Project:  Visualization interface for the Uranium isotope database
Disciplines:  Geochemistry, Computer Science
Mentor:  Francois Tissot, Assistant Professor, (GPS),
Mentor URL:  (opens in new window)
AO Contact:  Haoyu Li,
Background:  The study of uranium (U) isotopes has found applications in a variety of fields including geo/cosmochronology, oceanic paleoredox reconstruction, magmatic differentiation, environmental remediation, and forensic studies. With thousands of newly reported U isotope data each year, a need exists for a comprehensive U isotope database. Our group recently developed a Uranium Isotope Database (UID,, which is a comprehensive, freely accessible, updatable, and internally consistent uranium isotope database. The current version of the UID is an exhaustive Excel sheet. As a result, the user has to download the Excel file to access the UID. To improve the user experience, there is a need to develop an online and interactive searchable database with built-in visualization capabilities.
Description:  The project involves developing a user interface for the UID. The student will work with a graduate student or postdoctoral fellow to design the architecture and functions of the database webpage, as well as the approaches to implementing these features.
