Founded the University of Minnesota Underground Laboratory at Soudan in 1979 and supervised the expansion of the laboratory in 1984-1986; also collaborated in the second expansion in 1999-2001. During the past 25 years, this Laboratory has added about ~$100 million to the economy of an underdeveloped region of the United States. Established and encouraged outreach activities at Soudan, including a public visitor program, an open day, use of media to explain basic research. Started unique Physics Global Studies course, which takes undergraduate students abroad for a three-week intensive experience (2003, 2005, 2008, 2010). Founded the University of Minnesota Residential College, a program that included up to 450 undergraduate students and integrated academic and residential activities. Represented the 3,000 members of the University of Minnesota faculty in interactions with the Governor and Legislature of Minnesota. Served the University of Minnesota as its Senior Vice-President and Chief Academic Officer during the 1996-1997 conflict between the University Regents and faculty regarding policies on faculty tenure. He also participated in the management of the University’s reorganization of its biological sciences programs and the $225 million sale of the University Hospital. Played a significant role in raising $4 million to endow a Theoretical Physics Institute. He also raised approximately $0.5 million to endow the Abigail and John Van Vleck Lectureship in Physics, which has attracted nearly 20 Nobel-laureate lecturers. Often served as a Visiting Scientist in K-12 schools, principally in a program sponsored by the Science Museum of Minnesota and the Blandin Foundation.

Research Areas
Properties of fundamental interactions, including measurement of neutrino mass, tests of stability of matter (proton decay); high energy cosmic ray physics and astrophysics.

Current Research

I do experiments to determine the characteristics of the fundamental forces in Nature using both particle accelerators and non-accelerator techniques, such as massive detectors to search for proton decay - the spontaneous conversion of matter to energy. I also study very high energy cosmic rays which are incident on the earth from outer space to determine their nature and origin. A particular interest is non-thermal stars as a possible source of cosmic radiation.
