Manuel Ujaldon received his B.S. degree in Computer Science from the University of Granada (Spain, 1991) and his M.S. and Ph.D. degrees in Computer Science from the University of Malaga (Spain, 1993 and 1996). During 1994 and 1995 he was a Research Assistant in the Computer Architecture Department at the University of Malaga, where he became Assistant Professor in 1996 and Associate Professor in 1998. From 2000 to 2004 he was also vice-head of the School of Computer Engineering at the University of Malaga, as well as Director of its International Programs.

Dr. Ujaldon spent one year as an invited researcher at the University of Vienna (Austria) and was also a postdoctoral researcher at the Computer Science Department of the University of Maryland (USA, 1996 and 1997) and Biomedical Informatics Department of the Ohio State University (USA, 2003 and 2004), where he currently holds an adjunct appointment as visiting professor.

Research

Project Involvement
