Dr. Andrei Dragomir joined the Department of Biomedical Engineering in February 2010. He earned his B.Sc. in Electrical Engineering from the Politehnica University, Bucharest, Romania in 1999 and his M.Sc. and Ph.D. in Biomedical Engineering from the University of Patras, Greece in 2002 and 2006, respectively. He was a postdoctoral fellow at the Harrington Department of Biomedical Engineering, Arizona State University.

Education: 

Ph.D., Biomedical Engineering, University of Patras (Greece)
M.Sc., Biomedical Engineering, University of Patras (Greece)
