Thank you for visting the Utah State University Luminescence Laboratory homepage! We have been up and running since January 2007. We currently have two RISO TL/OSL Readers and one with a single-grain attachment.

We specialize in the analysis of the optically stimulated luminescence (OSL) signals from quartz sand grains in geomorphological and geoarchaeological applications. We are also equipped to measure Infrared Stimulated Luminescence (IRSL) on potassium feldpsar. Please explore the 'Projects' and 'Publications' pages for examples of internal and external projects that the Lab has been involved with.

Come see our sessions, talks, and posters at GSA 2015 in Baltimore, MD!

Dr. Tammy Rittenour runs a two-week OSL training course for students and professionals, usually in June. Click on 'Summer short course' in the menu to the left for more information.

Thank you to everyone who made the 9th NWLDW in Logan a great success! See the conference proceedings in Quaternary International.
