U professor now under scrutiny 

cut from last NSF grant partly 

because of job in Washington, D.C.

From the Strib:

..learned from the National Science Foundation that since the U and the Department of Justice investigated him, he had worked on another NSF grant, in 2004.

However, he was removed from that project in 2005.

A document shows that Marquette University, the organization that got the grant and subcontracted with Polla for part of the work, requested to remove him from the project.

It also notes that Polla was working full time for the federal government:

"Being away in Washington, D.C., it would have been difficult for him to recruit and direct a new graduate student's work at the University of Minnesota."

Polla does not do any research for the U now, his boss says.
