EMR Research Summaries

One of the important goals of the MagLab is to facilitate the exchange of scientific knowledge and to communicate the science and engineering achievements of the laboratory’s faculty and users. These Research Summaries showcase the cutting-edge research underway in the EMR program. For a list of recent research generated from all our programs, please visit our main Research Summaries page.
