The INSTAAR Stable Isotope Lab at the University of Colorado is hosting the Front Range Isotope Day (FRIDay) on Friday August 21^th 2026.��

FRIDay meetings are an annual, gathering of scientists and technicians from institutions along the Front Range who use stable isotopes in their research. Participants come from a broad range of scientific backgrounds, but we use common research tools and instrumentation. Students are especially encouraged to participate.

In this one-day meeting we’ll learn how researchers are using familiar measurements in different research fields, and how technicians are tackling age-old problems in our analyzers - both isotope ratio mass spectrometers and cutting edge optical methods. This is a great venue for talking shop, showing off proud solutions to technological challenges, and sharing the favorite pieces of our isotope toolkits. We’ll also report the cool science that we’ve learned from various isotopic tracers, and gather useful feedback on our work. Most of all, we’ll build community - so that we have friends “in the business” from up and down the Front Range that we can reach out to for troubleshooting and collaboration (or maybe even just a borrowed filament in a pinch).

This is the best kind of meeting because it is casual, friendly, and fun.��We are looking forward to seeing you.��Please spread the FRIDay word, along the Front Range and beyond!

Contact: If you have any questions, please email Sylvia Michel (INSTAAR Stable Isotope Lab).��

Talks & posters

The agenda will include:

Science talks – presentations with some background, methods, results. Because we all love science!

Tech talks – presentations showing clever solutions to tricky problems. If you are proud of it, please tell us about it!

Posters/Student Posters – A few neat plots and a bit of background so we can get to know you and the awesome project that you are working on. THERE WILL BE A CASH PRIZE for best student poster, courtesy of our sponsors, and fun prizes for non-student posters!

Abstract submission deadline is July 24, 2026
