Born: 1971

Interests: human-computer interaction, image processing, artificial intelligence, face analysis, neural networks, pattern recognition, machine learning

Details:
Ioan Buciu received the Diploma of Electrical Engineering in 1996 and the Master of Science degree in microwaves in 1997, both from the University of Oradea. From 1997 to 2000, he served as a Teaching Assistant with the Department of Applied Electronics, University of Oradea. During 2001 - 2005, he was a researcher and a PhD student at the Artificial Intelligence and Information Analysis Lab, Department of Informatics, Aristotle University of Thessaloniki, Thessaloniki, Greece. Currently he is with the Department of Applied Electronics, Electrical Engineering and Information Technology, University of Oradea. His current research interests lie in the areas of image processing, pattern recognition, machine learning, and artificial intelligence. Also, his area of expertise includes face analysis, support vector machines, and image representation. Besided, I am interested in finding new techniques for feature selection and dimensionality reduction, especially using kernel methods.
