The National Academy of Sciences (NAS) appoints Yannis C. Yortsos as Editor-in-Chief of the PNAS Nexus -

The National Academy of Sciences (NAS) has announced the appointment of Yannis C. Yortsos as the next editor-in-chief of PNAS Nexus. Yortsos succeeds Inaugural Editor-in-Chief Karen Nelson.

PNAS Nexus is a selective, open-access journal with a focus on innovative and interdisciplinary work across the biological, physical, and social sciences, particularly encompassing engineering and the health sciences.

Yortsos is dean of the Viterbi School of Engineering and Chester Dolley Professor of Chemical and Petroleum Engineering at the University of Southern California (USC). As dean, he also holds the Zohrab Kaprielian Dean's Chair in Engineering. He was elected to the National Academy of Engineering (NAE) in 2008 and has served as a member of the NAE Council since 2017. Furthermore, Yortsos has served on the PNAS Nexus Editorial Board as a deputy editor since May 2022 and as interim editor-in-chief since September 2022.

Yortsos has made fundamental discoveries in fluid flow, transport, and reactions in porous media. He has used statistical physics and applied mathematics to model the interaction of heterogeneity and physicochemical processes. Yortsos received a BS degree from the National Technical University of Athens, Greece, and MS and PhD degrees from the California Institute of Technology—all in chemical engineering.

Along with colleagues at Duke University and Olin College, in 2009 Yortsos co-founded the Global Grand Challenges Scholars Program, which is aimed at educating students to address pressing challenges in engineering. The program has been adopted by nearly 100 universities. As a testament to the program’s impact, Yortsos and colleagues received the 2022 Gordon Prize of the NAE. Between 2012 and 2017 Yortsos chaired the Diversity Committee of the Engineering Deans Council, leading an engineering diversity initiative that has since been adopted by more than 250 engineering schools nationwide. From 2018 to 2021, Yortsos was a principal investigator of the National Science Foundation’s gender equity initiative EDGE.

Yortsos has received numerous scientific honors, including honorary membership in the American Institute of Mining, Metallurgical, and Petroleum Engineers (2011), associate membership in the Academy of Athens (2013), an honorary degree from Tsinghua University, China (2017), and a Los Angeles area Emmy (2022) for the creation of the documentary Lives not Grades on Engineering Innovation for Global Crises. He is a Fellow of the American Association for the Advancement of Science.
