Daniel Patrick Phelan

Assistant Physicist


Danny Phelan is an assistant physicist in both the Emerging Materials and Neutron and X-ray Scattering groups.  He received his B.S. and Ph.D., both in physics, from the University of Virginia in 2002 and 2008, respectively.  Subsequently he was awarded an NRC postdoctoral fellowship at the NIST Center for Neutron Research and then worked as a postdoc in the Chemical Engineering and Materials Science Department at the University of Minnesota.  He joined the Materials Science Division at Argonne in 2014.

Danny’s research combines crystal growth; characterization of magnetic, thermodynamic, electrical transport, and dielectric properties; and neutron and x-ray scattering experiments in an effort to understand the microscopic physics underlying material behavior.  He runs the electrical transport and magnetization laboratory in the Emerging Materials Group and is a frequent user at neutron scattering facilities such as NCNR, HFIR, and SNS.  He has worked on topics ranging from magnetism in transition metal oxides to relaxor ferroelectricity and superconductivity.
