Dr. Dionisio holds a B.S. from Loyola Marymount University awarded 1991 as well as an M.S. (1993) and Ph.D. in 1996 from the University of California, Los Angeles. Prior to joining LMU, Dr. Dionisio worked with the UCLA Medical Imaging Informatics (MII) group from 1997 to 2001 and co-founded Medaxis Corporation, a health care information system vendor, in 2001. He continues to consult for Medaxis and is a member of its board. At LMU, he co-directed the NSF-supported Recourse project, which adapted the open source culture to the university's computer science curriculum. In 2006, he started a collaboration with biology professor Kam Dahlquist to extend these open source principles to bioinformatics courses that were coupled with the open source XMLPipeDB project. Dr. Dionisio's personal research interests lie in interaction design and computer graphics, as well as in applications that cross and bridge computer science with other disciplines.
