The Faculty History Project documents faculty members who have been associated with the University of Michigan since 1837. Key in this effort is to celebrate the intellectual life of the University. This Faculty History Website is intended as a component of the effort to document the extraordinary academic achievements of Michigan’s faculty in building and sustaining one of the world’s great universities. It provides access to a comprehensive database of information concerning the thousands of faculty members who have served the University of Michigan.

Research Interests
The central research interest of our group is the exploration of how magnetic moments form or survive in the metallic environment, as well as the interplay of moment stability and magnetic order. Currently, our experiments center on three different areas. First, we are interested in the unusual critical phenomena associated with zero temperature magnetic phase transitions in heavy fermion intermetallic compounds, especially the roles of disorder and limited dimensionality. Our second research focus is with the properties of the electron gas at low densities, where strong and unscreened Coulomb interactions are expected to lead to unusual types of charge and spin order, especially in very large magnetic fields. Finally, we have a new project in which we study the dynamics of magnetic nanoparticles, with the aim of studying the role of spatial confinement on magnetic freezing.
We use neutron scattering as well as a variety of transport, magnetic, and thermal measurements to probe the ground state and its excitations of these strongly correlated systems. These measurements are carried out at temperatures as low as 0.01 K, magnetic fields as large as 60 Tesla, and pressures as large as 200,000 atmospheres. Neutron scattering measurements are carried out at both reactor and spallation sources in the US and Europe.
