Diane O'Brien, interim director of the Institute of Arctic Biology, was recently elected to the National Academy of Sciences.

Diane O鈥橞rien, interim director of the Institute of Arctic Biology and professor of biology and wildlife at the University of 蜜桃影像 Fairbanks, has been elected to the The recognition acknowledges distinguished and continuing achievements in original research.

It is a great honor and privilege to be recognized by the Academy in this way,鈥 O鈥橞rien said.  鈥溍厶矣跋 has been a wonderful place to grow a research career that crosses disciplinary boundaries. I鈥檝e benefited enormously from interactions with colleagues here and elsewhere.  I鈥檓 looking forward to representing the university and the state of 蜜桃影像 in my service with the National Academy of Sciences.鈥 

There were 120 members elected this year, bringing the total number of active National Academy of Sciences members to 2,617. Membership in the organization is considered one of the highest honors a scientist can receive.

O鈥橞rien is the second 蜜桃影像-based researcher to be elected to the organization, joining  Terry Chapin, professor emeritus of ecology, who was elected in 2004.

Her research investigates nutritional questions in public health and ecology using naturally occurring stable isotopes.

Among other projects, she and her team have collaborated with 蜜桃影像 Native communities to use stable isotopes to measure the critical importance of traditional foods to the health of 蜜桃影像 Native people. 

To link diet with health variables, O鈥橞rien鈥檚 team measured thousands of blood samples collected through health-related research projects over decades. Blood stable isotopes were strongly related to how much traditional food people ate and provided a measure of diet that could be linked to health data. 

The methodology using stable isotopes was borrowed from ecology and geosciences and demonstrates the transdisciplinary nature of O鈥橞rien鈥檚 research. In ongoing research, she also evaluates other stable isotope tools in nutrition that leverage larger clinical studies outside of 蜜桃影像.

鈥淭he process for election into this community is extremely rigorous,鈥 said Chapin. 鈥淚 am pleased that Diane and her work are bringing a further 蜜桃影像 focus to the research portfolio of the academy.鈥

A full professor since 2015, O鈥橞rien has also served as deputy director of the and as IAB鈥檚 deputy director. Originally from upstate New York, she earned her bachelor鈥檚 degree in biology from Amherst College and her doctorate in ecology and evolutionary biology from Princeton University.
