. He has research interests in data analytics, namely novel data mining algorithms, web mining, text mining, image mining, social network analysis, data visualization and information retrieval with applications in Health Informatics, e-Learning and e-Business. He has published more than 300 papers in refereed international conferences and journals and taught on all six continents.
