Marcus' research involves work with electron motion and submicron electronic devices, which have applications to computing information and technology.
"Charlie has made important advances to our knowledge of quantum chaos," said McKay Professor of Applied Physics Robert M. Westervelt, who was Marcus' Ph.D. research adviser at Harvard in 1990.
"I look forward to working with Charlie in developing new approaches for education and research at Harvard," Westervelt added.
The department decided to "attract Marcus away from Stanford last summer," Nelson said. Marcus had been an assistant professor of physics there.
Marcus was at a conference yesterday and unavailable for comment.
