Research Facilities

 The institute houses many state-of-the-art facilities and services to support the diverse group of IUE scientists and their research programs. IUE has a Research Center for Instrument and Physical Facilities, which provides a basic supporting system and broadly divided into four categories: microstructure, measurement, processes modeling and data analysis, cell and molecular biology. Scientists also have their own group laboratories and specialized instruments to support their groups for intensive laboratory research.
