Professor Max Diem is based in the Department of Physical and Biophysical Chemistry at Northeastern University. He did his first degree at the University of Karlsruhe and then his PhD at the University of Toledo in OH. Until 2005 he was at the Central University of New York before moving to Northeastern University. His research interests are is centered on the development of physical / optical methods for medical diagnosis in tissue diagnostics.
